Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection units with multiple components and bends are used, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functional components (contact elements, support sections, engagement sections, and housing) into a single integrated connection unit. The contact elements are directly formed with integrated support and engagement sections, eliminating the need for separate components and reducing assembly complexity while maintaining connection reliability.
Solution Approach 2:
The connection unit is designed with universal applicability through standardized engagement sections and contact elements that can connect various types of connection elements (busbars, flat contacts). The housing and contact elements provide multiple functions including electrical contact, mechanical support, positioning, and safety protection within a single device structure.
2Stability of the object's composition
If traditional connection units with fixed structures are used, then structural stability is improved, but adaptability to different connection elements decreases
Solution Approach 1:
The patent employs floatingly mounted contact elements that can move relative to the housing, allowing the connection unit to adapt to different connection element dimensions and insertion angles. The spring elements provide dynamic adjustment capability, enabling the rigid housing structure to accommodate variable connection elements while maintaining stable electrical contact.
Solution Approach 2:
The connection unit utilizes parameter changes in the form of adjustable contact pressure through spring elements and variable positioning of floating contact elements. This allows the same structural framework to maintain stable connections across different connection element types by dynamically adjusting contact parameters rather than requiring different fixed structures.
3Adaptability or versatility
If floating mounting of contact elements is used, then adaptability to different connection elements is improved, but device complexity increases
Solution Approach 1:
The patent segments the connection unit into a fixed housing structure and floating contact elements, allowing the complex adaptive function to be isolated to specific components. The spring elements and floating mounting mechanism are concentrated in discrete locations, simplifying the overall design while providing the necessary adaptability through localized dynamic components.
4Object-affected harmful factors
If finger protection elements are added for safety, then user safety is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The finger protection element is integrated with the contact elements, forming a unified safety component. The protection element is directly formed as part of the contact element structure, combining the electrical contact function and safety protection function into a single component, thereby reducing overall device complexity while maintaining user safety.
