Energy Storage Apparatus Positioning Projection Assembling Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatus configurations exhibit poor assembling operability due to their structural complexities, making it difficult to insert and position energy storage devices efficiently.
Innovation Solution
An energy storage apparatus with an outer case featuring positioning projections on its inner surfaces, extending orthogonally towards the lower side, allowing adjacent devices to be positioned without obstructing insertion, and optionally using an aligning projection for further stability and alignment.

Engineering Contradiction Analysis
1Ease of operation
If conventional positioning structures (leaf springs, partition walls, circular columnar bodies) are used to position energy storage devices, then positioning function is achieved, but assembling operability deteriorates due to structural complexity
Solution Approach 1:
The positioning function is segmented into multiple simple positioning projections distributed on the inner surfaces of the outer case, rather than using a single complex positioning structure. Each projection independently provides positioning for adjacent energy storage devices, simplifying the overall structure while maintaining effective positioning capability
Solution Approach 2:
The positioning function is extracted from complex mechanical structures (leaf springs, partition walls) and implemented through simple geometric features (projections) directly formed on the outer case, eliminating the need for separate positioning components and reducing structural complexity
2Manufacturing precision
If positioning structures extend towards the opening portion, then positioning precision is improved, but insertion difficulty increases due to obstruction
Solution Approach 1:
The positioning projections extend in the second direction (orthogonal to the arrangement direction) rather than extending toward the opening portion in the first direction. This dimensional change allows the projections to provide precise positioning without obstructing the insertion path of energy storage devices at the opening portion
Solution Approach 2:
The positioning projections are asymmetrically positioned and oriented relative to the opening portion, extending perpendicular to the insertion direction. This asymmetric configuration enables the projections to contact and position the side surfaces of energy storage devices during insertion without creating obstruction at the opening

AI summary
An energy storage apparatus including: an outer case having an opening portion; a plurality of energy storage devices arranged in a first direction in the outer case; and a positioning projection disposed on opposedly facing inner side surfaces of the outer case, extending in a second direction substantially orthogonal to the first direction toward a lower side of the outer case opposite from the opening, and being capable of positioning the adjacently disposed energy storage devices at the lower side of the outer case.
