Solution Overview

Problem

Electronic devices with mounted batteries face stress and potential damage due to external impacts, which can cause deformation, short circuits, heat generation, or ignition, exacerbated by gaps between the battery and mounting portions leading to repeated vibrations and stress.

Innovation Solution

A battery mounting structure with an elastic structure between the battery and the bracket, featuring an elastic member and adhesive members to absorb and disperse external impacts, maintaining a spacing distance and reducing movement between the battery and mounting space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the battery is disposed to be in contact with the inner face of the electronic device, then the structural support is improved, but external impact is directly transmitted to the battery causing stress and potential damage

Engineering Contradiction:

Improvestructural supportVSAvoidexternal impact transmission

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

An elastic structure is introduced as an intermediary component between the battery and the bracket. This elastic structure absorbs and disperses external impacts before they reach the battery, preventing direct transmission of harmful forces while maintaining structural support.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The elastic structure is pre-installed between the battery and the bracket to provide cushioning protection before any impact occurs. This preventive measure ensures that when external impacts occur, the battery is already protected by the elastic cushioning layer.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Adaptability or versatility

If a gap is generated between the battery and the mounting portion, then interference is minimized, but the battery moves under external impact causing repeated vibrations and stress

Engineering Contradiction:

Improveinterference minimizationVSAvoidbattery stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The elastic structure acts as a flexible element that fills the gap between the battery and the mounting portion. It provides just enough contact to prevent excessive movement and vibrations while maintaining the necessary clearance to minimize interference, achieving a balance between both requirements.

Inventive Principle:

Principle #30Flexible shells and thin films

3Stability of the object's composition

If the battery is tightly fixed to the mounting portion, then movement is reduced, but external impacts cause repeated vibrations and stress through impact with the mounting portion

Engineering Contradiction:

Improvebattery positioningVSAvoidrepeated vibrations and stress

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The elastic structure serves as a mediator between the battery and the rigid mounting portion. It allows the battery to be securely positioned while absorbing impact forces, preventing the transmission of repeated vibrations and stress that would occur with direct rigid contact.

Inventive Principle:

Principle #24Intermediary (Mediator)
