Bracket and lifting/lowering device assembly
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 secure attachment, which can lead to installation delays and safety hazards during emergency operations.
Innovation Solution
A bracket and lifting/lowering device assembly that utilizes a single support member pin for attachment to a safety structure, featuring a cut-out with shaped ends to secure the pin and prevent disengagement, reducing the need for additional pins and enhancing safety compliance.
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 security and reliability of attachment 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 portion that engages the bracket and a shaft portion that inserts through the support member, eliminating the need for separate attachment pins while maintaining secure connection through the integrated design
2Reliability
If multiple pins are used to secure the bracket and lifting/lowering device, then the reliability of mounting is improved, but the installation time and productivity are reduced
Solution Approach 1:
The support member pin integrates multiple fastening functions into a single component that simultaneously secures the bracket to the support member and provides the attachment point for the lifting/lowering device, reducing the number of installation steps and improving setup speed
Solution Approach 2:
The bracket is designed with a cut-out feature that is pre-configured to receive and retain the support member pin, allowing for quick alignment and insertion without requiring complex alignment procedures or multiple fastening operations
3Reliability
If additional pins are used for attachment, then the safety compliance is improved, but the cost of the mounting apparatus increases
Solution Approach 1:
The patent reduces the total number of components by combining the attachment pin function with the support member pin, eliminating the need for additional pins while maintaining safety compliance through the integrated design that provides equivalent or superior securement
4Ease of operation
If a single pin is used to attach the bracket and lifting/lowering device, then the ease of operation and installation are improved, but the perceived security and reliability may be reduced
Solution Approach 1:
The support member pin is designed with a head portion that provides a large bearing surface against the bracket and a shaft portion that extends through the support member, creating a robust single-point attachment that combines ease of installation with high security through its integrated load-bearing design
Solution Approach 2:
The pin head is designed with a curved or rounded shape that distributes load across a broader area of the bracket, enhancing the mechanical strength and security of the single-pin attachment while maintaining ease of insertion and removal
