Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If manual power supply control is used, then the device structure remains simple, but unnecessary power consumption occurs and safety risks arise
Solution Approach 1:
The electronic device automatically controls its own power supply based on touch detection. The sensing module detects user touch and the power supply module automatically connects or disconnects power, eliminating the need for manual intervention and preventing unnecessary power consumption when the device is not in use.
Solution Approach 2:
The patent replaces manual mechanical power switching with an automated sensing and control system. The sensing module detects touch through electrical or capacitive changes, and the power supply module responds automatically, substituting the mechanical manual switch with an intelligent automated system.
2Reliability
If automatic touch sensing is implemented, then power consumption is reduced and safety is improved, but the device complexity increases
Solution Approach 1:
The control system is divided into distinct functional modules: a sensing module for detecting touch, a determination module for processing the touch signal, and a power supply module for executing power control. This segmentation allows each module to perform its specific function independently, improving reliability while managing complexity through modular design.
Solution Approach 2:
The determination module acts as an intermediary between the sensing module and the power supply module. It processes the raw touch signal and generates appropriate control signals, ensuring that power is only supplied when intentional touch is detected, thereby enhancing safety while maintaining a manageable system architecture.
3Ease of operation
If remote control operation is used, then user convenience is improved, but accidental activation and power consumption increase
Solution Approach 1:
The sensing module continuously monitors for touch before power activation occurs. By detecting touch in advance and requiring confirmation through the determination module, the system prevents accidental activation while maintaining ease of operation through intuitive touch-based control.
