Terminal Locking Assembly With Elastic Catch Against Push-Up
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing locking mechanisms in terminal devices, relying solely on double-sided adhesive for bonding structural members, fail to effectively secure these components, leading to poor locking performance and reliability due to compression forces from sealing members, electrically conductive members, and grounding elastic sheets, which can cause structural members to be pushed up, affecting signal and sealing integrity.
Innovation Solution
A locking assembly with separable locking portions on the first and second structural members, including a lock hole and lock catch mechanism, and a lock hole component with an elastic member, which provides an inward force to secure the structural members and prevent them from being pushed up by compression forces, enhancing the locking performance and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If double-sided adhesive is used to bond structural members, then the bonding process is simple, but the locking performance is poor and structural members can be pushed up by compression forces
Solution Approach 1:
The bonding system is segmented into multiple functional components: double-sided adhesive for basic bonding and locking portions (with lock holes and lock catches) for enhanced mechanical interlocking. This segmentation allows each component to perform its specialized function, resolving the contradiction between simple bonding process and reliable locking performance.
Solution Approach 2:
The solution combines different bonding mechanisms into a composite system: chemical bonding via double-sided adhesive and mechanical bonding via locking portions. This composite approach integrates the simplicity of adhesive bonding with the reliability of mechanical interlocking, simultaneously achieving ease of manufacture and high reliability.
2Device complexity
If only double-sided adhesive is used for bonding, then the device structure is simple, but the locking capability is insufficient under compression forces
Solution Approach 1:
The bonding structure is divided into distributed locking portions spaced across the structural members, each providing localized mechanical interlocking. This segmentation enhances locking capability without requiring a completely complex overall structure, maintaining relative simplicity while improving strength.
Solution Approach 2:
Instead of uniformly strengthening the entire bonding structure, locking portions are strategically placed at critical locations where compression forces act on sealing members and electrically conductive members. This partial action approach provides sufficient locking capability where needed while avoiding unnecessary complexity elsewhere.
3Ease of operation
If structural members are loosely bonded, then assembly is easy, but sealing members and electrically conductive members cannot maintain proper compression
Solution Approach 1:
The locking portions with lock holes and lock catches are pre-configured on the structural members before assembly. During assembly, these pre-configured features automatically engage to provide immediate mechanical interlocking and proper compression, ensuring both ease of operation and reliability without requiring additional adjustment steps.

AI summary
A locking assembly includes a first structural member and a second structural member. The first structural member includes a first locking portion, and the second structural member includes a second locking portion. The second locking portion is separably locked with the first locking portion, to lock the first structural member with the second structural member and separate the first structural member from the second structural member.
