Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external connectors and cables are used for data communication, then data transmission capability is achieved, but ease of operation deteriorates due to physical mating and de-mating requirements
Solution Approach 1:
The patent merges the connector and cable functions into an integrated hot shoe interface system. The contact pads on the hot shoe directly couple with contact pins on the mounting assembly, eliminating the need for separate external connectors and cables. This integration allows for one-handed connection and disconnection while maintaining high-speed data transmission capability.
2Ease of operation
If traditional hot shoe interfaces are used, then ease of connection is achieved, but data transmission capability deteriorates due to limited electrical coupling
Solution Approach 1:
The patent makes the hot shoe interface universal by enabling it to perform multiple functions simultaneously. The interface not only provides mechanical attachment and power transmission but also supports high-speed data communication through multiple contact pads. This multi-functionality allows a single interface to replace traditional separate connections for power and data.
Solution Approach 2:
The patent changes the electrical parameters of the hot shoe interface by implementing multiple contact pads with different electrical characteristics. The interface includes contact pads configured for high-speed data transmission with controlled impedance, transforming the traditional hot shoe from a simple power connection to a high-performance electrical interface capable of supporting modern data transmission requirements.
3Speed
If high speed data transmission is implemented through multiple contact pads, then data transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the electrical interface into multiple dedicated contact pads, each optimized for specific functions. The hot shoe includes contact pads for power, ground, and high-speed data transmission, with the data contacts further divided into differential pairs. This segmentation allows each contact to be optimized for its specific function while maintaining an overall simple interface structure.
