Battery Unit Movement Assist Tool for Inclined Self-Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually moving or placing a heavy battery unit is burdensome due to its weight, and existing solutions do not provide a simple configuration for maintaining a self-supporting and movable state, especially when the battery unit is inclined with wheels touching the ground and ground contact portions raised.
Innovation Solution
A movement assisting tool with an attachment portion, leg portions, and moving wheels that can be attached to the battery unit, allowing it to maintain an inclined orientation with the wheels touching the ground and ground contact portions raised, enabling stable self-support and movement without needing to support the entire weight of the battery unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery unit is manually moved by grabbing the operation handle and maintaining an inclined state, then the battery unit can be moved with wheels touching the ground, but the operator bears a heavy burden due to the weight of the battery unit
Solution Approach 1:
The movement assisting tool serves as an intermediary device between the operator and the battery unit. By attaching the tool to the battery unit and using its moving wheels to contact the ground, the operator can move the battery unit without directly bearing its full weight, thus reducing operational burden while maintaining ease of movement
2Reliability
If a movement assisting tool is designed to support the entirety of the battery unit, then the battery unit can be moved in a self-supported state, but the tool becomes overly large and complex
Solution Approach 1:
The movement assisting tool is designed with a segmented structure consisting of an attachment portion, leg portions, and moving wheels. This segmentation allows the tool to support only the necessary portion of the battery unit's weight while maintaining a compact and simple structure, avoiding the need to support the entire battery unit
Solution Approach 2:
The battery unit's own wheels are utilized in cooperation with the moving wheels of the tool to achieve self-supporting movement. This self-service approach allows the system to maintain reliability without requiring the tool to be overly large or complex, as the battery unit's existing structure contributes to the support function
3Productivity
If the battery unit is moved with ground contact portions raised above the ground, then the battery unit can be in a movable state, but the stability is reduced compared to a flat position
Solution Approach 1:
The leg portions of the movement assisting tool act as intermediaries that bridge the attachment portion and the moving wheels. This structure enables the battery unit to maintain a stable inclined state with ground contact portions raised, facilitating efficient movement while preserving adequate stability through the mediating support structure

AI summary
A movement assisting tool (23) includes an attachment portion (24) that can be attached to and removed from a main body portion (11) of a battery unit (4), leg portions (25) that are coupled to the attachment portion (24) and extend from the attachment portion (24), and moving wheels (26) that are supported by extension portions of the leg portions (25). In a state where the attachment portion (24) has been attached to the main body portion (11) of the battery unit (4) and the moving wheels (26) are touching the ground, the battery unit (4) can be kept in an inclined orientation in which the wheels (13) are touching the ground and ground contact portions (14) are raised above the ground.
