Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality glasses are designed for entertainment purposes only, then they can focus on user experience and gaming activities, but they fail to meet the specific needs of industrial environments such as positioning accuracy and prolonged use
Solution Approach 1:
The system is divided into a head-mounted display device worn by the user and a separate back-mounted device containing the power supply and computing circuit. This segmentation allows the head-mounted portion to be lightweight and focused on display functions, while the back-mounted portion provides substantial power and processing capabilities, enabling both entertainment and industrial applications with high reliability
Solution Approach 2:
The head-mounted display device incorporates multiple sensors (time of flight sensor, optical sensors, inertial measurement unit) that can serve both entertainment functions (tracking user movement for gaming) and industrial functions (positioning accuracy, object detection, environment mapping). The system can adapt to different environments through software configuration rather than requiring hardware changes
2Measurement precision
If the head-mounted display device includes multiple sensors and processing units for industrial applications, then positioning accuracy and object detection improve, but the weight and complexity of the device increase
Solution Approach 1:
Complex components including the power supply module and computing circuit are separated into a back-mounted device, while the head-mounted display device contains only the essential sensors and display components. This reduces the weight and complexity of the head-mounted portion while maintaining high measurement precision through the distributed sensor array and external computing power
Solution Approach 2:
The computing circuit in the back-mounted device acts as an intermediary that processes data from multiple sensors (time of flight, optical sensors, inertial measurement unit) to compute positioning accuracy and perform object detection. This external processing unit reduces the computational burden on the head-mounted device while maintaining high measurement precision
3Duration of action of moving object
If a hot pluggable power supply is used in the back-mounted device, then prolonged usability is achieved, but the device requires additional connection interfaces and power management circuitry
Solution Approach 1:
The power supply is separated into a removable battery pack in the back-mounted device that can be independently replaced. This allows the power management system to be simplified into modular components: a standard power interface in the head-mounted device and a replaceable power source in the back-mounted device, reducing overall system complexity while enabling prolonged usability through hot-swappable batteries
