Bracket With Cut-Outs For Single Pin Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting apparatuses for lifting/lowering devices in confined spaces are complex, costly, and lack safety compliance, often requiring multiple pins for installation, which can lead to inefficiencies and increased risk during emergency operations.
Innovation Solution
A bracket and lifting/lowering device assembly that utilizes a single support member pin for mounting, featuring a body with cut-outs for secure engagement, reducing the need for additional pins and enhancing safety through a telescopic support member and shaped ends for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple pins are used to mount the lifting/lowering device to the support member, then the mounting security is improved, but the device complexity and installation time increase
Solution Approach 1:
The patent combines the functions of multiple pins into a single integrated support member pin. The pin is designed with a head that engages with a recess in the bracket and a shaft that passes through the support member, consolidating what would traditionally require multiple separate fastening elements into one component that simultaneously provides both mounting and securing functions.
Solution Approach 2:
The support member pin serves multiple functions: it acts as both the primary mounting element and the securing element, eliminating the need for separate pins. The pin's design allows it to engage with the bracket's recess while also passing through the support member's mounting hole, making it a multi-functional fastening component that simplifies the overall assembly.
2Reliability
If multiple pins are used for mounting, then the mounting security is improved, but the installation time increases
Solution Approach 1:
The patent combines the functions of multiple pins into a single integrated support member pin. The pin is designed with a head that engages with a recess in the bracket and a shaft that passes through the support member, consolidating what would traditionally require multiple separate fastening elements into one component that simultaneously provides both mounting and securing functions.
Solution Approach 2:
The bracket is designed with a recess that is pre-configured to receive and guide the support member pin into its final position. This preliminary preparation of the mounting interface ensures that when the pin is inserted, it automatically engages correctly without requiring additional alignment steps or multiple fastening operations, thereby reducing installation time.
3Ease of operation
If a single pin is used for mounting, then the installation simplicity is improved, but the mounting security may be compromised
Solution Approach 1:
The support member pin and its engagement features are designed with asymmetric geometry. The pin has a head with a specific shape that fits into a corresponding asymmetric recess in the bracket, and the shaft portion has features that engage with the support member in a non-symmetric manner. This asymmetric design prevents accidental disengagement while maintaining simple installation, as the pin can only be inserted in the correct orientation and will lock into place securely.
Solution Approach 2:
The patent converts the potential weakness of using a single pin into a strength by designing the pin and its engagement features to maximize security. The asymmetric recess and pin geometry create a mechanical interlock that is more secure than traditional multi-pin arrangements, while the integrated design eliminates gaps or weak points that could arise from multiple separate fastening elements.
