Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle seat mounting structure compromises stability as the seat is positioned above a battery case, requiring elongated support legs, which can impair stability.
Innovation Solution
A vehicle seat mounting structure that includes a reinforcing structure on the top side of the battery case connected to the seat, enhancing the rigidity of the battery case and supporting the seat with improved stability, while also allowing for efficient arrangement of the battery and electronic control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the seat is positioned above the battery case using elongated support legs, then space efficiency is improved, but stability deteriorates
Solution Approach 1:
A reinforcing structure is introduced as an intermediary component between the battery case and the seat. This reinforcing structure includes reinforcing members that extend along the upper surface of the battery case and are connected to one another, providing additional support and stability to the seat while maintaining the space-efficient configuration.
Solution Approach 2:
The reinforcing structure extends in the lateral direction (width dimension) across the battery case, rather than only vertically. By adding lateral reinforcement members that connect across the width of the battery case, the structure gains stability without increasing vertical height, thus maintaining space efficiency while improving seat support stability.
2Stability of the object's composition
If the reinforcing structure is added to improve rigidity, then seat stability is improved, but device complexity increases
Solution Approach 1:
The reinforcing structure serves multiple functions simultaneously: it reinforces the upper surface of the battery case to improve rigidity, provides additional support points for the seat, and creates a stable platform for mounting electronic control devices. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.
3Volume of moving object
If the battery and electronic control devices are arranged under the seat, then space efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The mounting structure is segmented into distinct functional zones: the battery case housing the battery, the reinforcing structure with its frame of members, and the electronic control devices mounted on the reinforcing structure. This segmentation allows each component to be manufactured and assembled separately, simplifying the overall manufacturing process while achieving efficient space utilization under the seat.
