Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple capacitive sensors are used to detect wear status and user input, then detection reliability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines multiple capacitive sensors into a single integrated sensor unit located in the temple. This sensor unit simultaneously performs wear detection and user input detection functions, reducing the number of separate components while maintaining reliable detection capabilities through multi-functional design
Solution Approach 2:
The capacitive sensor in the temple is designed with multi-functionality, serving both as a wear detection sensor and as a user input sensor. This universal approach allows a single sensor to perform multiple detection tasks, reducing overall device complexity while maintaining comprehensive detection reliability
2Adaptability or versatility
If electronic components are placed in temples or frame structures, then functionality is improved, but aesthetics and space optimization are compromised
Solution Approach 1:
The patent nests electronic components within the temple structure, utilizing the existing spatial framework to house batteries, sensors, and control circuits. This nesting approach integrates electronics into the structural elements of the eyeglasses, maintaining aesthetic appearance while providing necessary functionality
Solution Approach 2:
The patent relocates electronic components from traditional frame locations to the temple dimension, utilizing the temple's structural space to house electronics. This dimensional relocation allows electronic functionality to be incorporated without compromising the aesthetic appearance of the front frame structure
3Reliability
If sensors continuously monitor wear status, then battery management is improved, but energy consumption increases
Solution Approach 1:
The capacitive sensor in the temple operates in a periodic monitoring manner, detecting wear status and user input actions at appropriate intervals rather than continuously. This periodic operation allows the system to maintain reliable battery management through wear detection while minimizing energy consumption by avoiding constant sensor activation
