Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional food processing devices are manually operated, then portability is improved, but processing efficiency deteriorates
Solution Approach 1:
The patent introduces a coupling unit as an intermediary component that connects the driver to the gearbox and immersion blender. This coupling unit includes a slidable member that engages with the driver's rotating element, allowing the driver's rotational motion to be transmitted through the gearbox to drive the immersion blender and processing blade, thereby converting manual operation into efficient mechanical processing while maintaining portability
2Weight of moving object
If battery operated devices are used, then portability is improved, but device complexity deteriorates
Solution Approach 1:
The patent designs the food processing device to be compatible with multiple types of drivers, including both battery-operated and electrically powered options. The coupling unit is designed to interface with different driver types through standardized engagement features, allowing the same processing mechanism to work with various power sources, thus maintaining portability while avoiding the need to design separate systems for different power types
3Ease of operation
If a coupling unit with slidable member is used, then ease of operation is improved, but device complexity deteriorates
Solution Approach 1:
The coupling unit incorporates a slidable member that can dynamically adjust its position along the axis of the driver's rotating element. This slidable component features engagement protrusions that can lock into corresponding grooves on the driver, providing automatic engagement and disengagement capabilities. The dynamic sliding mechanism allows for easy connection and separation of the coupling unit from the driver, improving ease of operation while keeping the added complexity minimal through simple linear motion
