Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printed board connectors face difficulties in ensuring accurate positioning and secure assembly with circuit boards due to reacting forces that misalign signal modules and metal shielding devices, making them inconvenient to use.
Innovation Solution
The design incorporates an insulating casing with a rib that guides and positions signal modules and metal shielding elements, enhancing the assembly strength by forming receiving spaces and extending insulating shielding walls to securely mount these components, which are then wedged to prevent signal disturbances and improve connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If signal modules and metal shielding devices are received inside the insulating casing without additional positioning structures, then the device complexity is reduced, but the manufacturing precision and positioning accuracy deteriorate due to reacting forces during assembly
Solution Approach 1:
The insulating casing is segmented into multiple receiving spaces by adding ribs, with each space dedicated to holding specific signal modules or metal shielding devices. This segmentation provides individual positioning zones that maintain manufacturing precision while keeping the overall structure manageable and not excessively complex.
Solution Approach 2:
Ribs are added to the insulating casing to create three-dimensional positioning structures. These ribs extend into the receiving spaces from multiple directions, providing multi-dimensional constraints that prevent movement of signal modules and metal shielding devices during assembly, thereby improving positioning accuracy without significantly increasing device complexity.
2Ease of manufacture
If signal modules and metal shielding devices are freely positioned in the insulating casing, then the ease of manufacture is improved, but the reliability deteriorates due to misalignment caused by reacting forces during pressing
Solution Approach 1:
The ribs are pre-formed in the insulating casing to create positioning structures before assembly. These ribs establish predetermined receiving spaces that guide and constrain signal modules and metal shielding devices into correct positions during the pressing operation, ensuring reliable alignment while maintaining ease of manufacture through a single-mold injection process.
Solution Approach 2:
The ribs act as intermediary structures between the insulating casing and the signal modules/metal shielding devices. They mediate the interaction by providing physical guidance and constraint, ensuring that reacting forces during pressing do not cause misalignment, thereby improving connection stability without complicating the assembly process.
3Device complexity
If the insulating casing lacks internal positioning structures, then the device complexity is reduced, but the strength of the assembly with the circuit board deteriorates due to misalignment
Solution Approach 1:
The insulating casing is divided into multiple receiving spaces by ribs, creating segmented zones that securely hold signal modules and metal shielding devices. This segmentation provides stable positioning that enhances assembly strength with the circuit board while maintaining a relatively simple single-piece casing structure without additional fastening components.
Solution Approach 2:
The insulating casing is formed as a composite structure combining the base casing material with integrated rib features. These ribs are molded as part of the insulating casing material, creating a composite positioning system that enhances assembly strength and stability without requiring separate components or increasing overall device complexity.
