Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the width of terminals is increased to reduce transmission oscillation, then high-frequency signal transmission stability is improved, but the width available for assembly with the floating housing is reduced, increasing capacitance and destabilizing signal transmission
Solution Approach 1:
The terminal is divided into multiple sections: a first section with increased width for signal transmission stability, and a second section with reduced width for assembly with the floating housing. This segmentation allows each section to optimize for its specific function, resolving the contradiction between signal stability and assembly feasibility.
Solution Approach 2:
Different sections of the terminal have different width characteristics tailored to their specific functional requirements. The first section has increased width locally to reduce transmission oscillation, while the second section has reduced width locally to facilitate assembly, creating optimal local conditions for each function.
2Object-affected harmful factors
If the width of terminals is increased to enlarge cross-sectional area, then transmission oscillation is reduced, but the assembly width with floating housing must be reduced, increasing capacitance
Solution Approach 1:
The terminal structure is segmented into distinct width zones: an enlarged cross-sectional area section for reducing transmission oscillation, and a reduced width section for controlling capacitance during assembly. This allows the harmful oscillation to be countered while maintaining reliable signal transmission.
Solution Approach 2:
The terminal width variation occurs along the longitudinal dimension rather than uniformly across the cross-section. This dimensional approach allows the terminal to have both enlarged and reduced width sections, enabling simultaneous optimization for oscillation reduction and capacitance control.
3Ease of manufacture
If terminals are in a suspended state without contact with housing, then assembly is simplified, but transmission oscillation increases significantly
Solution Approach 1:
The terminal contact structure is segmented into a suspended section for assembly simplicity and a contact section for oscillation reduction. The contact section specifically engages with the housing to provide stabilization without complicating the overall assembly process.
Solution Approach 2:
The terminal acts as an intermediary element that transitions from a fully suspended state to a partially contacted state. The contact portion serves as a mediator between the suspended terminal structure and the housing, providing the necessary mechanical coupling to reduce oscillation while maintaining assembly simplicity.
