Under-Seat Electrical Component Tray for Protected EV Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face challenges in protecting inverters and electrical components from splashing rainwater and dust, leading to degradation and making maintenance difficult due to the need to remove heavy storage boxes during repairs.
Innovation Solution
An electric vehicle design with a plate member mounted inside a covered space under the seat, which is drawably guided outside for easy access, allowing the inverters and electrical components to be protected from rainwater and dust while facilitating maintenance without removing the seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrical components are placed in a covered space under the seat, then protection from rainwater and dust is improved, but accessibility for maintenance deteriorates
Solution Approach 1:
The patent applies the dynamics principle by making the plate member movable rather than fixed. The plate member can be drawn out from the covered space under the seat to a position outside the covered space using a guide mechanism, allowing the electrical components to be accessible during maintenance while remaining protected during normal operation. This dynamic positioning resolves the contradiction between protection and accessibility.
2Object-affected harmful factors
If a storage box is used to accommodate electrical components, then protection from environmental factors is improved, but weight and complexity increase
Solution Approach 1:
The patent extracts the electrical components from a traditional storage box structure and mounts them directly on a plate member. This eliminates the need for a separate storage box, reducing weight and structural complexity while maintaining protection through the covered space design. The plate member serves as a simple mounting surface rather than a full enclosure.
3Volume of moving object
If electrical components are mounted in a small space under the seat, then space utilization is improved, but workability for repairs deteriorates
Solution Approach 1:
The plate member is designed to be movable along a guide, allowing it to be drawn out from the compact covered space under the seat to a larger external position. This dynamic movement enables efficient use of limited internal space during normal operation while providing ample workspace for repairs when the plate member is extended outward.
4Ease of repair
If the seat is removed to access electrical components, then accessibility is improved, but device complexity and time increase
Solution Approach 1:
The patent extracts the electrical components from beneath the seat by mounting them on a plate member that can be drawn out independently. This allows access to the components without removing the seat, simplifying the maintenance procedure. The plate member acts as an intermediate extraction mechanism that separates component access from seat removal.

AI summary
An electric vehicle includes a body frame, a seat disposed on the body frame, a wheel attached to the body frame to be driven by an electric motor, a battery to supply electric power to the electric motor via an inverter and an electrical component, a plate member placed inside a covered space with a top being covered and on which the inverter and the electrical component are mounted, and a guide supported by the body frame to drawably guide the plate member from a position inside the covered space to a position outside the covered space.
