Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual shaft configuration is used to rotate at high and low speeds, then both mixer and juicer functions can be achieved, but noise and waterproofing problems occur due to interference between the two shafts
Solution Approach 1:
The patent merges the high-speed and low-speed shafts into a single integrated output shaft structure. The clutch mechanism selectively engages different portions of this unified shaft to achieve high-speed mixing or low-speed juicing, eliminating the interference and noise problems caused by separate dual shaft configurations while maintaining both appliance functions.
Solution Approach 2:
The single output shaft is designed with multi-functional capability, serving both high-speed rotation for mixing and low-speed rotation for juicing through the clutch mechanism. This universal shaft design eliminates the need for separate shafts, reducing structural complexity and avoiding the harmful effects of dual shaft interference.
2Adaptability or versatility
If a dual shaft configuration is used to rotate at high and low speeds, then both mixer and juicer functions can be achieved, but waterproofing problems occur due to interference between the two shafts
Solution Approach 1:
The patent merges the high-speed and low-speed shafts into a single integrated output shaft structure. The clutch mechanism selectively engages different portions of this unified shaft to achieve high-speed mixing or low-speed juicing, eliminating the interference and noise problems caused by separate dual shaft configurations while maintaining both appliance functions.
3Object-generated harmful factors
If a single output shaft is used to rotate at high or low speed, then noise and waterproofing issues are resolved, but a mechanism is needed to switch between high and low speed rotation
Solution Approach 1:
The clutch mechanism acts as an intermediary device that selectively engages different transmission paths within the single output shaft. By using this mediator component, the system can switch between high-speed and low-speed rotation modes without requiring complex dual shaft configurations, thereby reducing noise while maintaining functional versatility.
4Volume of moving object
If a single output shaft is used to rotate at high or low speed, then the device structure becomes more compact, but a clutch mechanism is required to enable speed switching
Solution Approach 1:
The patent merges the high-speed and low-speed shafts into a single integrated output shaft structure. The clutch mechanism selectively engages different portions of this unified shaft to achieve high-speed mixing or low-speed juicing, eliminating the interference and noise problems caused by separate dual shaft configurations while maintaining both appliance functions.
Solution Approach 2:
The clutch mechanism and speed switching components are nested within the single output shaft structure, allowing the speed switching functionality to be integrated compactly without requiring additional external mechanisms. This nesting approach maintains device compactness while enabling high-speed and low-speed rotation modes.

Implementation Method 1
a clutch that moves up-down, and when moving downward, engages with a rotor shaft top gear formed on a motor shaft of the drive motor
Implementation Method 2
a reduction gear that is gear-engaged between the rotor shaft gear and the output shaft gear, to reduce a rotational speed of the output shaft gear compared to a rotational speed of the motor shaft
Implementation Method 3
a rotor shaft gear that is inserted into the motor shaft to rotate together with the motor shaft, and is elastically supported so that when the clutch moves downward, contacts with the clutch, to move downward
