Air-conditioning outdoor machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a top cover and wall housing in air-conditioning outdoor machines complicates maintenance and exposes junction boxes to the weather, posing safety hazards due to potential water ingress and aesthetic issues.
Innovation Solution
The design incorporates a removable top sub-plate with an observation window, cable-control-arrangement-structure, and fan-support-assembling-region, along with a support structure between the bottom and top sub-plates, enhancing maintenance accessibility and protecting internal components from weather elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the top cover and wall housing are integrally combined, then the appearance is improved, but maintenance becomes complicated and difficult
Solution Approach 1:
The patent divides the top cover and wall housing into separate, modular components. The top cover can be independently removed to access internal components for maintenance, while the wall housing remains fixed. This segmentation allows the appearance to remain intact when assembled while enabling easy maintenance access when disassembled.
2Ease of operation
If the junction box is exposed on the external side surface, then accessibility is improved, but safety hazards increase due to weather exposure
Solution Approach 1:
The patent places the junction box inside a protective cavity formed within the wall housing structure, rather than exposing it on the external surface. The junction box is nested within the housing, accessible through designated openings or removable panels, which protects it from direct weather exposure while maintaining operational accessibility.
3Adaptability or versatility
If the top sub-plate is designed with multiple functional regions, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent designs the top sub-plate to serve multiple functions: it acts as a structural support element, provides an observation window for monitoring internal components, includes a cable control arrangement structure for wire management, and defines the fan support assembling region. By making the top sub-plate multi-functional, the patent reduces the need for separate components, thereby managing complexity while enhancing functionality.
