Innovation Solution
A controller for a cool and warm dual system with a design that includes a bottom housing, a water tank, a heater, cooling end heat exchangers, cooling plates, semi-circular heat sinks, and obliquely positioned cooling fans, allowing for efficient heating and cooling operations by circulating water through the mattress via outlet and return pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple heating system is used, then the device complexity is reduced, but the cooling and heating effects are insufficient
Solution Approach 1:
The patent combines both cooling and heating functions into a single integrated system. The controller includes both a heater and cooling end heat exchangers within the same water tank structure, allowing the mattress system to provide both heating and cooling effects through one unified device rather than separate systems, thereby improving reliability without proportionally increasing complexity.
Solution Approach 2:
The water tank serves multiple functions: it stores water for circulation, houses the heater for heating mode, accommodates cooling end heat exchangers for cooling mode, and includes water level sensing capabilities. This multi-functionality allows a single component to perform various operations, enhancing system reliability while controlling overall complexity.
2Device complexity
If cooling fans are positioned horizontally, then the structure is simpler, but the heat dissipation efficiency is reduced
Solution Approach 1:
The cooling fans are positioned obliquely (at an angle) rather than horizontally, creating an asymmetric arrangement. This oblique positioning allows the fans to better utilize the inclined notches in the heat sinks, improving the airflow path and heat dissipation efficiency by directing air flow more effectively across the heat exchange surfaces.
Solution Approach 2:
The cooling fans are arranged in a vertical dimension within the inclined notches of the heat sinks rather than only horizontal placement. This three-dimensional arrangement optimizes the airflow direction and enhances heat dissipation by utilizing vertical space and creating more effective air circulation patterns around the heat exchanger surfaces.

AI summary
A controller for cool and warm dual system includes a bottom housing and the top housing, a water tank is provided in the bottom housing, a heater is provided in the water tank, and a tank cover is arranged on the water tank. Accommodating slots are defined in and extend through two sidewalls of the water tank along its width direction, respectively. The accommodating slots each accommodate a cooling end heat exchanger that extends into the water tank. Outer sides of the cooling end heat exchangers are respectively provided with a cooling plate, and outer sides of the cooling plates are respectively provided with a semi-circular shaped heat sink. Opposite sides of the heat sinks away from each other each define an inclined notch therein. Cooling fans matching with the notches are arranged in the notches, respectively. The cooling fan is set obliquely, and attaches to the heat sink.
