Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In connector devices, reducing the size leads to narrower intervals between adaptors, which can result in reduced grounding performance due to potential differences between movable outer conductors.
Innovation Solution
A connector device with swingable movable terminal units connected via a resilient contact piece and a connecting member that ensures all movable outer conductors are at the same potential, preventing potential differences and enhancing grounding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the connector device is reduced, then the compactness is improved, but the grounding performance deteriorates due to potential differences between adjacent movable outer conductors
Solution Approach 1:
The patent applies the equipotentiality principle by electrically connecting all movable outer conductors to a common potential through the housing. The housing serves as a reference potential body that all movable outer conductors connect to, ensuring they maintain the same potential even when positioned closely together. This resolves the grounding performance issue while allowing compact device sizing.
Solution Approach 2:
The housing acts as an intermediary element that mediates the electrical connection between multiple movable outer conductors and the ground circuit. Instead of directly connecting adjacent movable outer conductors to each other, the housing serves as an intermediate connection point, ensuring equipotentiality while accommodating the compact arrangement of multiple conductors.
2Volume of moving object
If intervals between adaptors are narrowed to reduce device size, then the compactness is improved, but the electrical conductivity between movable outer conductors deteriorates
Solution Approach 1:
The housing serves as an intermediary that provides electrical connection between movable outer conductors spaced at narrow intervals. By connecting each movable outer conductor to the housing, the patent ensures electrical conductivity is maintained even when physical intervals between adaptors are reduced for compactness.
Solution Approach 2:
The patent establishes equipotentiality among all movable outer conductors by connecting them to the common reference potential of the housing. This ensures that even when intervals are narrowed, the electrical conductivity and potential equality are maintained through the common housing connection rather than requiring direct conductor-to-conductor connections.
