Outdoor Unit Control Box Layout for Easier Air Conditioner Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The maintenance of outdoor air conditioner units is complicated due to chaotic wire arrangements and the need to remove multiple side plates, making the process time-consuming and laborious.
Innovation Solution
The outdoor unit design features a wire mounting plate sheet metal below the main control board and filter board, with the electric control board disposed on this plate, allowing for sequential arrangement of wiring sockets, signal line terminal blocks, and power line terminal blocks, enabling maintenance with the removal of only one side plate and reducing wire crossing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connecting wires are crossed and arranged chaotically in the electric control box assembly, then the wiring can be completed, but the maintenance difficulty increases
Solution Approach 1:
The patent segments the electric control box assembly into modular components with designated wire mounting plates for different wire types (power wires, signal wires, ground wires). This segmentation organizes the chaotic wiring into structured, maintainable sections while still achieving complete wiring coverage.
Solution Approach 2:
The patent introduces wire mounting plates as intermediary components between the connecting wires and the electric control box interior. These mounting plates serve as organized intermediaries that guide and secure wires in specific locations, preventing chaotic arrangement while maintaining wiring completeness.
2Ease of operation
If at least two side plates of the outdoor unit are detached during maintenance, then the electric control assembly can be accessed, but the maintenance process becomes time-consuming and laborious
Solution Approach 1:
The patent extracts the wire mounting plates and electric control boards as separately accessible components within the electric control box assembly. This extraction allows maintenance personnel to access and work on specific control components without necessarily removing multiple side plates, reducing maintenance time and effort.
3Ease of repair
If multiple back plates of the outdoor unit are removed for maintenance, then the electric control components can be accessed, but the disassembly process becomes complicated
Solution Approach 1:
The patent segments the electric control box assembly into independently accessible modules (wire mounting plates, electric control boards) that can be reached through simplified access paths. This segmentation reduces the need to remove multiple back plates, simplifying the disassembly process while maintaining access to all necessary components.
