Adjustable Carrying Device Strap Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adjustable carrying devices are unable to accommodate articles of varying sizes in both girth and length securely, often being cumbersome to adjust and featuring straps that create 'catch points' inhibiting insertion or removal of items.
Innovation Solution
An adjustable carrying device with a main body, receptacle, and top strap that passes over the peripheral edge, utilizing hook and loop fasteners for easy adjustment and secure retention, allowing for variable internal volume and strap positioning to accommodate different article sizes without intruding into the receptacle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straps are disposed within the receptacle to retain articles, then article retention is improved, but insertion and removal are hindered due to catch points
Solution Approach 1:
The strap is extracted from the interior of the receptacle and repositioned to pass over the peripheral edge. This removes the source of catch points while preserving the retention function through external positioning and engagement with the rear surface.
2Adaptability or versatility
If adjustable carrying devices use straps fed through slots and openings for size adjustment, then adaptability is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The adjustment mechanism is segmented into discrete repositionable attachment points along the strap and corresponding engagement points on the rear surface. This allows incremental adjustment while simplifying the overall mechanism compared to continuous adjustment systems.
Solution Approach 2:
The strap configuration is made dynamic and reconfigurable, allowing the user to adjust the strap position and length to accommodate different article sizes. The removably coupled ends enable flexible reconfiguration without permanent fixed positions.
3Reliability
If carrying devices are sized specifically for each article, then article fit and retention are improved, but adaptability deteriorates
Solution Approach 1:
The carrying device incorporates universal adjustment capabilities through the reconfigurable strap system with multiple engagement points. This single device can accommodate articles of various sizes by adjusting the strap configuration, eliminating the need for multiple specialized carrying devices.

AI summary
An adjustable sheath for carrying an article includes a main body having a front surface, a rear surface opposite the front surface, and a peripheral edge, a receptacle configured to receive an article, wherein the receptacle is coupled to the front surface and the receptacle includes an outer surface, and a strap configured to retain the article within the receptacle, the strap including a first end portion removably coupled to the rear surface of the main body and a second end portion removably coupled to the outer surface of the receptacle. The top strap passes over the peripheral edge of the main body when coupled to the rear surface main body and the outer surface of the receptacle.
