Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If discrete graphics processing units are used to improve graphics quality, then processing power and graphics quality are improved, but power consumption increases and operational duration is reduced
Solution Approach 1:
The system separates graphics processing functions into discrete GPU components that can be independently managed and powered, allowing the computing device to allocate power resources selectively to maintain high graphics performance while managing overall power consumption for extended operational duration
Solution Approach 2:
The computing device is designed to perform multiple functions including general computing tasks and intensive graphics processing, with the discrete GPU providing specialized graphics acceleration that enables high-performance VR/AR rendering while the system manages power distribution to balance performance and operational duration
2Power
If discrete graphics processing units are used to improve graphics quality, then graphics quality is improved, but heat generation increases and thermal management becomes difficult
Solution Approach 1:
The discrete GPU generates heat that is extracted and directed away from the user's body through dedicated airflow channels in the head-mounted display, separating the heat source from the user contact areas and enabling sustained high-performance graphics processing without compromising user comfort
Solution Approach 2:
The system uses airflow channels and ventilation pathways to actively manage thermal dissipation, directing cool air over heated components and exhausting warm air away from the user, enabling effective thermal management for high-performance discrete graphics processing in a compact wearable form factor
3Reliability
If wired connections are used to connect computing device to display device, then signal transmission is stable, but user movement is restricted and portability is reduced
Solution Approach 1:
The system replaces mechanical wired connections with wireless communication technologies, eliminating physical cables that would restrict user movement while maintaining reliable signal transmission between the computing device and display device through wireless data and power transmission protocols
