Solution Overview

Problem

Existing battery holding structures for vehicles require separate processes to remove the battery band and disconnect battery wire terminals, complicating the installation and removal of batteries.

Innovation Solution

A battery holding structure with a battery tray, a ground wire connected to a grounding member, and a wire clamp to prevent the battery tray from being pulled out, allowing for simultaneous disconnection of the ground wire and exposure of the positive terminal for maintenance, eliminating the need for a battery band and simplifying the maintenance process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a battery band is used to prevent battery movement, then the battery is secured in position, but the battery band must be removed separately from the ground wire during maintenance

Engineering Contradiction:
Improvebattery position stabilityVSAvoidmaintenance procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the movement prevention function and the electrical connection function into a single integrated component. The ground wire serves dual purposes: it provides electrical grounding and acts as the movement prevention mechanism through its routing and tension, eliminating the need for a separate battery band and simplifying maintenance to a single disconnection step.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The ground wire is designed to perform multiple functions simultaneously: electrical grounding, battery tray movement prevention, and maintenance access control. This multi-functional design reduces the number of separate components needed and streamlines the maintenance process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If the grounding member fastening member is disposed more outwardly than the movement prevention member, then the ground wire can be easily accessed, but the battery tray can be pulled out unintentionally

Engineering Contradiction:
Improveground wire accessVSAvoidbattery tray position stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent resolves the spatial conflict by arranging components along the widthwise direction of the vehicle. The movement prevention member is positioned more outwardly than the fastening member in the widthwise dimension, creating a layered configuration that prevents battery tray removal while maintaining ground wire accessibility through the widthwise spacing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The movement prevention member is positioned to engage the ground wire before the fastening member can be accessed. This preliminary positioning of the ground wire by the movement prevention member ensures that the battery tray cannot be pulled out unintentionally, while still allowing controlled access during maintenance procedures.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the ground wire is made long to allow movement, then the battery tray can be pulled out for maintenance, but the battery tray cannot be prevented from being pulled out

Engineering Contradiction:
Improvebattery tray accessibilityVSAvoidbattery tray position stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The ground wire is designed with appropriate length and routing to provide controlled flexibility. It allows the battery tray to be pulled out to a limited extent for maintenance access while the movement prevention member maintains tension to prevent complete removal or unintentional displacement, creating a dynamic balance between accessibility and stability.

Inventive Principle:
Principle #15Dynamics

AI summary

A battery holding structure includes a battery tray 61 for storing a battery 32 therein, a battery holding rack 41, for storing the battery tray 61 with the battery 32 stored therein and allowing the battery tray 61 to be pulled out along widthwise directions of the vehicle, a ground wire 38 having one end connected to a negative terminal 32m of the battery 32 and another end connected to a grounding member 20 on a vehicle frame, and a movement prevention member (wire clamp 65) for fixing the other end of the ground wire 38 to the battery tray 61 and preventing the battery tray 61 from being pulled out to one side along the widthwise directions of the vehicle with the ground wire 38 which is connected to the grounding member 20. The structure facilitates the installation and removal of a battery while preventing the battery from moving in a battery holding structure for a vehicle.
