Resilient Bracket Pin Assembly for Multi-Shape Rack Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bracket pin assemblies lack a proper positioning device, causing the pin to shift or slide due to vibration, and cannot be connected to three different shapes of holes, such as square, circular, and other configurations, leading to instability and improper fitting.
Innovation Solution
A bracket pin assembly with a support plate, pins, and installation members that include resilient members to provide elastic force, allowing the pins to be securely connected to racks with various hole shapes by extending through different-sized windows and engaging sections, preventing inward retraction and ensuring firm installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional support bracket pin assembly is designed to be resiliently retractable, then the pin can be connected to square holes or circular holes of racks, but the pin may shift or slide due to vibration without a proper positioning device
Solution Approach 1:
The patent introduces a positioning device as an intermediary component between the resilient pin and the rack holes. This positioning device includes positioning protrusions on the pin that engage with corresponding positioning recesses in the rack, preventing lateral movement and rotation while allowing the resilient pin to maintain its elastic connection function. The positioning device mediates between the need for versatility in hole shape compatibility and the need for stability against vibration.
2Reliability
If conventional pin of bracket is designed for specific hole shapes, then it can be connected to certain rack configurations, but it cannot be connected to three different shapes of holes of racks
Solution Approach 1:
The patent designs the pin with a universal structure that can accommodate multiple hole shapes (square, circular, and other configurations). The pin includes a resilient body with a through-hole that can receive different types of fastening members, and the positioning device is designed with universal positioning features that work with various hole geometries. This multi-functional design allows the same pin assembly to provide reliable connections across different rack configurations without requiring shape-specific variants.
3Device complexity
If conventional pin assembly lacks positioning device, then the structure is simpler, but the pin shifts or slides due to vibration
Solution Approach 1:
The patent segments the pin assembly into distinct functional components: the resilient pin body, the positioning device, and the fastening member. The positioning device is designed as a separate, modular component that can be independently manufactured and assembled. This segmentation allows the positioning function to be added without fundamentally redesigning the entire pin assembly, maintaining relative structural simplicity while effectively preventing vibration-induced shifting through the dedicated positioning protrusions and recesses.

Function Achieved in This Case
The solution provides a stable and secure connection to racks with different hole shapes, preventing pin retraction and ensuring firm installation, addressing the instability issues of conventional pin assemblies.
Implementation Method 1
The at least one resilient member is located in the chamber of the base and provides elastic force to the first and second installation members

AI summary
A bracket pin assembly includes a support plate having an end plate which has at least one opening. The pin includes a base, a support member, a first installation member, a second installation member, and a resilient member. The base has a chamber and the support member is connected to the base. The first and second installation members respectively have a first engaging portion and a second engaging portion. The support member has an engaging section. The resilient member is located in the chamber of the base to bias the first and second installation members. When the installation members of the pin extend through the first installation holes of the first post, the first and second engaging portions are engaged with the engaging section of the support members to secure the first and second installation members relative to the support members.
