Socket Display Board Stepped Engagement for Sleeve Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display boards for sockets without stepping inner holes cause the sleeve member to easily detach when disassembled, leading to unstable socket assembly and potential failure in function.
Innovation Solution
A display board with a stepped engagement portion featuring a large-diameter and small-diameter hole combination, where the stepped engagement portion is inserted into the positioning hole, ensuring secure assembly and easy disassembly of the socket, preventing the sleeve member from detaching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a socket with a sleeve member is assembled to a conventional display board, then the socket can be displayed and stored, but the sleeve member easily detaches when disassembled causing functional failure
Solution Approach 1:
The positioning hole is segmented into two distinct parts: a large-diameter hole for the stepped engagement portion and a small-diameter hole for the sleeve member. This segmentation allows the sleeve member to be retained during disassembly while still permitting easy removal of the socket body, resolving the contradiction between assembly stability and disassembly convenience.
Solution Approach 2:
Different regions of the positioning hole are given different diameters to serve different functions. The large-diameter hole provides secure engagement for the socket, while the small-diameter hole specifically retains the sleeve member. This local differentiation of structural properties solves the problem of sleeve member detachment during disassembly.
2Strength
If the sleeve member is overly engaged with the display board, then the socket can be securely assembled, but the sleeve member cannot be properly retained during disassembly
Solution Approach 1:
The engagement structure is segmented into two zones: the large-diameter hole provides strong engagement for the socket body, while the small-diameter hole provides retention for the sleeve member. This segmentation allows each component to be optimized for its specific function, ensuring both strength and reliability.
Solution Approach 2:
The small-diameter hole acts as an intermediary structure that specifically interacts with the sleeve member during disassembly. This intermediary feature ensures the sleeve member is retained while allowing the main socket assembly to be disassembled, resolving the contradiction between engagement strength and member retention.
3Device complexity
If a conventional engagement structure is used, then the display board structure is simple, but the socket assembly is unstable and prone to falling off
Solution Approach 1:
The positioning hole uses local quality differentiation with two distinct diameters. This simple modification to the hole structure provides enhanced socket assembly stability without significantly increasing overall device complexity. The stepped engagement portion similarly uses local geometry changes to improve stability.
Solution Approach 2:
The small-diameter hole is nested within or adjacent to the large-diameter hole, creating a compact dual-function positioning structure. This nesting approach maintains simplicity in the overall display board structure while providing the stability benefits of differentiated engagement zones.

AI summary
A display board for socket is provided, for assembling of at least one socket thereto. The socket includes a positioning hole including a large-diameter hole and a small-diameter hole. The display board includes a main body. At least one side of the main body is formed with an assembling portion. The assembling portion includes at least one stepped engagement portion protrudedly formed on a surface of the main body. The stepped engagement portion includes a large-diameter engagement portion and a small-diameter portion. The large-diameter engagement portion includes a first lateral surface, and the small-diameter portion includes a second lateral surface. When the stepped engagement portion is inserted in the positioning hole, the first lateral surface corresponds to and is tightly engaged with an inner wall of the large-diameter hole, and the second lateral surface corresponds to and is releasingly assembled within the small-diameter hole.
