Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As battery capacity increases, so does its weight, necessitating a stronger battery housing tray without significantly increasing material usage.
Innovation Solution
A battery housing tray design featuring spaced housing parts with annular insertion openings and integrated by joining parts, forming a grid structure that reduces material usage while enhancing strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the strength of the battery housing tray is enhanced to support heavier batteries, then the load-bearing capacity improves, but the amount of material used increases
Solution Approach 1:
The housing parts are divided into multiple insertion-side annular parts that are spaced apart from each other, forming a segmented structure. This segmentation allows the tray to maintain strength while using less material compared to a solid continuous structure
Solution Approach 2:
Multiple insertion-side annular parts are joined and integrated by insertion-side joining parts to form an integrated grid structure. This merging of separate components creates a unified structure that provides enhanced strength and rigidity while maintaining material efficiency
2Strength
If the housing parts are joined to form an integrated structure, then the strength and rigidity improve, but the manufacturing complexity increases
Solution Approach 1:
The joining parts are designed to integrate multiple annular parts into a unified structure, creating enhanced strength and rigidity through the combined configuration of separate components

AI summary
The purpose of the present disclosure is to provide a battery accommodation tray in which the amount of material used is readily reduced and of which the strength is readily improved. The battery accommodation tray comprises a plurality of accommodation parts that respectively accommodate batteries and that are positioned at intervals from each other. The accommodation parts have insertion openings demarcated by insertion-side circular parts that have a circular shape when viewed from the insertion side of the batteries in the height direction (Z direction). The battery accommodation tray has insertion-side connection parts by which the outer peripheral surfaces of the insertion-side circular parts are connected to the outer peripheral surfaces of adjacent insertion-side circular parts. The plurality of insertion-side circular parts are connected by the plurality of insertion-side connection parts to form an integrated whole.
