Energy Storage Unit Adhesive Structure for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatuses with multiple energy storage devices arranged side by side lack sufficient vibration and impact resistance due to inadequate adhesive strength between devices, primarily because the adhesive thickness is reduced for miniaturization, leading to insufficient bonding.
Innovation Solution
The energy storage apparatus incorporates a concave surface on one energy storage device with an adhesive body within this concave area and a spacer positioned differently, which maintains the adhesive thickness and prevents compression, enhancing the bonding strength between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the adhesive thickness is reduced to miniaturize the energy storage apparatus, then the distance between energy storage devices is reduced, but the adhesive strength becomes insufficient
Solution Approach 1:
The adhesive structure is segmented into two functional parts: a thin adhesive layer for miniaturization and a foam adhesive body for strength. This segmentation allows each part to fulfill its specific function - the thin layer reduces overall size while the foam body provides bonding strength and vibration resistance.
Solution Approach 2:
The invention uses a composite adhesive structure combining a first adhesive (thin layer) and a foam adhesive body (cushioning layer). This composite approach integrates the advantages of both materials - the first adhesive provides initial bonding while the foam adhesive body maintains thickness and provides mechanical strength and vibration resistance.
2Volume of moving object
If the adhesive thickness is reduced to improve miniaturization, then the apparatus size is reduced, but the vibration resistance and impact resistance deteriorate
Solution Approach 1:
The foam adhesive body is placed beforehand between the energy storage devices to provide cushioning and maintain adhesive thickness. This pre-positioned cushioning layer prevents direct contact and potential damage during vibration and impact, while also maintaining the required bonding strength.
Solution Approach 2:
The composite adhesive structure combines a thin first adhesive layer with a foam adhesive body. The foam material provides elastic cushioning properties that absorb vibration and impact energy, while the thin first adhesive layer enables miniaturization. This composite approach simultaneously achieves size reduction and improved reliability.

AI summary
An energy storage apparatus includes an energy storage unit including a first energy storage device and a second energy storage device that are arranged in a first direction. The first energy storage device includes a concave part in which a surface of the first energy device, the surface opposite to the second energy storage device is recessed. The energy storage unit further includes: a first adhesive body that is disposed in the concave part between the first energy storage device and the second energy storage device and adheres to the first energy storage device and the second energy storage device; and a spacer that is disposed between the first energy storage device and the second energy storage device at a position different from the first adhesive body in a second direction intersecting with the first direction.
