Controller for cool and warm dual system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cool and warm dual systems for mattresses suffer from insufficient cooling and heating effects due to inefficient switching between cooling and heating processes.
Innovation Solution
A controller for the cool and warm dual system is designed with a bottom housing and top housing, a water tank, a heater, and heat exchangers with semi-circular heat sinks and obliquely positioned cooling fans, allowing for effective circulation of heated or cooled water through the mattress, enhancing both heating and cooling capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing cool and warm dual system switches between cooling and heating processes, then the system can provide both cooling and heating functions, but the cooling and heating effects are insufficient
Solution Approach 1:
The system is segmented into independent cooling and heating modules. The cooling module includes cooling fans and heat sinks, while the heating module includes heating elements and insulation structures. These modules can operate independently or simultaneously, allowing the system to provide both cooling and heating functions without compromising the effectiveness of either function.
Solution Approach 2:
The patent combines both cooling and heating systems into a single integrated controller unit. The controller merges the control of heating elements, cooling fans, heat sinks, and insulation mechanisms into one unified system, enabling simultaneous operation of both functions and improving overall cooling and heating effects compared to separate systems.
2Adaptability or versatility
If the system provides both cooling and heating functions simultaneously, then the dual control capability is achieved, but the structural complexity increases
Solution Approach 1:
The controller is designed as a universal device that performs multiple functions - both cooling and heating - through integrated components. The same water circulation system, pump, and control unit serve both heating elements and cooling fans/heat sinks, reducing the need for separate independent systems and thereby managing structural complexity while maintaining dual functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The controller achieves efficient heating up to 22-70 degrees and cooling up to 12-25 degrees, providing improved dual control functions by utilizing heat exchangers, cooling plates, and fans to circulate and dissipate heat effectively.

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.
