Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a compressor and refrigerant are used in traditional air conditioners, then cooling function is achieved, but the device becomes heavy and bulky making installation and transportation inconvenient
Solution Approach 1:
The patent replaces the mechanical compressor-based refrigeration system with a thermoelectric cooling chip that uses electrical current to generate cooling effect through the Peltier effect. This substitution eliminates the heavy compressor, condenser, and refrigerant circulation system, dramatically reducing device weight and complexity while maintaining the cooling function.
Solution Approach 2:
The patent changes the fundamental operating principle from mechanical compression of refrigerant to direct electrical-to-thermal energy conversion using thermoelectric materials. By changing the physical parameter of cooling generation from mechanical work to electrical current-driven heat pumping, the system achieves weight reduction without sacrificing cooling capability.
2Reliability
If a compressor is used in traditional air conditioners, then cooling function is achieved, but energy consumption increases significantly
Solution Approach 1:
The patent replaces the high-energy mechanical compressor system with a low-power thermoelectric cooling chip that directly converts electrical energy to cooling effect. This substitution eliminates the energy-intensive mechanical compression, refrigerant circulation, and expansion valve operations, significantly reducing overall energy consumption while maintaining effective cooling.
Solution Approach 2:
The patent extracts and removes the energy-consuming compressor and refrigerant circulation system from the air conditioning device, retaining only the essential cooling function through the thermoelectric chip. By taking out the high-energy components and replacing them with a solid-state cooling solution, the system achieves dramatic energy savings.
3Reliability
If a compressor is used in traditional air conditioners, then cooling function is achieved, but noise is produced
Solution Approach 1:
The patent replaces the noisy mechanical compressor, motor, and refrigerant flow system with a silent solid-state thermoelectric cooling chip. This substitution eliminates mechanical vibrations, motor noise, and refrigerant flow sounds, achieving near-silent operation while maintaining the cooling function through electrical-to-thermal energy conversion.
4Reliability
If refrigerant is used in traditional air conditioners, then cooling function is achieved, but environmental pollution occurs
Solution Approach 1:
The patent extracts and completely removes the refrigerant system from the air conditioning device, eliminating the source of environmental pollution. By taking out the refrigerant circulation system including condenser, expansion valve, and evaporator, the system achieves eco-friendly operation while maintaining cooling function through the thermoelectric chip.
Solution Approach 2:
The patent replaces the refrigerant-based cooling system with a solid-state thermoelectric system that uses no refrigerant. This substitution eliminates greenhouse gas emissions and environmental pollution associated with refrigerant leakage, achieving sustainable cooling through direct electrical-to-thermal energy conversion.

AI summary
The present invention mainly utilizes a specialized semiconductor ship, the so-called thermoelectric cooling chip, for producing the coldness. A cooling circulating member and a heat dissipating member are configured at the two sides of the thermoelectric cooling chip. The coldness produced by the thermoelectric cooling chip is delivered by a cold conduction plate and cooling pipes, and is stored in fins of the cooling circulating member. A temperature controller determines a desired temperature and the coldness stored in the fins are blown out as cool air by a fan. Similarly, the heat produced by the chip is dissipated by the heat dissipating member. As such, the present invention could reach the desired temperature within a short period of time without the conventional compressor. The present invention therefore is easier to install and transport, consumes less power, and produces almost no noise and pollution to the environment.
