Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional socket structure is used without detection functions, then the device structure remains simple, but exposed electrodes create electric shock risks and require safety certifications
Solution Approach 1:
The sensor detects object insertion into the socket before power is supplied, and the processor preemptively controls the switch to block current until proper insertion is confirmed. This preliminary detection and control action prevents electric shock risks before they can occur, resolving the safety concern without requiring complex additional safety mechanisms.
Solution Approach 2:
A sensor is introduced as an intermediary component between the socket and the power supply control system. The sensor detects whether an object is properly inserted and transmits this information to the processor, which then controls the switch. This intermediary detection mechanism enables safe power control while maintaining relatively simple device structure.
2Productivity
If power is continuously supplied to the socket, then the lighting function operates without interruption, but electric shock risks increase when lamps are detached
Solution Approach 1:
The sensor continuously monitors the socket insertion state and provides feedback to the processor. Based on this feedback, the processor dynamically adjusts the switch control - maintaining power supply when lamps are properly inserted and blocking power when lamps are detached or improperly inserted. This feedback mechanism resolves the contradiction by enabling continuous lighting operation under safe conditions while preventing electric shock risks.
Solution Approach 2:
The power supply state is made dynamic rather than static. The switch control changes based on real-time sensor detection results - the system transitions between power-on and power-off states according to lamp insertion status. This dynamic control enables the lighting function to operate continuously when needed while automatically preventing electric shock risks when lamps are detached.
3Ease of operation
If the socket structure exposes electrodes for easy lamp insertion, then ease of operation is improved, but safety risks increase due to exposed conductive parts
Solution Approach 1:
The sensor performs preliminary detection to confirm proper lamp insertion before the processor enables power supply through the switch. This preliminary action sequence maintains easy lamp insertion operation while preventing electric shock risks by ensuring power is only supplied after safe insertion is verified.
Solution Approach 2:
The sensor acts as an intermediary between the mechanically simple socket structure and the power supply system. It detects whether the lamp is properly inserted and communicates this status to the processor, which then controls power supply. This intermediary enables the socket to maintain its simple, easy-to-use structure while incorporating safety functionality.
