Reinforced Storage Holder Structure for Insertion Load Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The bottom surface portion of storage devices, such as battery trays, is prone to deformation or damage when subjected to a predetermined load, necessitating enhanced durability against insertion loads.
Innovation Solution
A holding apparatus with a reinforcement portion made of a higher-strength material than the holding portion, combined with a support and shield structure, enhances the durability of the first portion by providing a layered structure and eliminating the need for fixing parts on the bottom portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bottom surface portion is made from a single material, then the structure is simple and easy to manufacture, but the durability against insertion loads is insufficient
Solution Approach 1:
The holding portion is constructed using composite materials: a resin base material provides the main structure, while a metal reinforcement portion (aluminum or stainless steel) is embedded in the bottom surface to enhance strength and durability against insertion loads. This composite structure resolves the contradiction by combining materials with complementary properties.
Solution Approach 2:
Instead of making the entire holding portion from high-strength material, the reinforcement portion is strategically placed only at the bottom surface where insertion loads are applied. This localized reinforcement approach enhances durability at the critical area while keeping the overall structure simple and cost-effective.
2Strength
If the reinforcement portion is made of metal material, then the strength is improved, but the electromagnetic wave transmission property deteriorates
Solution Approach 1:
A resin layer is introduced as an intermediary between the metal reinforcement portion and the external environment. This resin layer acts as an electromagnetic wave barrier, preventing harmful electromagnetic waves from passing through while allowing the metal reinforcement to provide structural strength. The resin mediates between the conflicting requirements of strength and electromagnetic shielding.
3Stability of the object's composition
If the reinforcement portion is fixed directly to the holding portion, then the structural integrity is improved, but contact noise is generated
Solution Approach 1:
The resin material serving as the base of the holding portion acts as a mediator between the reinforcement portion and the external environment. This resin layer provides structural bonding while simultaneously reducing contact noise by cushioning the connection between the metal reinforcement and the holding portion structure.

AI summary
A holding apparatus (1) includes a holding portion (2) including a first portion (31) and a second portion (32), the first portion holding a first surface of a storage device, the first surface facing a first direction, the second portion holding a second surface of the storage device, the second surface facing a second direction which intersects the first direction, the holding portion holding the storage device to be detachable. The holding apparatus (1) includes a reinforcement portion (400) at a surface (31b) of the first portion (31), the surface (31b) being located opposite to a surface that faces the storage device, the reinforcement portion (400) being constituted of a second material having higher strength and/or rigidity than a first material which constitutes the holding portion (2).
