Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional soldering methods are used with metallic connectors, then electrical connection is achieved, but positioning precision deteriorates due to tolerance-related deviations in solder pads and protective sleeves
Solution Approach 1:
The patent introduces a tolerance compensation piece as an intermediary component between the protective sleeve and the circuit board. This piece absorbs and compensates for tolerance deviations, enabling precise positioning of solder terminal elements even when the protective sleeve has manufacturing tolerances. The intermediary layer decouples the tolerance accumulation chain, solving the contradiction between positioning precision and connection reliability.
Solution Approach 2:
The patent employs a horizontally deformable sheet metal component that can change its dimensional parameters (horizontal deformation) to compensate for tolerance deviations. By allowing the compensation piece to deform horizontally, it adapts to varying positions of solder terminal elements, maintaining precise alignment and reliable soldering connections despite initial tolerance variations.
2Adaptability or versatility
If multiple solder terminal elements are used in connectors, then electrical connectivity is improved, but positioning difficulty increases due to cumulative tolerance deviations
Solution Approach 1:
The tolerance compensation piece serves as a mediator that collectively manages the positioning of multiple solder terminal elements. Instead of each element independently suffering from tolerance accumulation, the compensation piece provides a unified reference framework that maintains relative positioning accuracy across all solder terminals, enabling multi-point electrical connectivity without cumulative positioning errors.
3Ease of operation
If a radially projecting tolerance compensation piece is used, then positioning facilitation is achieved, but radial deviation increases
Solution Approach 1:
The patent applies local quality by making the compensation piece horizontally deformable specifically in the regions where tolerance compensation is needed, while maintaining radial rigidity where structural stability is required. This localized differentiation allows the piece to facilitate positioning through horizontal deformation without increasing radial deviation, solving the contradiction between ease of operation and manufacturing precision.
