Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the heating heat exchanger and cooling heat exchanger continuously generate warm air and cold air respectively, then the air conditioning unit can maintain continuous operation, but the cooling performance deteriorates due to continuous discharge of warm air in cooling mode and heating performance deteriorates due to continuous discharge of cold air in heating mode
Solution Approach 1:
The patent extracts and separates the waste heat treatment function from the main air conditioning unit by introducing an independent waste heat treatment device. This device specifically handles the warm air from the heating heat exchanger in cooling mode and cold air from the cooling heat exchanger in heating mode, removing the harmful thermal effects that deteriorate performance while allowing continuous operation of the main unit.
Solution Approach 2:
The patent converts the harmful waste heat (warm air in cooling mode, cold air in heating mode) into a beneficial resource by using the waste heat treatment device to pre-condition the air. The warm air that would otherwise degrade cooling performance is used to pre-heat incoming air, and the cold air that would degrade heating performance is used to pre-cool incoming air, thereby improving overall system efficiency.
2Stability of the object's composition
If the air conditioning unit is fixedly installed in the air conditioner main body, then the structure is stable and simple, but the mobility is limited and the air conditioner cannot be moved to different locations
Solution Approach 1:
The patent segments the air conditioning system into two independent parts: a stationary air conditioner main body and a movable air conditioning unit. The air conditioning unit can be detached from the main body and moved to different locations within the room, providing mobility while the main body remains stable and fixed. This segmentation allows the system to adapt to different spatial requirements.
Solution Approach 2:
The patent introduces a movable mounting structure with guiding rails and movable guides that enable the air conditioning unit to dynamically reposition itself along the wall or ceiling. The unit can move between fixed and movable states, transitioning from a stable installed position to a relocatable configuration, thereby achieving both structural stability when installed and mobility when needed.
3Adaptability or versatility
If the air conditioning unit is made bulky to include all necessary components, then the functionality is complete, but the ease of movement and portability is reduced
Solution Approach 1:
The patent designs the air conditioning unit with universal functionality by integrating both heating and cooling capabilities in a compact configuration. The unit can operate independently or in conjunction with the main body, and the waste heat treatment device serves multiple purposes by handling both warm and cold air streams. This multi-functionality reduces the need for separate units while maintaining portability.
