Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles equipped with traction batteries face challenges in reducing total weight, which directly affects the driving range due to the space and weight occupied by electronics units.
Innovation Solution
The integration of a mechanical connection interface on the housing of the electronics unit allows it to serve as a structural component for mechanically supporting a seat element, thereby reducing the need for additional structural components and minimizing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronics unit is added to the vehicle for battery management, then the battery control functionality is improved, but the vehicle total weight increases
Solution Approach 1:
The patent combines the electronics unit housing with a structural support function by integrating a mechanical connection interface directly into the housing. This allows the housing to serve dual purposes: protecting electronic components and providing structural support for seat elements, thereby eliminating the need for separate structural components and reducing overall vehicle weight.
Solution Approach 2:
The housing of the electronics unit is designed with multi-functionality, serving both as a protective enclosure for electronic components and as a structural support element for seat mounting. This universal design allows a single component to fulfill multiple functions, reducing the total number of parts and vehicle weight.
2Reliability
If an electronics unit is added to the vehicle for battery management, then the battery control functionality is improved, but the vehicle space is reduced
Solution Approach 1:
The patent merges the electronics unit housing with structural support functionality, allowing the same space to serve dual purposes. The housing provides both electronic component protection and structural support for seat elements, thereby maximizing space utilization without sacrificing either function.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously serves as a protective enclosure and a structural support element. This universal design optimizes space utilization by eliminating redundant structural components.
3Strength
If additional structural components are added to support seat elements, then the mechanical stability is improved, but the vehicle total weight increases
Solution Approach 1:
The patent eliminates the need for separate structural support components by integrating the mechanical connection interface directly into the electronics unit housing. The housing itself is designed to bear mechanical loads from seat elements, thereby providing structural support without adding extra components.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously provides electronic component protection and structural support for seat elements. This universal design achieves mechanical stability while minimizing vehicle weight by using a single component for both functions.
