Sliding Handle Assembly for Energy Storage Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatuses face poor assembling operability due to the grip not being attachable to the container before energy storage devices are inserted, and difficulty in carrying due to insufficient space between the grip and lid, especially when the apparatus is unbalanced in weight.
Innovation Solution
An energy storage apparatus design where a handle is mounted on the lid body with slide portions on the handle and corresponding slide receiving portions on the lid, allowing the handle to be assembled and slid smoothly, ensuring improved assembling operability and stable carrying by aligning the lifting and sliding directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the grip is attached to the container side surface, then the container structure is simplified, but the assembling operability deteriorates because the grip cannot be assembled in advance before energy storage devices are inserted
Solution Approach 1:
The handle is assembled to the lid body in advance before the energy storage devices are inserted into the container. The lid body with the pre-assembled handle is then attached to the container body, allowing the handle to be positioned and secured before the final assembly step. This preliminary action improves assembling operability while maintaining container structure simplicity.
2Ease of operation
If the grip is configured to be pulled out in a curved shape, then the grip can be mounted on the lid, but the space between the grip and lid becomes insufficient, making it difficult to carry the energy storage apparatus
Solution Approach 1:
The handle is configured to slide in a straight line along the sliding direction that coincides with the lifting direction, rather than moving in a curved path. The slide portions on the handle body engage with slide receiving portions formed on the lid body, enabling linear motion. This dimensional change from curved to linear movement increases the space between the handle and lid, improving carryability while maintaining ease of mounting.
3Ease of operation
If the sliding direction of the grip and lifting direction are orthogonal, then the grip can be mounted on the lid, but the configuration is not suitable for carrying unbalanced energy storage apparatus
Solution Approach 1:
The handle and lid body are configured with asymmetric sliding and lifting directions that coincide with each other, rather than being orthogonal. The slide portions and slide receiving portions are positioned and oriented to enable linear motion along the same axis. This asymmetric configuration aligns the handle's movement with the lifting direction, providing stable support for carrying unbalanced energy storage apparatus while maintaining ease of mounting.

AI summary
An energy storage apparatus includes: an outer case formed of a body, and a lid body which covers an opening of the body; an energy storage device which is accommodated in the outer case; and a handle which is mounted on the lid body. The lid body has a first surface, and a second surface which is disposed adjacently to the first surface. The handle is formed of a handle body extending from one end side toward the other end side, and slide portions which are respectively formed on both end sides of the handle body. The handle body is disposed on the first surface. Slide receiving portions which hold the slide portions in a slidable manner are formed on the second surface.
