Rotating Lock Strap Assembly for High-Voltage Protective Sleeves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing protective sleeves in high-voltage environments lack adequate safety features and ease of use, posing risks for individuals working with high-voltage electricity.
Innovation Solution
A strap assembly with a connector system, including a strap and adjustment clip, designed to securely attach protective sleeves, featuring a locking mechanism that ensures the strap remains in place even under extreme conditions, using materials like flame-retardant polymers and high-strength textiles for durability and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to secure protective sleeves, then the protective sleeves can be attached to the person, but the safety and ease of use are inadequate
Solution Approach 1:
The fastening system is divided into separate components: a strap with connectors for attaching to protective sleeves, and a distinct adjustment clip for securing the strap. This segmentation allows each component to be optimized for its specific function while working together to provide both safety and ease of use.
Solution Approach 2:
The adjustment clip incorporates a rotatable locking member that can transition between locked and unlocked positions, enabling dynamic adjustment of the strap length. This mechanical dynamic system allows users to easily adjust the fit while maintaining secure attachment when locked, addressing both safety and ease of operation requirements.
2Reliability
If the strap assembly is made secure and adjustable, then safety is improved, but the device complexity increases
Solution Approach 1:
The locking member is designed to automatically lock when the strap is tightened or adjusted, eliminating the need for additional locking actions. The mechanism self-secures the strap in place through its own structural design, reducing operational steps while maintaining secure attachment and minimizing perceived complexity.
Solution Approach 2:
The locking function is extracted as a separate, dedicated component (the rotatable locking member) rather than being integrated into the entire strap assembly. This extraction allows the locking mechanism to be optimized independently while keeping the overall device structure relatively simple and manageable.
3Reliability
If the locking mechanism is added to prevent strap sliding, then reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The locking member operates through periodic rotation between distinct positions (locked and unlocked). This periodic action provides clear, discrete states that are easy to understand and operate, ensuring reliable locking when needed while maintaining simplicity in the adjustment process.
Solution Approach 2:
The rotatable locking member acts as an intermediary mechanism between the strap and the adjustment clip. It translates simple rotational input into secure locking action, providing reliable prevention of strap sliding while maintaining ease of operation through a simple rotating motion that can be easily performed with one hand.

AI summary
A strap assembly includes first second connectors that attach to protective sleeves, a strap with one end at the first connector and passing through a slot at the second connector, a strap adjustment clip with a base member connected to the second end of the strap and an upper surface, a locking member rotatably attached to the base member with the strap in between. The locking member is rotatable between a locked position and an open position and has a lever extension having and a strap lock extension including a strap lock distal end that traps the strap body against the upper surface of the base member when the locking member is in the locked position.
