Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the volume of heat exchangers is increased to improve energy efficiency, then energy efficiency improves, but the installation space becomes insufficient
Solution Approach 1:
The patent utilizes vertical space by implementing a multi-level floor assembly structure where heat exchangers are arranged at different heights on the dividing floor. This dimensional approach allows larger volume heat exchangers to be installed without increasing the horizontal footprint, thereby improving energy efficiency while accommodating limited installation space.
Solution Approach 2:
The floor assembly is segmented into multiple levels with a dividing floor that creates distinct installation zones. Heat exchangers are partitioned and positioned on different levels, allowing optimized space utilization and enabling larger heat exchanger volumes to be accommodated within the constrained overall installation envelope.
2Productivity
If different sized heat exchangers are used to optimize performance, then performance improves, but manufacturing complexity increases
Solution Approach 1:
The dividing floor is designed as a universal platform with standardized support structures and mounting interfaces that can accommodate heat exchangers of various sizes and configurations. This universal design allows different sized heat exchangers to be installed using the same base structure, optimizing performance while minimizing manufacturing complexity.
Solution Approach 2:
While maintaining a standardized overall floor assembly structure, the patent allows for local variations in the form of adapter components and adjustable support elements. These localized adaptations enable customization for different heat exchanger sizes without requiring complete redesign of the entire manufacturing system, thus balancing performance optimization with manufacturing simplicity.
3Ease of manufacture
If a standardized dividing floor is used for all heat pump configurations, then manufacturing costs decrease, but adaptability to different heat pump sizes is reduced
Solution Approach 1:
The standardized dividing floor incorporates dynamic adjustment mechanisms such as adjustable support legs, movable mounting brackets, and configurable adapter components. These dynamic elements allow the standardized structure to adapt to different heat pump sizes and configurations, maintaining manufacturing cost efficiency while providing the necessary versatility.
Solution Approach 2:
The patent introduces intermediary adapter components that serve as mediators between the standardized dividing floor and various heat pump configurations. These adapter elements bridge the gap between the fixed standardized structure and the variable heat pump sizes, enabling cost-effective standardized manufacturing while maintaining adaptability to different applications.

Implementation Method 1
The heat exchanger (evaporator) that cools and dehumidifies the process air exiting the drying chamber and a heat exchanger (condenser) that heats the process air to be supplied to the drying chamber. Part of the moisture contained in the process air condenses on the evaporator.
Implementation Method 2
a heat exchanger (condenser) that heats the process air to be supplied to the drying chamber
Implementation Method 3
The evaporation of the refrigerant takes place mainly in the evaporator of the heat pump. The refrigerant then travels as a gas to a compressor in the heat pump, where it is compressed.
Implementation Method 4
The compressed refrigerant travels from the compressor to the condenser of the heat pump, where it liquefies while releasing heat.
Implementation Method 5
The refrigerant then travels as a gas to a compressor in the heat pump, where it is compressed. The compressor is also the engine that drives the refrigerant through the closed circuit.
Implementation Method 6
The liquefied refrigerant passes from the condenser into an expansion element, in particular a valve, an orifice or a capillary, in which the internal pressure of the refrigerant is reduced and in which the refrigerant is already partially converted back into gas.
