Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bracket pin assemblies fail to securely connect to racks with different shapes of holes, leading to potential shifting or sliding due to vibration, and cannot be firmly connected to three different types of holes.
Innovation Solution
A bracket pin assembly featuring a support plate with a pin connected to a base, support member, and installation members with resilient members, allowing for secure engagement with various hole sizes through adjustable installation members and resilient forces, preventing inward retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional support bracket pin assembly is designed to be resiliently retractable to fit square holes or circular holes, then the bracket can be mounted to racks with different hole shapes, but the pin may shift or slide due to vibration because most prior arts lack a proper positioning device
Solution Approach 1:
The pin assembly is segmented into multiple functional components: a resilient member (spring) for adaptability, a positioning member with positioning protrusions for stability, and a retaining member for securing. This segmentation allows each component to perform its specific function - the spring provides resilient retraction for different hole shapes, while the positioning protrusions prevent shifting during vibration
Solution Approach 2:
The positioning member acts as an intermediary between the pin and the rack hole. Its positioning protrusions engage with the hole walls to prevent lateral movement and sliding during vibration, while the resilient member provides the necessary adaptability for different hole shapes. This intermediary structure resolves the contradiction between versatility and stability
2Device complexity
If a conventional pin assembly uses a simple resiliently retractable design, then the structure remains simple, but it cannot be firmly connected to three different shapes of holes of racks
Solution Approach 1:
The pin assembly is designed with multi-functionality to handle three different hole shapes. The resilient member provides resilient retraction, the positioning member provides lateral positioning, and the retaining member provides secure engagement. This combination of multiple functions in a single assembly achieves versatility for different hole shapes without requiring completely separate designs for each hole type
Solution Approach 2:
The resilient member (spring) introduces dynamic capability to the pin assembly, allowing it to adapt its shape and size to fit different hole configurations. The spring can compress and expand to accommodate variations in hole dimensions and shapes, enabling the same pin structure to work with three different hole types
3Device complexity
If a conventional pin assembly lacks a positioning device, then the structure remains simple, but the pin may shift or slide due to vibration
Solution Approach 1:
The positioning member with positioning protrusions serves as an intermediary that prevents lateral movement of the pin during vibration. These protrusions engage with the hole walls to provide lateral support and positioning, eliminating the shifting and sliding problems while maintaining relative structural simplicity
Solution Approach 2:
The positioning member provides preliminary anti-action against the harmful effect of vibration-induced movement. By pre-configuring the positioning protrusions to engage with the hole walls, the design proactively prevents lateral movement before vibration can cause shifting or sliding, rather than attempting to correct the problem after it occurs

AI summary
A bracket pin assembly includes a support plate (10) having an end plate (16) which has at least one opening (18). The pin (12) includes a base (22), a support member (24), a first installation member (26), a second installation member (28), and a resilient member (30). The base (22) has a chamber (32) and the support member (24) is connected to the base (22). The first and second installation members (26, 28) respectively have a first engaging portion (46a) and a second engaging portion (46b). The support member (24) has an engaging section (38). The resilient member (30) is located in the chamber (32) of the base (22) to bias the first and second installation members (26, 28). When the installation members (26, 28) of the pin (12) extend through the first installation holes (50) of the first post (48), the first and second engaging portions (46a, 46b) are engaged with the engaging section (38) of the support members (24) to secure the first and second installation members (26, 28) relative to the support members (24).
