- Multi source heat pump for geoexchange systems (GXS)
- With the use and effectiveness of conventional heat pumps decreasing drastically in colder climate regions, geo-exchange systems have become the solution to allow heat pumps to still be operable in these colder regions. However, with the high costs of installation required for deep-well heat exchangers and horizontal-trench heat exchangers, and the high cost of land in high-density urban/suburban areas, their adoption is still small. For this reason, this project aims to increase the energy density of geo-exchange systems so that high installation costs are not required, and large land requirements become non-existent.

- Remote torque and speed data logger
- Baja SAE is an intercollegiate design competition hosted by SAE International, previously known as the Society of Automotive Engineers. At each event, more than 100 teams compete to design, build, and race light off-road vehicles. The British Columbia Institute of Technology is represented by its SAE-affiliated team, BCIT Racing, which has competed in four SAE events since 2015, and is in the early stages of designing and building a third-generation race vehicle. This paper describes the design, function and use of a wireless torque and rotation data logger device, which attaches to a vehicle’s drive axle for the purpose of observing drivetrain loads. The project was proposed by BCIT faculty member Adam Marciniak, in his role as BCIT Racing’s faculty supervisor. Upon completion, the data logger prototype will be used by BCIT Racing to determine peak force loads in the gearbox and drivetrain of the team’s Baja SAE race vehicle. This data will be used during the design of the team’s third-generation vehicle. The data logger project can be divided into three functional components: the housing, electronics, and software. The housing provides protection for sensitive electronics and sensors, and the software is used to gather sensor data and transmit it to a mobile phone application. At the time of this report, all sensors have been validated, and data is being successfully captured and stored. Recommendations for future work will be included in the report conclusions.

- Rexroth Bosch two axis servo trainer
- This document is a final report on the fourth-year mechanical engineering Capstone project: Two-Axis Servo Trainer/Bolt Tightener. This report covers the project background, current status, theory, activities, results, and conclusions. The project was sponsored by Rexroth Bosch who provided the opportunity to two BCIT fourth-year mechanical Capstone groups. The project was to create a physical servo motor trainer for learning employees and clients. The mechanism must be based on a commonly automated industry task, require position, velocity, and torque control, and 2-axis synchronization.

- Skateboard truck testing device
- Skateboard trucks are one of the three major components that, when assembled together, make up a skateboard along with the skateboard deck and wheels. The truck connects the deck to the wheels and translates the tilting motion of the deck to a turning motion of the truck to cause a turning response. As such, there is a relationship between how much the deck tilts to how much the trucks turn. Furthermore, the truck itself can come in varying sizes and configurations. The axle length, hardness of the bushings used and the angle that the truck sits on relative to the deck all can vary to provide a different feel and response for the rider of the skateboard. Although skateboards have been used since the early 1960’s, no device has been created to quantify the feel that skateboard riders feel with varying configurations of the truck. The purpose of this device is to provide quantitative data and results for each truck configuration tested so that the response of differing setups can be compared and provide valuable results for either riders or companies that design skateboard trucks.

- Truck bed bike rack
- McMillian’s Bike Co. contracted Wix Design Ltd. to design and prototype a bike rack situated in the bed of a truck. After doing a survey of their customers, McMillian’s Bike Co. found that customers were not satisfied with the current products in the market for transporting bicycles and believes there is a unique product development opportunity. The objectives that McMillian’s Bike Co. aim to fulfill is that the product be modular, compact, easy to use/install, versatile, affordable and secure. In terms of compactness the product should be able to hold at least four bikes with the potential of holding up to five. The product should be versatile in terms of securing different types of bikes that can range from BMX bikes to large mountain bikes. The product should be able to be broken down into modular units so that one can choose how many bikes can be attached to the rack. The design team from Wix Design Ltd. set out to design a product that would meet these criteria.
