Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector modules face challenges in absorbing displacement between the connection target instrument and the connector, leading to durability issues and impaired high-frequency propagation performance due to inadequate alignment and impedance matching.
Innovation Solution
A shield member with annularly arranged first and second elastic portions, defined by slits, allows elastic deformation for shock absorption and maintains electric connection, featuring curved parts and slit widths optimized for stable contact and impedance characteristics, integrated with a conductive tubular shell and shield cover for enhanced durability and shielding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible thin film member is used to fill the gap between the connector and the case for displacement absorption, then displacement absorption capability is improved, but the strength of the film member becomes problematic
Solution Approach 1:
The shield member is divided into multiple elastic portions (first elastic portions at the inner circumferential part and second elastic portions at the outer circumferential part) separated by slits. This segmentation allows each portion to independently deform and absorb displacement while maintaining overall structural strength, resolving the contradiction between flexibility for displacement absorption and structural strength.
Solution Approach 2:
The patent replaces the flexible thin film member with elastic portions made of conductive material that can be integrally formed with the shield member. This eliminates the need for a separate weak film member while providing both displacement absorption and sufficient strength through the elastic deformation capability of the slitted structure.
2Adaptability or versatility
If a movable tubular shell is used to absorb displacement, then displacement absorption is improved, but the shell repeatedly contacts the outer shell due to vibration causing durability problems
Solution Approach 1:
The elastic portions are designed with curved parts that provide beforehand cushioning against displacement and vibration. The curved geometry allows the elastic portions to deform in advance and absorb shock, preventing repeated contact and impact between the shield member and surrounding structures, thereby improving durability under vibrational conditions.
Solution Approach 2:
The patent uses elastic portions with curved parts that function as flexible elements within the rigid shield member structure. These flexible portions can deform to absorb displacement and vibration while maintaining electrical connection, eliminating the need for a completely movable tubular shell and thus preventing durability issues from repeated contact.
3Adaptability or versatility
If a movable tubular shell is used for displacement absorption, then alignment flexibility is improved, but the distance between the shell and outer shell cannot be maintained affecting impedance matching
Solution Approach 1:
The elastic portions are designed to dynamically adjust to displacement while maintaining a predetermined distance through their elastic deformation capability. The curved parts of the elastic portions allow them to flex and adapt to misalignment, yet their elastic nature ensures they return to and maintain the designed distance from the outer circumferential surface, preserving impedance matching characteristics.
Solution Approach 2:
The patent changes the physical state of the shield member by introducing elastic portions with curved parts that can alter their shape through elastic deformation. This allows the structure to adapt to displacement (improving alignment flexibility) while the elastic recovery force maintains the critical distance parameter for impedance matching, resolving the contradiction between flexibility and precision.
