Detachable Bus Bar Layout Above Battery in Multi-Purpose Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-purpose vehicles face complications in wiring between the battery and bus bar due to their positional relationship, and there is a disadvantage when an unnecessary bus bar remains mounted if power does not need to be supplied from the battery.
Innovation Solution
A multi-purpose vehicle design where the bus bar is detachably mounted to a mounting section located above the battery, allowing for simplified wiring and omission of the bus bar when power is not required from the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bus bar is permanently mounted to supply power from the battery, then power supply function is ensured, but the device complexity increases and unnecessary components remain when power is not needed
Solution Approach 1:
The bus bar mounting structure is segmented into detachable components: a mounting section fixed to the vehicle body and a bus bar that can be attached or removed from this section. This segmentation allows the bus bar to be permanently mounted when power supply is needed (ensuring reliability) while enabling its removal to reduce device complexity when power supply is not required
Solution Approach 2:
The mounting structure transitions from a static permanent mounting to a dynamic configurable state. The bus bar can be in a mounted state (when power supply is needed) or a removed state (when not needed), providing adaptability that resolves the contradiction between ensuring power supply function and reducing device complexity
2Adaptability or versatility
If the bus bar is positioned away from the battery, then mounting flexibility is improved, but wiring complexity increases
Solution Approach 1:
The mounting section is positioned in close proximity to the battery, creating an optimal electrical connection point. This positioning minimizes the wiring path length and simplifies the wiring configuration while still allowing the bus bar to be mounted at a convenient location on the vehicle body, thus balancing mounting flexibility with wiring simplicity

AI summary
A vehicle body includes a pair of left and right body frames 2, a battery 15 for supplying power to an optional device retrofittable to the vehicle body, and a mounting section 31 to which a bus bar 30, which is for supplying current from the battery 15 to the optional device, is detachably mountable. The bus bar 30 is located above the battery 15 while mounted to the mounting section 31.
