Integrated Strap Fastening Unit for Adjustable Length and Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strap assemblies with adjustable lengths are cumbersome, uncomfortable, and prone to accidents due to separate adjusting rings and fasteners, which increase weight, complicate assembly, and expose surplus strap material, risking neck constriction and external damage.
Innovation Solution
A fastening unit with a base, fixing seat, shaft seats, main body, engaging member, and abutting member, featuring an elastic compression portion and flexible segment, allows for adjustable strap length and safe use by engaging and disengaging to pivot relative to shaft seats, preventing external forces from causing injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate adjusting ring and fasteners are used, then the strap assembly can be adjusted and secured, but the weight increases and assembly becomes complicated
Solution Approach 1:
The patent combines the adjusting ring and fastener into a single integrated fastening unit. The fastening unit includes a body with a through hole for the strap, an engaging member with elastic compression portion that can engage with the fixing seat, and an abutting member that abuts against the strap. This integration eliminates the need for separate adjusting ring and fastener components, simplifying assembly while maintaining adjustability and securing functions.
2Adaptability or versatility

This integration eliminates the need for separate adjusting ring and fastener components, simplifying assembly while maintaining adjustability and securing functions.
3Length of moving object
If adjusting ring is used to adjust strap length, then the strap can be lengthened, but the surplus portion is exposed and may cause accidents
Solution Approach 1:
The patent combines the adjusting ring and fastener into a single integrated fastening unit. The fastening unit includes a body with a through hole for the strap, an engaging member with elastic compression portion that can engage with the fixing seat, and an abutting member that abuts against the strap. This integration eliminates the need for separate adjusting ring and fastener components, simplifying assembly while maintaining adjustability and securing functions.
4Length of moving object
If adjusting ring is used to adjust strap length, then the strap can be lengthened, but the user feels uncomfortable due to neck constriction
Solution Approach 1:
The patent combines the adjusting ring and fastener into a single integrated fastening unit. The fastening unit includes a body with a through hole for the strap, an engaging member with elastic compression portion that can engage with the fixing seat, and an abutting member that abuts against the strap.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies assembly, reduces weight and cost, enhances user comfort, and prevents accidents by allowing secure strap adjustment and detachment, ensuring safety and ease of use.
Implementation Method 1
the elastic compression portion is deformed so as to facilitate the disengagement of the elastic compression portion from the fixing seat
Implementation Method 2
The flexible segment connects the extending segment to the engaging portion and is configured to provide flexibility to the engaging portion in the first direction
Implementation Method 3
the two shafts leave the shaft holes via the guiding grooves

AI summary
A fastening unit includes a base, a fixing seat, two shaft seats, a main body, an engaging member, and an abutting member. The fixing seat and the two shaft seats are disposed on the base. The main body is detachably disposed on the two shaft seats. The engaging member is connected to the side of the main body that is away from the two shaft seats. The abutting member protrudes from the bottom surface of the main body. When the fastening unit is in a closed state, the engaging member engages with the fixing seat. As a result, the bottom surface faces the base, and the abutting member is adjacent to the base. When the fastening unit is transferred from the closed state to an opened state, the engaging member disengages from the fixing seat, and the main body pivots relative to the two shaft seats.
