Resilient Strap Mounting for Athletic Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional athletic packs can be restrictive and limit movement due to their rigid structures, which do not adequately account for the flexibility and motion required during certain activities, leading to discomfort and hindrance in user mobility.
Innovation Solution
A resilient strap mounting system featuring a flexible body member with angled arms and a base, constructed from thermal plastic elastic (TPE) or similar materials, allowing for three-way stretching through strategically placed slot holes and supporting ridges, enabling improved shoulder and arm movement without displacing the pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame structure is used in athletic packs, then structural stability and load support are improved, but user flexibility and movement freedom deteriorate
Solution Approach 1:
The patent replaces rigid frame structures with flexible strap mountings made of elastic materials that can bend and stretch, allowing the pack to adapt to user movement while maintaining structural integrity through the elasticity of the strap material itself
Solution Approach 2:
The strap mounting system transitions from a static rigid structure to a dynamic flexible system that can change shape and position in response to user movement, allowing the straps to flex and return to their original configuration
2Device complexity
If shoulder straps are directly attached to the pack, then structural simplicity is improved, but user movement freedom deteriorates due to restriction
Solution Approach 1:
The patent introduces flexible elastic strap mountings that incorporate bending and stretching capabilities into the strap attachment system, allowing user movement while maintaining a relatively simple overall structure through the use of elastic material properties
3Adaptability or versatility
If flexible materials are used for strap mounting, then user movement freedom is improved, but structural strength and stability deteriorate
Solution Approach 1:
The patent utilizes the elastic properties of the strap mounting material, where the material can temporarily deform under stress during movement and then return to its original shape, providing both flexibility during use and structural recovery to maintain strength
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 system enhances user flexibility and mobility while wearing the pack by allowing the strap mounting to flex and return to its original shape, maintaining pack position and comfort during athletic activities.
Implementation Method 1
The resilient strap mounting allows the flexibility and improved motion of the user while wearing the athletic pack through a flexible body member
Data Source
AI summary
A resilient strap mount allowing for increased flexibility and movement of a user's shoulders and arms while wearing an athletic pack is presented. The resilient strap mount is constructed having a flexible body member consisting of two body member arms and a body member base. Shoulder harness straps, attaching to shoulder harnesses of the athletic pack, are each respectively threaded through one of the body member arms. An athletic pack strap, attaching to the base of the body of the athletic pack, is threaded through the body member base. In a preferred embodiment, each body member arm is constructed with a body member neck having a thinner width and thickness than the remainder of the flexible body member and each member neck has a pair of slot holes to allow for increased flexibility and stretching of the resilient strap mount.
