Solution Overview
Problem
Existing food processors with cooling devices, such as those using Peltier elements, require complex and large separate cooling circuits with electric pumps, making them cumbersome and inefficient for cooling preparation vessels.
Innovation Solution
A double-walled preparation vessel design with a Peltier cooling device and phase change material (PCM) between the inner and outer walls, where the PCM absorbs heat from the cooling device and transfers it to the outer wall, eliminating the need for an electric pump-driven cooling circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate cooling circuit with electric pump is used to cool the preparation vessel, then the cooling function is achieved, but the device complexity and size increase
Solution Approach 1:
The cooling device is integrated directly into the vessel wall structure, merging the cooling function with the vessel itself. The double-walled design incorporates the cooling device between the inner and outer walls, eliminating the need for a separate cooling circuit and pump system.
Solution Approach 2:
The cooling circuit and electric pump are extracted and removed from the system. Instead of using a separate cooling circuit, the invention uses a phase change material that passively absorbs heat through phase transition, eliminating the need for active pumping and complex circuitry.
2Quantity of substance
If a phase change material is used to store heat energy, then the heat storage capacity increases significantly, but the device structure becomes more complex
Solution Approach 1:
The phase change material is nested within the double-walled vessel structure. The inner wall, cooling device, phase change material, and outer wall are arranged in a nested configuration where the phase change material is contained within the intermediate space between the inner and outer walls, integrating heat storage into the existing vessel architecture.
3Adaptability or versatility
If the cooling device is integrated into the vessel wall, then the vessel becomes self-sufficient, but the manufacturing complexity increases
Solution Approach 1:
The vessel wall is segmented into distinct functional layers: inner wall, cooling device, phase change material, and outer wall. This segmentation allows each component to be manufactured separately and then assembled, simplifying the overall manufacturing process while maintaining the integrated cooling 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
This design allows for efficient cooling of the preparation vessel without a complex cooling circuit, enabling the vessel to be self-sufficient and ready for use with either a base unit or standalone power supply, while effectively managing thermal energy storage and release.
Implementation Method 1
The cooling device is in thermally conductive contact with the inner wall and a phase change material (PCM, phase change material) is arranged between the cooling device and the outer wall
Implementation Method 2
a phase change material (PCM, phase change material) whose absorbable amount of heat energy in the range of the transition temperature characteristic of the phase change material is significantly greater than an amount of heat energy, which can be stored due to the specific heat capacity of the phase change material outside of the phase change effect
Implementation Method 3
the phase change material being a latent heat storage material whose absorbable amount of heat energy in the range of the transition temperature characteristic of the phase change material
Implementation Method 4
The cooling device transfers the heat energy taken from the preparation space to the phase change material
