BuslMan – Innovative Design Using Building Information Modelling

Civil Engineering, The 2nd Engineering InnoShow / By

The development of Building Information Modelling (BIM) technology has reshaped our construction industry in many aspects throughout different stages in the project life cycle. Our team, BusIMan, has learnt more about the practical usages of BIM through this competition with our collaboration.
The designed complex is dedicated to the Digital Design & Construction Centre (DDCC). Our design comprises two buildings (South Wing and North Wing) linked by an arch bridge (“The Link”) with a podium underneath. This forms a shape of “CIC” when browsing on the plan view. An iconic bridge (“The Wave”) extends from the complex to the adjacent building, transforming the complex into a district icon. With aesthetic considerations and segmented zones for different facilities type, the complex aims at providing a desirable learning space and a professional working environment.

Automatic Fabric Roll Edge Extractor

Mechanical Engineering, The 2nd Engineering InnoShow / By

Automation technology has been highly adopted by different manufacturing industries in the past two decades. It shows an increasing investment in research and development throughout these two decades to replace labor in production lines. The leading dyeing and finishing machinery development company Fong’s National Engineering Co. Ltd. offered us a project in device designing to smooth their production line. The head of the raw fabric rolls is usually attached with an adhesive tape to prevent the head from falling out in the transportation process. This project aims to design and build a prototype of an Automatic fabric roll edge extractor with the concept of engineering design thinking. The function of the device is to automate the removal process of adhesive tape without any manpower involved.

“On-the-fly” imaging bioassay platform for cost-effective biomedical diagnosis

Biomedical Engineering, The 2nd Engineering InnoShow / By

Optical microscopy is now seamlessly integrated with many bioassay technologies for disease diagnosis. However, current techniques lack the throughput to image large and heterogeneous cell and tissue samples systematically. In addition, the vast majority of the methods overwhelmingly rely on biochemical markers such as stains and antibodies for enhancing image contrast, which are however not always be cost effective and efficient. To address these challenges, this project is to develop a spinning disk bioassay platform, which enables ultralarge-scale, label-free, high-resolution “on-the-fly” single-cell or whole-tissue-slide imaging at an imaging rate of 100-times faster than current assays. This high-throughput and high-content technology could open a new paradigm in data-driven bioassay applied in disease diagnostics, and biotechnology industries.

New Geo-material for Reclamation: Coal Ash-hardened Marine Soil

Civil Engineering, The 2nd Engineering InnoShow / By

Extensive reclamations such as the Airport 3rd Runway System, Tung Chung New Town Extension and the Lantau Tomorrow Vision are proposed and these megaprojects require over 500 million tonnes of backfilling material. However, local fill banks only provide less than 10 million tonnes yearly. In order to alleviate the shortage, this study aims at producing a new geo-material by hardening soft marine soil primarily with coal ash generated from power plants.

Unconfined compression tests were carried out on hardened soil specimens. A set of variables were tested to examine the optimum mix design. About half of the specimens achieved an unconfined compressive strength of over 1 MPa.

The result shows that water to stabiliser ratio and the curing duration are the key strength-contributing factors. It was also found that the unconfined compressive strength of hardened soil is nearly proportional to its deformation moduli. These showed that coal ash is effective yet economic for hardening marine soil.

MEASURE: A SenseHat Smart Home Measuring System

Electrical and Electronic Engineering, The 2nd Engineering InnoShow / By

This project fully utilises the sensors on SenseHat to build a SenseHat smart home measuring System MEASURE. There are three functionalities provided by MEASURE: Level meter, Compass, and HomeKit Integration. Level meter can detect if a line is horizontal or if a surface is flat, and a compass can calculate the degrees turned as well as finding correct directions. If not in use, MEASURE can be a perfect HomeKit accessory that reports readings to your device. So MEASURE is a smart tool that can detect temperature and humidity right at your mobile and help determine positions for furniture placement. It can also provide angle guidance for homemade DIY stuff, and assist you in many other areas.

WeMake

Industrial and Manufacturing Systems Engineering, The 2nd Engineering InnoShow / By

WeMake provides four major services, which include customized dolls, pattern engraved phone glass film, customized accessories and print whatever you want. WeMake has implemented four advanced technologies to explore new business opportunities and attract customers. They are 3D scanning, 3D printing, augmented reality and cloud computing with the usage of mobile devices. First, customers would select the services and upload photo to the WeMake website. With the augmented reality technology, a preview of the product could be provided for customers. Once customers are satisfied with the preview, WeMake would print the product and deliver the finished product to customers. WeMake would always follow our mission: Whatever it takes, WeMake.

Design, Build & Fly 2020 team 3

Mechanical Engineering, The 2nd Engineering InnoShow / By

With the ever-growing demand for air cargo capacity comes the pursuit for cargo aircraft that combine a large payload with optimum efficiency. The Design, Build and Fly team set out to meet this challenge by creating a radio-controlled model airplane, to compete in the Payload Challenge organized by the British Model Flying Association (BMFA). The process involved careful research into aeronautical engineering theories and creative solutions. The effectiveness of the design was proved in test flights by two fully functional prototypes. Various issues were identified during the trials, carefully examined, and subsequently addressed in an iterative manner. The team has continuously implemented modifications to the design, in an effort to produce the model plane that would carry the target payload with the highest efficiency attainable, and the results will hopefully provide useful insights for future model builders and aircraft engineers alike.

Design, Build & Fly 2020 team 1

Mechanical Engineering, The 2nd Engineering InnoShow / By

Design, Build, Fly is a project for students to design and manufacture an airplane. Our team aims at producing a radio-controlled fixed-wing aircraft that conveys a predefined liquid payload in a flight circuit. This is to demonstrate its payload carrying capability with the lightest airframe. Through this project, students could apply technical and interpersonal skills to building an airplane with unconventional configurations.

Automatic Chair Parking System

Mechanical Engineering, The 2nd Engineering InnoShow / By

The Automatic Chair Parking System aims to provide a smart solution in classroom and
other similar environment by helping to move and arrange chairs, while reducing the risk of occupational injuries and potential dangers related to the repetitive works. This can also reduce the reliance on labor force and ultimately improve the efficiency. The system therefore is designed to autonomously transport chairs to the designated parking area with minimal human control.
