Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers using the pair gear method face safety risks due to the coupling of grinding and drive parts, which can lead to unexpected operations and accidents during juice extraction.
Innovation Solution
A juicer design that automatically attaches and detaches the drive part and roller part through normal and reverse motor rotation, utilizing a sensor system to control the motor's operation and ensure safe coupling and decoupling, thereby preventing accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grinding part and drive part are coupled to drive the juicer uniformly, then the juicer operates smoothly, but safety accidents may occur due to unexpected operations
Solution Approach 1:
The juicer is divided into separable components: a drive part containing the motor and a roller part containing the grinding mechanism. These parts can be detached from each other, allowing the grinding part to be separated when not in use, thereby eliminating the risk of unexpected operations while maintaining smooth operation when coupled during normal use.
Solution Approach 2:
The motor is designed to automatically rotate in reverse to detach the roller part from the drive part after juicing is complete. This self-service mechanism ensures automatic separation without requiring user intervention, preventing safety accidents while maintaining operational convenience.
2Reliability
If the roller part is detachably coupled to extend forward from the motor housing, then safety is improved through automatic attachment and detachment, but device complexity increases
Solution Approach 1:
The coupling mechanism utilizes the motor's own rotation (both forward and reverse) to automatically attach and detach the roller part. The motor serves dual purposes: driving the juicing operation and controlling the attachment/detachment sequence, thereby improving safety without requiring additional complex control systems or mechanisms.
Solution Approach 2:
The attachment and detachment functions are merged into the motor's operational cycles. The same motor that drives the juicing process forward also reverses to detach the roller part, combining multiple functions into a single component and avoiding the need for separate attachment/detachment mechanisms.
3Reliability
If a sensor system is used to control motor operation for automatic attachment and detachment, then safety is enhanced, but device complexity and cost increase
Solution Approach 1:
A sensor detects the position or state of the roller part relative to the drive part and provides feedback to the control system. This feedback enables the controller to automatically initiate motor rotation in the appropriate direction based on the detected state, achieving safe automatic attachment and detachment through a relatively simple sensor-feedback-loop mechanism.
Solution Approach 2:
The manual mechanical coupling and decoupling process is replaced with an automated system using sensors and motor control. Instead of requiring physical manipulation by the user, the sensor detects the state and the motor automatically performs the attachment or detachment, reducing mechanical complexity while enhancing safety control.
