Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power source connectors and signal connectors are integrated together, then operation convenience is improved, but signal stability deteriorates due to high-power load current break impacting signal communication
Solution Approach 1:
The patent segments the connector into separate power source connectors and signal connectors, with distinct ground lines for each type. This segmentation allows independent ground paths that prevent high-power current interruptions from affecting signal communication, thereby maintaining signal stability while keeping both connector types integrated in one device.
Solution Approach 2:
The patent applies local quality by providing separate ground lines specifically for power source connectors and signal connectors. This localized differentiation ensures that each type of connector has its own dedicated ground path, preventing interference between power and signal circuits while maintaining overall integration.
2Device complexity
If rigid connection plug is used to connect power source and communication, then connection simplicity is improved, but harmful factors worsen due to spark generation damaging connectors and communication circuits
Solution Approach 1:
The patent implements preliminary action by establishing a specific connection sequence where the ground line connects first before the power line during the plugging process. This preliminary grounding prevents spark generation by providing a safe discharge path for any accumulated charge before power connection occurs, thereby protecting connectors and communication circuits from damage.
Solution Approach 2:
The ground line acts as an intermediary element that mediates between the power source and communication circuits. By connecting the ground line first, it provides a reference potential and safe discharge path that prevents direct spark generation between power and signal lines, thereby protecting the system from harmful effects.
3Object-affected harmful factors
If limit switch mechanism is used to avoid spark, then spark prevention is improved, but structure stability deteriorates due to long-term operation making structure loose and unstable
Solution Approach 1:
The patent replaces the mechanical limit switch system with an electrical connection sequence control mechanism. Instead of using a mechanical switch that opens and closes based on plug insertion position, the patent uses the inherent electrical properties of the ground line to automatically prevent sparks through proper connection sequencing, thereby eliminating mechanical wear and structural instability.
Solution Approach 2:
The ground line performs a dual function: it serves as both the reference potential for signal communication and the protective element that prevents spark generation. By connecting the ground line first, the system automatically protects itself from sparks without requiring additional mechanical switching mechanisms, thereby improving structural stability.
