Solution Overview
Problem
Existing frozen drink makers lack adaptability and user-specific control over temperature and texture of drink products, leading to inconsistent outcomes.
Innovation Solution
A drink maker system that includes a temperature sensor, cooling circuit, and controller to adjust temperature based on preset recipes, allowing manual user input for fine-tuning, and monitors motor conditions to prevent damage by adjusting cooling when high power is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If automatic temperature control based on preset recipes is used, then temperature consistency is improved, but user-specific customization capability deteriorates
Solution Approach 1:
The system dynamically adjusts the preset temperature by adding a manual temperature adjustment value that users can customize. The controller modifies the target temperature in real-time based on user input, allowing the system to transition from a fixed preset mode to a flexible adaptive mode that accommodates individual preferences while maintaining automated control.
Solution Approach 2:
The system changes the temperature parameter by combining a preset base temperature with a user-adjustable offset. This allows the fundamental temperature setting to be modified according to user-specific requirements while retaining the structured approach of preset recipes, effectively resolving the conflict between consistency and customization.
2Manufacturing precision
If strong cooling is applied to achieve desired texture, then drink product thickness control is improved, but motor power consumption increases
Solution Approach 1:
The system continuously monitors motor current or power during operation and uses this feedback to detect when the drink product becomes too thick. When excessive thickness is detected, the controller automatically adjusts the temperature upward to reduce viscosity, thereby reducing motor power consumption and preventing motor damage while maintaining acceptable drink texture.
Solution Approach 2:
The system proactively monitors motor conditions and adjusts temperature before the motor reaches dangerous power levels. By detecting early signs of excessive thickness through current monitoring, the system can preemptively increase temperature to reduce viscosity, preventing motor overload and damage before they occur.

AI summary
A drink maker includes a mixing vessel arranged to receive a drink product and a dasher, driven by a drive motor, arranged to mix the drink product within the mixing vessel. A cooling circuit is arranged to cool the drink product within the mixing vessel, while a temperature sensor is arranged to detect a temperature associated with the drink product and output a temperature signal, and a memory is arranged to store a recipe including a first temperature value corresponding to a first target temperature. A controller, in communication with the memory, is arranged to: i) receive the temperature signal, and ii) control the temperature associated with the drink product by controlling the cooling circuit based on the received temperature signal, the first temperature value, and a manual temperature adjustment. A user interface is arranged to receive a user input to adjust the manual temperature adjustment.
