Solution Overview

Problem

The existing battery mounting arrangement in work vehicles, such as tractors, is complex and requires simplification for easier maintenance and installation.

Innovation Solution

A battery mounting system where the battery is mounted on a bottom member with a separable design, featuring a mounting member and a separate member that can be easily detached without interfering with the leg portions of the steering-wheel post, allowing for simplified installation and maintenance by using a connector device for separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery is mounted on a frame structure inside the front control tower, then the battery can be securely accommodated, but the mounting arrangement becomes complicated

Engineering Contradiction:

Improvebattery accommodation stabilityVSAvoidmounting arrangement complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bottom member is divided into a mounting member and a separate member that can be detached from each other. The mounting member remains fixed to the frame structure providing stable battery mounting, while the separate member can be removed independently for maintenance operations without disturbing the battery installation.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the bottom member is made as a single integrated structure, then the battery mounting is stable, but maintenance operations require detaching the battery from the bottom member

Engineering Contradiction:

Improvemounting stabilityVSAvoidmaintenance accessibility

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The bottom member is segmented into a mounting member that provides stable battery mounting and a separate member that can be detached for maintenance. This segmentation allows the separate member to be removed independently, providing access to components behind it without requiring battery detachment.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the separate member is detached for maintenance, then accessibility is improved, but the leg portions may interfere with separation

Engineering Contradiction:

Improveseparation easeVSAvoidinterference from leg portions

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The separate member is designed to be extractable from the mounting member at a specific separation location. The steering-wheel post is positioned such that its leg portions do not interfere with the separation path, allowing the separate member to be cleanly detached without obstruction from other components.

Inventive Principle:

Principle #2Taking out (Extraction)
