Memory Socket Cover Structure for Fool-Proof Member Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing memory socket fool-proof members wear out over time, leading to alignment issues between goldfingers on the memory module and pads inside the socket, causing poor contact, offset misalignment, or short circuits due to repeated insertion and removal of memory modules.
Innovation Solution
A memory socket protecting cover with a wear-resistant member is integrated into the memory socket assembly, featuring two lateral walls and a wear-resistant member that is wider than the fool-proof member but narrower than the concave, positioned to contact the memory module when inserted or removed, reducing wear on the fool-proof member and enhancing structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fool-proof member is used in the memory socket to prevent inverse insertion, then the memory socket provides orientation guidance, but the fool-proof member wears out over time due to repeated insertion and removal, causing alignment issues between goldfingers and pads
Solution Approach 1:
The patent introduces a wear-resistant member as an intermediary component between the memory module and the fool-proof member. This mediator absorbs the wear from repeated insertion and removal operations, protecting the fool-proof member from degradation while maintaining its orientation guidance function. The wear-resistant member is specifically designed to contact the memory module during insertion/removal, preventing direct contact between the module and the fool-proof member, thus resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent applies local quality by creating a specific region with enhanced wear resistance properties. The wear-resistant member is positioned precisely at the contact point where insertion and removal forces are applied, while the rest of the fool-proof member maintains its original properties for orientation guidance. This localized enhancement of wear resistance at the critical contact area allows the fool-proof member to continue providing orientation guidance without suffering from wear-induced alignment issues.
2Manufacturing precision
If the fool-proof member is made wider to improve contact stability, then the memory module alignment is improved, but the fool-proof member becomes more prone to wear and deformation
Solution Approach 1:
The wear-resistant member serves as a mediator that takes on the wear burden, allowing the fool-proof member to be optimized for alignment precision without compromising wear resistance. The intermediary component is specifically designed to contact the memory module first during insertion and removal, protecting the wider fool-proof member from direct contact and wear, thus maintaining both alignment precision and strength.
Solution Approach 2:
The patent effectively creates a composite structure by combining the fool-proof member (optimized for alignment and orientation) with the wear-resistant member (optimized for durability). This composite approach allows each component to be designed for its specific function - the fool-proof member provides precise alignment guidance while the wear-resistant member provides durability against repeated mechanical stress, resolving the contradiction between manufacturing precision and strength.
3Productivity
If the fool-proof member structure is simplified to reduce manufacturing cost, then the production efficiency increases, but the fool-proof member wears out faster leading to poor contact and short circuits
Solution Approach 1:
The patent segments the original fool-proof member structure into two separate components: the fool-proof member itself (for orientation guidance) and the wear-resistant member (for durability). This segmentation allows the fool-proof member to be manufactured simply and efficiently, while the wear-resistant member is added as a separate protective element. The segmentation resolves the contradiction by enabling simple manufacturing of the core component while adding wear protection through a separate, specialized component.
Solution Approach 2:
The wear-resistant member acts as an intermediary that protects the simplified fool-proof member structure from wear. By introducing this mediator, the patent allows the fool-proof member to maintain a simple, cost-effective design while the wear-resistant member absorbs the mechanical stress and wear, preventing contact reliability issues that would otherwise result from the simplified structure.

AI summary
A memory socket protecting cover (100) adapted to be assembled to a memory socket (30) which is adapted for a memory module to insert is provided. The memory module includes a fool-proof concave, and the memory socket includes a fool-proof member (32) corresponding to the fool-proof concave. The memory socket protecting cover includes two lateral walls (110) and a wear-resistant member (120). The two lateral walls are adapted to be disposed at two sides of the memory socket. The wear-resistant member is connected to the two lateral walls and adapted to be disposed on the fool-proof member. A width of the wear-resistant member is greater than or equal to a width of the fool-proof member and is smaller than a width of the fool-proof concave. When the memory module is inserted in or pulled from the memory socket, a wall of the memory module besides the fool-proof concave is adapted to contact the wear-resistant member.
