Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface mounting type non-reciprocal circuit elements, such as circulators and isolators, are prone to deformation during mounting and manufacturing, leading to high process failure rates due to mechanical weakness and instability, especially when using non-conductive aligning frames made of plastic, which are vulnerable to external forces and difficult to fix securely.
Innovation Solution
A non-reciprocal element with a housing and frame structure featuring conductive pins and a H-beam shaped reinforcement, where the frame is made of synthetic resin and integrated with a ring-shaped body, fence portions, supporting portions, and leg portions to provide structural support and alignment, ensuring the conductive pins and frame components are securely coupled to the housing, preventing vertical movement and enhancing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-conductive aligning frame made of plastic is used, then manufacturing costs are reduced and ease of manufacture is improved, but the frame becomes mechanically weak and vulnerable to external forces, leading to deformation during mounting and manufacturing
Solution Approach 1:
The patent applies composite materials by combining synthetic resin (non-conductive material) with metal reinforcement ribs. The synthetic resin provides cost-effectiveness and electrical insulation, while the metal ribs embedded within provide enhanced mechanical strength and resistance to deformation. This composite structure resolves the contradiction between ease of manufacture and strength.
2Ease of manufacture
If a non-conductive aligning frame made of plastic is used, then manufacturing costs are reduced, but the frame becomes vulnerable to external forces and difficult to fix securely, leading to high process failure rates
Solution Approach 1:
The synthetic resin frame with embedded metal reinforcement ribs creates a composite structure that maintains cost-effectiveness while significantly improving reliability. The metal ribs prevent deformation under external forces during mounting and manufacturing, reducing process failure rates, while the synthetic resin maintains electrical insulation properties.
Solution Approach 2:
The H-beam shaped reinforcement structure with curved or angled elements provides geometric strength to the frame. The specific geometric configuration of the reinforcement ribs distributes mechanical stresses more effectively, enhancing the frame's ability to resist deformation and remain securely fixed during mounting operations.
3Ease of manufacture
If the frame is made of synthetic resin, then electrical insulation is maintained and manufacturing costs are reduced, but structural integrity and alignment stability may be compromised
Solution Approach 1:
The patent uses composite materials by embedding metal reinforcement ribs within the synthetic resin frame. The synthetic resin provides electrical insulation and cost-effectiveness, while the metal ribs provide structural integrity and alignment stability. This composite approach resolves the contradiction between manufacturing cost and alignment stability.
