Elastic Carrying Strap With Limitation Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying systems, such as backpacks, fail to adequately address the increased dynamic load and torque experienced during movement, particularly when the object's center of mass moves away from the wearer's center of mass, leading to discomfort and instability.
Innovation Solution
A carrying system featuring an essentially elastic portion attached to a backpack or bag at a first position and a limitation arrangement at a second position, which includes a limitation strap and guiding portion, allowing the elastic portion to extend and then be stabilized, thereby reducing torque and improving comfort by pulling the object closer to the body and distributing the load more ergonomically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic portion is used in the carrying strap to absorb dynamic load, then comfort during movement is improved, but the strap extends too far causing the object to move away from the body increasing torque
Solution Approach 1:
The carrying strap incorporates an elastic portion that dynamically adapts to movement conditions, allowing extension during impact absorption while maintaining control through the limitation arrangement
Solution Approach 2:
The limitation arrangement changes the effective length parameter of the carrying strap by providing a retraction path, allowing the strap to extend to a controlled maximum length and then retract, optimizing both comfort and torque reduction
2Adaptability or versatility
If the carrying strap is made longer to allow movement, then range of motion is improved, but stability deteriorates as the object moves further from the body
Solution Approach 1:
The limitation arrangement provides a dynamic length adjustment mechanism that allows the strap to extend during movement and retract during stability phases, optimizing both range of motion and stability
Solution Approach 2:
The limitation arrangement acts as an intermediary mechanism between the elastic portion and the backpack, controlling the maximum extension and providing a retraction path to maintain optimal positioning
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 effectively dampens vertical and horizontal movements, reducing the perceived weight and torque, enhancing wearing comfort and stability by adjusting to the wearer's anatomy and movement dynamics.
