Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent viewing parts are used in head mount devices, then visibility is improved, but moisture accumulation occurs due to humidity and breathing which obstructs the user's view
Solution Approach 1:
The heating element is activated in advance or continuously to maintain the viewing part temperature above the dew point, preventing moisture condensation before it can accumulate and obstruct the user's view
Solution Approach 2:
The temperature of the viewing part is changed by applying electrical heating, which alters the physical conditions for condensation and prevents moisture accumulation by maintaining the surface temperature above the dew point
2Object-affected harmful factors
If heating elements are added to prevent moisture, then moisture prevention is improved, but device complexity increases
Solution Approach 1:
A thin transparent heating element is integrated into the viewing part, maintaining optical clarity while providing heating functionality. The heating element is disposed between the user's face and the outer environment, preventing moisture accumulation without significantly increasing device complexity
Solution Approach 2:
The heating element serves multiple functions: preventing moisture condensation on the viewing part and potentially providing comfortable warmth for the user's face, thereby reducing overall device complexity through multi-functionality
3Ease of operation
If wireless power transmission is implemented, then ease of operation is improved, but reliability of power transmission in humid environments deteriorates
Solution Approach 1:
The heating function is extracted from the power management system and implemented as a separate transparent heating element with dedicated power supply, allowing independent control and optimization of both wireless power transmission and moisture prevention functions
Solution Approach 2:
The control circuit acts as an intermediary that coordinates between the wireless power transmission system and the heating element, ensuring reliable operation by managing power distribution and controlling heating based on humidity sensor feedback
