Solution Overview

Problem

Existing methods for attaching wiring harnesses to vehicle batteries are impractical, requiring multiple people and tools, and do not allow for easy removal of batteries without disconnecting the harnesses, leading to inefficiencies and increased after-sales costs.

Innovation Solution

A cable channel with U-shaped clipping means that securely attaches to the battery, allowing it to be pre-fixed and removed without disconnecting the wiring harness, featuring foam positioning aids and reinforcing elements for precise alignment and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a separate fixing device is used to secure the battery to the vehicle floor, then the battery can be fixed, but the number of parts increases and assembly complexity increases

Engineering Contradiction:
Improvenumber of partsVSAvoidbattery fixing reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines the cable tray and battery fixing device into a single integrated component. The cable tray includes a battery receiving space with side walls that extend downward to form fixing surfaces, eliminating the need for separate fixing devices. The battery is secured through friction between the battery case and the fixing surfaces of the cable tray, reducing part count while maintaining fixing reliability.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If conventional cable trays are used without battery pre-fixing, then the cable tray structure is simple, but additional fixing devices and installation steps are required

Engineering Contradiction:
Improveinstallation convenienceVSAvoidcable tray structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable tray is designed with an integrated battery receiving space that includes side walls extending downward to form fixing surfaces. This merging of cable routing and battery fixing functions into a single component simplifies installation by eliminating separate fixing devices and steps, while the overall structural complexity remains manageable.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable tray serves multiple functions: it routes cables along the vehicle, provides a receiving space for the battery, and simultaneously acts as a fixing device through its downward-extending side walls. This multi-functionality improves installation convenience by consolidating multiple components into one, while the added functional complexity is offset by the elimination of separate fixing mechanisms.

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

3Adaptability or versatility

If the cable tray is designed with downward-extending side walls for battery fixing, then battery pre-fixing is enabled, but the cable tray structure becomes more complex

Engineering Contradiction:
Improvebattery pre-fixing capabilityVSAvoidcable tray structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable tray side walls extend downward in the vertical dimension to create fixing surfaces below the main cable routing level. This dimensional extension enables battery pre-fixing capability without significantly complicating the overall structure, as the downward extension is a natural continuation of the side wall geometry rather than an added component.

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