Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved methods and arrangements to securely mount and detach fall arrest devices on structures like towers, derricks, and drilling rigs, while allowing for easy replacement and maintenance, especially during transportation.
Innovation Solution
A mounting bracket with a base element and a front retainer element, featuring spacer struts and a resilient engagement mechanism, which securely attaches the fall arrest device to a structure and allows for easy attachment and detachment, while maintaining the device in place during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fall arrest device is securely mounted to a structure using a rigid bracket, then the reliability of the mounting is improved, but the ease of operation for attachment and detachment deteriorates
Solution Approach 1:
The mounting bracket is divided into a base element and a front retainer element that can move relative to each other along a movement path. This segmentation allows the front retainer element to be positioned in different locations (first location for secure retention, second location for easy detachment) while maintaining overall mounting reliability through the resilient engagement mechanism.
Solution Approach 2:
The front retainer element is designed to be movable rather than fixed, allowing it to transition between a first position that securely retains the fall arrest device and a second position that facilitates easy detachment. This dynamic capability enables the bracket to adapt between secure mounting and easy operation modes.
2Reliability
If the fall arrest device is firmly secured to prevent movement during use, then the safety is improved, but the ability to replace and repair the device deteriorates
Solution Approach 1:
The front retainer element's movability along the movement path enables it to switch between a secure retention position that ensures safety during use and a detachment position that facilitates easy device replacement and repair, resolving the contradiction between firm securing and replaceability.
Solution Approach 2:
The resilient engagement element acts as an intermediary mechanism that provides secure engagement when the front retainer element is in the first position, ensuring safety, while allowing controlled disengagement when moved to the second position, enabling easy device replacement without compromising either safety or repairability.
3Ease of operation
If a resilient engagement element is added to improve ease of attachment, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The bracket is segmented into distinct functional elements (base element, front retainer element, resilient engagement element) where each component has a specific role. This modular segmentation allows the resilient engagement element to be integrated in a way that improves attachment ease while keeping the overall structure organized and manageable, minimizing unnecessary complexity.
