Hookless Strap Loop Fastening for Secure Damage-Free Bundling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strap designs with hooks pose risks of damage and safety hazards due to their rigid nature, and existing multipurpose straps lack versatility and adaptability in various applications.
Innovation Solution
A multipurpose strap system utilizing a silicone-reinforced fiberglass composition with dynamic hook-and-loop fasteners on opposing sides of the main band, allowing for adjustable loops and eliminating the need for traditional hooks, enabling secure and versatile fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hooks are used for fastening, then secure attachment is achieved, but damage and safety hazards occur
Solution Approach 1:
The patent removes the harmful hook component from the strap system entirely, replacing it with a hookless design that uses a different fastening mechanism (cam buckle or other non-hook fasteners) to achieve secure attachment without the damage and injury risks associated with traditional hooks
Solution Approach 2:
The patent introduces an intermediary fastening mechanism (cam buckle or alternative fastener) that mediates between the need for secure attachment and the need to avoid damage, providing a reliable connection method that does not rely on hooks and therefore does not cause the harmful effects associated with hook-based fastening
2Device complexity
If single-purpose straps are used, then simple design is maintained, but versatility and adaptability are limited
Solution Approach 1:
The patent creates a universal strap system that can be used for multiple purposes including securing cargo, bundling items, and various other applications through the combination of adjustable length, different fastening options, and the ability to configure straps in different arrangements, all while maintaining relatively simple individual component designs
Solution Approach 2:
The patent divides the strap into separate functional components (strap body, fasteners, buckles) that can be independently selected and combined, allowing the system to be adapted to different applications while keeping each individual component simple and manageable
3Ease of operation
If elastic materials like nylon or polyester are used, then flexibility is achieved, but hook-related damage risks remain
Solution Approach 1:
The patent removes the harmful hooks from elastic strap designs while maintaining the flexibility and elasticity benefits of materials like nylon or polyester, achieving a configuration that provides both operational flexibility and safety by eliminating the damage-causing hook component

AI summary
A multipurpose strap system is provided. The multipurpose strap system includes an elongated main strap with first and second fasteners affixed at respective ends. The first and second fasteners form closed loops on the first side of the elongated main strap, allowing versatile applications for coupling items, securing to itself, or other similar straps. The system further includes an extension attachment, providing adaptability. The strap system lacks hooks to improve safety and ease of use. The fasteners include two components, with one fastener component being permanently secured to the main strap on one side and the other fastener component being secured on the other side, such that it extends past a distal end of the main strap. The closure of the fastener components allows for the formation of a closed loop that secures items or other straps to the multipurpose strap system.
