Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrared sensors are used for detecting usage status, then the headset can detect wearing and non-wearing states, but the detection accuracy deteriorates due to false detection and insensitivity to other statuses
Solution Approach 1:
The patent changes the detection parameter from infrared radiation detection to structural deformation detection. The sensor circuit detects physical deformation of the headset structure when worn, providing more reliable and versatile status detection across multiple states including wearing, non-wearing, open, and stretch states, thereby resolving the contradiction between detection accuracy and status coverage
Solution Approach 2:
The patent replaces the optical/infrared detection system with a mechanical deformation detection system. The sensor circuit measures physical structural changes of the headset rather than infrared radiation, eliminating false detection issues and enabling accurate detection of various usage statuses through mechanical state changes
2Device complexity
If fixed threshold values are used for usage status determination, then the control logic is simple, but the detection accuracy deteriorates when user needs vary
Solution Approach 1:
The patent implements dynamic threshold adjustment where the secondary processor circuit adaptively changes threshold values based on detected usage status. This allows the system to maintain simple control logic structure while achieving high detection precision by adjusting thresholds according to actual usage conditions, resolving the contradiction between simplicity and precision
3Speed
If the primary processor circuit remains active for real-time control, then the response speed is fast, but the energy consumption increases
Solution Approach 1:
The patent segments the processor functions into two parts: a secondary processor circuit that continuously monitors sensor data with low power consumption, and a primary processor circuit that performs comprehensive control only when needed. This segmentation enables fast response through the always-active secondary processor while reducing overall energy consumption by keeping the primary processor in sleep mode during normal operation
Solution Approach 2:
The secondary processor circuit acts as an intermediary between the sensor circuit and the primary processor circuit. It pre-processes sensor data, determines usage status, and only wakes up the primary processor when actual control action is needed, thereby maintaining fast response capability while minimizing energy consumption of the main processing unit
