Solution Overview
Problem
Existing blenders face issues with safety concerns due to potential operation of the motor when the container is not seated properly, and require manual input for operation selection, lacking the ability to recognize the container type and orientation.
Innovation Solution
A blender design that includes a detection member in the container and a detection device in the body, allowing for motor operation only when the container is correctly seated, and automatically setting operations based on the detected container type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control button for rotation operation is provided on the front surface of the base part, then the blender can be operated according to preset cooking programs with simple user manipulation, but the user has to directly set and input desired operations and select manipulation which is inconvenient
Solution Approach 1:
The detection device automatically detects the container type and orientation without user input, and the controller automatically selects and executes the appropriate cooking program. This self-service mechanism eliminates the need for manual operation selection and setup, resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If the motor can be operated by user manipulation even when the container is not seated on the base part, then the blender is easy to operate, but safety problems occur due to potential operation without proper container seating
Solution Approach 1:
The detection device performs preliminary detection of the container's presence and orientation before the motor is activated. The controller receives the detection signal and only permits motor operation when proper container seating is confirmed. This preliminary action ensures safety while maintaining ease of operation, resolving the technical contradiction.
3Adaptability or versatility
If the detection member is disposed along the circumference of the container coupling portion, then the container can be recognized regardless of mounting direction and state, but the device structure becomes more complex
Solution Approach 1:
The detection member is disposed asymmetrically at a specific angular position relative to the container coupling portion rather than uniformly distributed. This asymmetric positioning, combined with the detection device's ability to identify container orientation, enables recognition of containers in various mounting directions while minimizing the number of detection members needed, thus resolving the contradiction between adaptability and device complexity.
