Solution Overview
Problem
Conventional refrigerators require additional space above the condenser for maintenance and assembly, which reduces the storage space due to the vertical mounting and dismounting requirements, leading to inefficiencies in space utilization within the machine room.
Innovation Solution
A design where the condenser is mounted on a base pan and can be easily assembled and disassembled through a sliding mechanism within the machine room opening, allowing for three-dimensional air flow and minimizing the machine room's height and volume, eliminating the need for extra vertical space during service and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the condenser is mounted in a vertical downward direction, then the condenser can be installed and maintained, but additional vertical space above the condenser is required for service operations
Solution Approach 1:
The condenser is mounted horizontally rather than vertically, changing the mounting dimension from vertical to horizontal. This allows service operations to be performed from the front of the machine room without requiring additional vertical space above the condenser, thus resolving the contradiction between ease of repair and machine room volume.
2Volume of stationary object
If the machine room volume is minimized, then the storage space is maximized, but the space required for condenser assembly and service is reduced
Solution Approach 1:
By mounting the condenser horizontally and positioning its front surface to face the machine room opening, the patent enables service operations to be performed from the front without requiring additional vertical clearance. This dimensional change allows the machine room volume to be minimized while still providing adequate access for condenser assembly and maintenance.
3Ease of manufacture
If the condenser is mounted with downward movement, then the condenser can be installed, but a space equal to the moving distance in the vertical direction is required
Solution Approach 1:
The condenser is mounted to move horizontally into the machine room from the front opening rather than moving vertically downward. This horizontal mounting approach eliminates the need for vertical clearance equal to the condenser's moving distance, thereby reducing the required machine room volume while maintaining ease of installation.
