Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milk beverage heating mixers face challenges in temperature measurement accuracy due to the thermostat being affected by the hot plate's temperature, leading to inefficient heating, poor foaming, and potential safety hazards, especially during continuous use.
Innovation Solution
A milk beverage heating mixer design featuring a temperature measurement assembly that contacts the side wall of the cup via a lever assembly, avoiding direct contact with the heating plate and reducing the impact of waste heat, thus improving temperature measurement accuracy and maintaining the integrity of the heating plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the thermostat penetrates through the hot plate to measure temperature, then the temperature measurement structure is simple, but the temperature measurement accuracy deteriorates due to interference from the hot plate's high temperature
Solution Approach 1:
The temperature measurement function is separated from the heating function. The thermostat is moved from the hot plate to the cup body, dividing the temperature measurement system into an independent component that is not affected by the hot plate's thermal interference, thereby resolving the contradiction between structural simplicity and measurement accuracy.
Solution Approach 2:
The cup body serves as an intermediary medium between the hot plate and the thermostat. By placing the thermostat in the cup rather than in direct contact with the hot plate, the cup acts as a thermal buffer that isolates the temperature sensor from the extreme temperatures of the heating element, enabling accurate measurement without complex shielding structures.
2Ease of manufacture
If through holes are formed in the hot plate for thermostat installation, then the thermostat can be installed, but the heating efficiency deteriorates and safety hazards increase
Solution Approach 1:
The thermostat is extracted from the hot plate structure and relocated to the cup body. This eliminates the need for through holes in the hot plate, preserving the hot plate's integrity and continuous heating surface, thereby maintaining high heating efficiency while avoiding safety hazards associated with holes in the heating element.
3Stability of the object's composition
If the thermostat is affected by the hot plate's high temperature, then the thermostat can remain in position, but the temperature measurement accuracy deteriorates during continuous heating
Solution Approach 1:
The cup body functions as a thermal intermediary that physically positions the thermostat in a location where it can stably measure the milk temperature without being directly exposed to the hot plate's high temperature. This intermediary placement allows the thermostat to remain positioned for stable measurement while avoiding thermal interference that would degrade accuracy during continuous operation.

AI summary
A milk beverage heating mixer comprises a cup, a stirrer, a base, a heating plate, a temperature measurement assembly and a first lever assembly. A cavity for accommodating the cup is formed in an upper end of the base. A first radial opening and a second radial opening are formed in a cavity wall of the cavity. The heating plate is disposed at the bottom of the cavity. The first lever assembly is rotatably disposed outside the cavity, and a protrusion at a first end of the first lever assembly stretches into the cavity via the first radial opening. When accommodated in the cavity, the cup presses the protrusion and pushes the temperature measurement assembly by means of the second end of the first lever assembly to stretch into the cavity via the second radial opening to make contact with a side wall of the cup.
