Backpack Carrying Device with Articulated Lap Belt and Battery Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack devices lack an efficient articulated connection of the lap belt unit to the support base and adequate adjustability of the shoulder strap unit, as well as optimal attachment mechanisms for carrying battery packs, particularly for electrical gardening and forestry equipment.
Innovation Solution
The backpack device features a double joint articulation system allowing the lap belt unit to pivot about two axes, and a detachable shoulder strap unit with adjustable rigid strap holders and flexible straps, along with a holding device for the battery pack that includes a docking mechanism and retaining system for secure attachment and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the lap belt unit is rigidly connected to the support base, then structural stability is improved, but adaptability and comfort are worsened
Solution Approach 1:
The patent applies the dynamics principle by implementing a double joint connection that allows the lap belt unit to pivot relative to the support base about two different axes. This creates a dynamic connection that adapts to different carrying positions and user movements, resolving the contradiction between structural stability and adaptability by providing both firm attachment and movement freedom.
2Adaptability or versatility
If the shoulder strap unit is made adjustable with multiple components, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The patent applies segmentation by dividing the shoulder strap unit into separate adjustable components including strap length adjustment mechanisms and position adjustment features. This allows independent adjustment of different strap parameters without requiring complete redesign, achieving high adaptability while managing complexity through modular design.
3Ease of operation
If the battery pack attachment mechanism is simplified, then ease of operation is improved, but reliability is worsened
Solution Approach 1:
The patent merges multiple attachment functions into an integrated holding device that combines a docking device for pivotal attachment with a locking device for secure positioning. This unified mechanism achieves both easy operation through a single docking action and reliable attachment through automated locking, resolving the contradiction between simplicity and security.
