Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reduction in size of board-to-board (BTB) connectors in electronic devices compromises their structural strength, leading to assembly issues such as poor contact and reduced yield rates due to increased fragility.
Innovation Solution
A connector male plug design featuring a base with higher material strength than the supporting member, incorporating limiting holes and U-shaped connection terminals, embedded in a supporting member to enhance structural integrity while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the BTB connector is reduced to save installation space, then the installation space is saved, but the overall strength of the connector decreases
Solution Approach 1:
The patent employs composite materials by combining a metal base (providing strength) with a plastic supporting member (providing insulation and structural support). This allows the connector to maintain high strength despite reduced overall size, as the metal base provides structural integrity while the plastic component enables miniaturization and cost-effective manufacturing.
Solution Approach 2:
The connector is divided into distinct functional segments: a metal base for strength, a plastic supporting member for insulation and support, and embedded connection terminals for electrical connection. This segmentation allows each component to be optimized independently, enabling the overall connector to be small while maintaining necessary strength through the metal base.
2Volume of moving object
If the size of the BTB connector is reduced, then the installation space is saved, but the connector becomes easily damaged during assembly
Solution Approach 1:
The combination of metal base and plastic supporting member creates a composite structure where the metal provides inherent damage resistance during handling and assembly, while the plastic provides cushioning and insulation. This composite approach allows miniaturization without sacrificing reliability during the assembly process.
Solution Approach 2:
The plastic supporting member acts as a cushioning element that protects the fragile connection terminals during assembly operations. By embedding the terminals within the plastic support structure before assembly, the design provides beforehand protection against damage during the assembly process.
3Volume of moving object
If the size of the BTB connector is reduced, then the installation space is saved, but poor contact occurs
Solution Approach 1:
The metal base provides excellent electrical conductivity and structural stability for reliable contact, while the plastic supporting member maintains precise positioning of the connection terminals. This composite structure ensures that even in a miniaturized connector, the electrical contacts maintain high quality connection.
Solution Approach 2:
The connection terminals are locally optimized by embedding them in the plastic supporting member, which provides precise local positioning and support. This local quality enhancement ensures reliable contact at the critical interface while allowing the overall connector size to be reduced.
