Crisscross Strap Tool Case for Secure Tethering Without Use Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety measures for preventing tools from falling during high-rise construction, such as debris nets and toe boards, have limitations, and there is a need for a solution that can securely tether tools without interfering with their use and accommodate tools of varying sizes and configurations, while minimizing swing and wear.
Innovation Solution
A case with crisscrossing straps and fasteners that securely enclose the tool's base portion and handle, allowing for easy use and adjustment, and attaching to a safety tether to prevent drops, using durable materials like canvas and woven nylon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tether is used to secure the tool, then tool drop prevention is improved, but interference with normal tool use increases
Solution Approach 1:
The securing device is divided into separate functional components: a case for storing smaller items, a tether for attachment, and a mounting mechanism. This segmentation allows the tool to be secured without the entire assembly interfering with tool operation, as only the minimal necessary components are in the tool's path.
Solution Approach 2:
The invention extracts the securing function from the tool itself by using a separate case and tether system. This allows the tool to remain unmodified and freely accessible, while the securing mechanism operates independently through magnetic attachment and strap fastening.
2Reliability
If a secure tethering system is designed, then tool retention is improved, but adaptability to various tool sizes and configurations decreases
Solution Approach 1:
The strap system incorporates adjustable length and positioning capabilities, allowing it to dynamically adapt to different tool sizes and configurations. The magnetic mounting system also allows flexible positioning on various tool surfaces regardless of size or shape.
Solution Approach 2:
The securing device is designed with universal compatibility features: the magnetic mounting can attach to various tool materials, the adjustable strap system accommodates different circumferences, and the case design fits multiple tool types. This multi-functionality enables one device to secure various tools without requiring tool-specific customization.
3Reliability
If fasteners are used to retain the tool, then tool security is improved, but wear and tear increases over time
Solution Approach 1:
The magnetic mounting system changes the retention mechanism from mechanical friction-based fastening to magnetic field-based holding. This parameter change eliminates wear on the tool surface while maintaining secure retention, as magnetic force does not degrade with repeated use like mechanical fasteners do.

AI summary
A case for a tool having a pocket with a base panel, first and second side panels, first and second end panels, and first and second slots. A first strap having a first proximal end affixed to the pocket first and a first distal end and a second strap having a second proximal end affixed to the pocket and a second distal end. The first and second straps are configured to crisscross each other, and the first distal end is configured to pass through the first slot and the second distal end is configured to pass through the second slot.
