Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contacts with resilient-tensioning means face challenges in maintaining consistent conduction due to varying cross-sections of the helical spring and misalignment issues between the coaxial stem and hyperboloid, affecting efficiency and mechanical reliability.
Innovation Solution
A contact design featuring a coaxial stem that interacts with a scored hyperboloid, where the container body incorporates a closing element and precise locating means, such as shoulders or constrictions, to ensure constant contact and alignment, preventing deformation and misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coaxial stem with a scored hyperboloid is used to ensure reliable conduction, then conduction reliability is improved, but alignment difficulty increases
Solution Approach 1:
The patent introduces a container body as an intermediary element that houses both the stem and the scored hyperboloid, pre-establishing their relative positions. This mediator structure eliminates the need for precise field alignment during assembly, as the container body itself ensures the correct spatial relationship between the stem and hyperboloid through its manufacturing process.
Solution Approach 2:
The container body is manufactured with pre-formed shoulders and constrictions that automatically position the stem and scored hyperboloid in their correct relative locations. This preliminary action of pre-positioning components during container manufacturing eliminates alignment difficulties that would otherwise occur during final assembly.
2Strength
If a helical spring is used as resilient-tensioning means, then mechanical resilience is improved, but conduction consistency deteriorates
Solution Approach 1:
The container body acts as an intermediary that provides a stable reference frame for the helical spring. By anchoring the spring between fixed shoulders within the rigid container structure, the system maintains consistent conduction geometry despite the spring's elastic deformation, as the container prevents lateral displacement and maintains proper alignment.
