Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a currently used switch is assembled in a connector for high voltage direct current power supply, then the connector structure can be simplified, but safety and reliability are not assured
Solution Approach 1:
The patent changes the operational parameters of the switch by introducing a sliding mechanism that controls contact pressure and engagement timing. The sliding operation allows gradual contact establishment and separation, controlling arc generation and ensuring reliable operation at high voltages up to 400V DC, thereby maintaining safety without excessive structural complexity.
2Reliability
If a connector is designed for high voltage direct current power supply, then safety and reliability are improved, but the connector cannot be used with currently used commercial power sources
Solution Approach 1:
The connector design incorporates a universal sliding switch mechanism that can handle both high voltage direct current (up to 400V DC) and conventional alternating current (100V AC) power sources. The same structural design with sliding contacts and arc control features provides safety and reliability across different power source types and voltage levels, eliminating the need for separate connector designs.
3Loss of energy
If high voltage electric power is used in information apparatus, then power loss is reduced, but operator safety is compromised
Solution Approach 1:
The sliding switch mechanism acts as an intermediary control element between the operator and the high voltage circuit. The sliding action provides controlled, gradual contact establishment and separation, minimizing arc generation and electromagnetic interference. This intermediary mechanism allows safe operator interaction with high voltage systems while maintaining the energy efficiency benefits of high voltage power supply.
