Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in achieving miniaturization of connectors while maintaining manufacturing convenience and electrical connection reliability, particularly in B2B connectors, where reduced contact spacing complicates soldering and increases the risk of electrical interference.
Innovation Solution
A connector design featuring a plug and receptacle with insulators and support walls that maintain contact spacing, using alternating contact orientations and insulating materials to prevent electrical interference, and incorporating through-holes for easy inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between contacts is reduced to achieve miniaturization, then the connector size is reduced, but the soldering difficulty increases and electrical interference risk increases
Solution Approach 1:
The connector is divided into a plug and receptacle with separate contact arrangements. The plug contacts and receptacle contacts are segmented into distinct groups with insulating walls between them, allowing independent positioning and soldering of each contact group while maintaining overall miniaturization.
Solution Approach 2:
Different regions of the connector have different contact densities and spacing. The insulating walls create local zones with specific electrical isolation properties, allowing contacts to be positioned closely where needed while maintaining adequate spacing and isolation in other areas through the insulating structures.
2Volume of moving object
If the distance between contacts is reduced to achieve miniaturization, then the connector size is reduced, but electrical interference between contacts increases
Solution Approach 1:
Insulating walls and support structures are introduced as intermediary elements between adjacent contacts. These intermediaries provide physical separation and electrical isolation, preventing direct electrical interference between closely spaced contacts while allowing the overall connector size to remain small.
Solution Approach 2:
The connector structure incorporates self-isolating features where the insulating walls and support walls automatically provide electrical isolation between contacts. The design ensures that each contact group is self-contained with its own isolation barriers, eliminating the need for additional external shielding or isolation measures.
3Ease of manufacture
If alternating contact orientations are used to improve manufacturing, then manufacturing convenience is improved, but structural complexity increases
Solution Approach 1:
Contacts are arranged in alternating orientations (e.g., some contacts extend in one direction while adjacent contacts extend in a perpendicular direction). This asymmetric arrangement optimizes the use of available space and allows for more efficient soldering access from different sides, improving manufacturing convenience despite the increased structural complexity.
