Portable Energy Storage Carrying Strap for Reduced Arm Fatigue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power supplies are labor-intensive to carry due to the need for arm strength, leading to discomfort and inconvenience, especially for prolonged outdoor use.
Innovation Solution
An energy storage power supply with a handle and detachable strap system, allowing users to carry the device securely over the shoulder, distributing the weight and reducing muscle strain through adjustable buckles and a foldable lampshade for improved stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the energy storage power supply is carried using only a handle, then the structure is simple, but the user experiences arm muscle ache and fatigue during prolonged use
Solution Approach 1:
The carrying function is segmented between two independent components: a handle for hand carrying and a strap for shoulder carrying. This allows the user to switch between carrying methods based on duration needs, resolving the contradiction between simplicity and prolonged usability.
Solution Approach 2:
The carrying method transitions from one-dimensional (handle-only, hand-based) to two-dimensional (handle plus strap, enabling shoulder-based carrying). This dimensional expansion allows weight distribution across the shoulder rather than concentrated arm muscles, enabling prolonged carrying without fatigue.
2Ease of operation
If a strap is added to enable shoulder carrying, then the carrying comfort is improved, but the device complexity increases
Solution Approach 1:
The strap is detachably connected to the handle through hanging parts, merging the strap and handle into a coordinated carrying system. This integration allows the strap to function effectively while maintaining the simplicity of the original handle structure, balancing comfort improvement with structural simplicity.
Solution Approach 2:
The strap is designed as detachable rather than permanent, allowing dynamic configuration. Users can attach or detach the strap based on carrying needs, enabling the device to adapt between simple (handle-only) and enhanced (strap-plus-handle) modes, thus managing complexity flexibly.
3Adaptability or versatility
If the strap is detachably connected to the handle, then the versatility is improved, but the connection reliability may be compromised
Solution Approach 1:
Hanging parts are pre-installed on the handle during manufacturing, ready for strap attachment. This preliminary preparation ensures that when the strap is attached, the connection is immediately reliable without requiring additional assembly steps or complex fastening mechanisms, thus maintaining both versatility and reliability.
