Solution Overview

Problem

The challenge is to prevent the risk of damage from acid electrolyte or gases emitted during battery replacement in vehicles, particularly when dealing with batteries that have two vent holes, where one hole is left open, leading to potential leakage into hazardous areas.

Innovation Solution

A support kit for vehicle battery caps, comprising multiple detachable caps and a securing member, allows for easy replacement and adaptation to different battery configurations, with features like breakable connections, varying sizes, and a frame design that includes a stiffening block and elastically deformable clamps for secure fixing, ensuring all caps are kept in one place and easily accessible.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple separate battery caps are stored in the vehicle, then each cap can be individually accessed, but the risk of losing caps increases and mounting becomes more complex

Engineering Contradiction:
ImproveIndividual cap accessibilityVSAvoidCap retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

Multiple individual battery caps are merged into a single integrated support structure. The support holds several caps together as one unit, preventing loss while allowing individual caps to be detached and installed on different degassing holes. This resolves the contradiction by combining storage reliability with operational accessibility.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If a battery with two vent holes is installed without proper sealing, then the battery can function normally, but acid electrolyte or gases can leak into hazardous areas causing damage

Engineering Contradiction:
ImproveBattery installation speedVSAvoidAcid electrolyte leakage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The support structure preliminarily prepares multiple caps in the correct positions before battery installation. The caps are pre-arranged on the support, allowing the user to quickly select and install the appropriate cap on the second degassing hole immediately after battery mounting, preventing acid electrolyte or gas leakage before it can cause damage.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If caps are made in different sizes and shapes, then they can adapt to various battery configurations, but manufacturing complexity increases

Engineering Contradiction:
ImproveBattery configuration compatibilityVSAvoidCap production complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The support structure implements local quality by providing different cap types (different sizes and shapes) at specific locations on the support. Each cap position is designed with the appropriate cap type for specific battery configurations, allowing versatility in adapting to different batteries while maintaining standardized manufacturing processes for the support structure itself.

Inventive Principle:
Principle #3Local quality
