Battery Pack Mounting Brackets for Wiring Harness Elevation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electrified vehicles, the limited hand clearance along the lateral sides of the battery pack makes it difficult to connect wiring harness connectors to battery arrays, necessitating a solution to improve accessibility and retention of internal components while maintaining clearances.
Innovation Solution
The use of mounting brackets that elevate internal components, such as wiring harnesses, by securing them to a retainer device via fasteners or flexible clip arms, providing dual clearances and facilitating connector connections within the battery pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If internal components are retained at lower positions in the battery pack, then component retention is achieved, but hand clearance and connector accessibility deteriorate
Solution Approach 1:
The mounting bracket utilizes the Z-axis (vertical dimension) to elevate the wiring harness from the lateral side plane to an upper position. This dimensional transition creates hand clearance and connector accessibility without compromising retention, as the bracket anchors the component securely to the battery pack structure at the elevated position.
Solution Approach 2:
The mounting bracket serves as an intermediary component between the wiring harness and the battery pack structure. It provides the necessary support and retention while positioning the wiring harness at an elevated location that improves hand clearance and connector accessibility.
2Ease of operation
If mounting brackets are used to elevate components, then hand clearance and accessibility improve, but device complexity increases
Solution Approach 1:
The mounting bracket performs multiple functions simultaneously: it retains the wiring harness to the battery pack structure, elevates the component to improve hand clearance, and positions connectors for better accessibility. This multi-functionality reduces the need for separate retention and positioning mechanisms.
Solution Approach 2:
The mounting bracket combines retention and positioning functions into a single integrated component. Rather than using separate retention clips and positioning supports, the bracket merges these functions, reducing overall device complexity while achieving the desired elevation and accessibility.
3Volume of moving object
If components are positioned closer to lateral sides, then space utilization improves, but connector accessibility deteriorates
Solution Approach 1:
The mounting bracket resolves the spatial conflict by transitioning the wiring harness from the lateral dimension to the vertical dimension. This allows components to remain space-efficient in the lateral arrangement while gaining vertical clearance for hand access and connector manipulation.

AI summary
This disclosure details exemplary battery pack designs for use in electrified vehicles. An exemplary battery pack may include an enclosure assembly, one or more battery arrays housed within the enclosure assembly, a first battery internal component (e.g., an array holding device, heat exchanger plate, tray, etc.) adjacent to the battery array, a mounting bracket mounted to the first battery internal component, and a second battery internal component (e.g., a wiring harness of an electrical distribution system) elevated above the first battery internal component by the mounting bracket.
