Power Converter Cover Assembly for Replaceable Display and Radar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenient disassembly of conventional surface covers in power conversion systems leads to potential damage of internal components and affects the waterproof function, compromising the overall integrity of the system.
Innovation Solution
A power conversion system design where the screen display assembly, including a radar and display screen, is mounted on a detachable light transmission assembly, allowing for replacement without disassembling the surface cover, and incorporating a sealing cover and waterproof plugs to maintain system integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the surface cover is disassembled to replace screen display components, then the components can be replaced, but the circuit components inside the PCS may be directly exposed and damaged
Solution Approach 1:
The surface cover is divided into multiple detachable modules: the light transmission assembly (containing screen display components) can be separated from the sealing assembly (containing circuit components). This segmentation allows replacement of display components without exposing internal circuit boards, as the sealing assembly remains intact and attached to the case body.
Solution Approach 2:
The light transmission assembly serves as an intermediary layer between the external environment and the internal circuit components. By designing this assembly as detachable while keeping the sealing assembly fixed, the system enables component replacement through the intermediary structure without directly exposing the protected circuit components inside.
2Ease of repair
If the surface cover is disassembled and reassembled, then component replacement is possible, but the overall airtightness and waterproof function of the PCS case may be affected
Solution Approach 1:
The surface cover is segmented into a fixed sealing assembly and a detachable light transmission assembly. The sealing assembly maintains permanent contact with the case body through sealing structures (sealing rings, adhesive layers), ensuring continuous waterproof protection. Only the non-sealing light transmission assembly is detached for component replacement, preserving the integrity of the waterproof barrier.
Solution Approach 2:
Different regions of the surface cover are assigned different functional qualities: the sealing assembly region maintains high sealing quality with waterproof structures, while the light transmission assembly region allows detachability. This local differentiation enables component replacement in the non-critical light transmission area without compromising the critical sealing function.
3Ease of operation
If the conventional surface cover design is used, then the structure is simple, but it is inconvenient to disassemble and replace components
Solution Approach 1:
The surface cover is divided into modular components (sealing assembly, light transmission assembly, fastening structures) that can be independently manipulated. This segmentation transforms the operation from complex full-disassembly to simple targeted detachment of the light transmission assembly, improving ease of operation while accepting increased structural complexity.

AI summary
Various features herein describe a power conversion system, comprising a case, a screen display assembly, and a light transmission assembly. The case comprises a control board and a surface cover. The screen display assembly may be mounted on the surface cover. The screen display assembly is electrically connected to the control board, and the light transmission assembly covers the screen display assembly and may be mounted on the surface cover. The screen display assembly comprises a radar and a display screen distributed on the surface cover. When disassembling and replacing, a user only needs to remove the light transmission assembly from the surface cover, so radar and/or the display screen can be directly disassembled and replaced, without disassembling the surface cover.
