Juice extractor capable of serving as mixer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing appliances for mixing and juice extraction are inefficient due to the need for separate devices with high-speed mixing blades and low-speed screws, which cannot be easily integrated into a single appliance.
Innovation Solution
A dual-shaft system with two high-speed motors, one for a high-speed driving shaft and another for a low-speed driving shaft, using a reducer to adjust the speed, allowing for interchangeable mixer and juice-extraction modules in a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single appliance integrates both mixer and juice extractor functions, then versatility is improved, but device complexity increases due to needing both high-speed and low-speed rotation capabilities
Solution Approach 1:
The appliance is divided into separate functional modules: a high-speed mixer module with a rotary blade and a low-speed juice extraction module with a screw. These modules can be independently attached or removed from the main body, allowing the device to perform different functions without requiring a complex integrated mechanism that simultaneously handles both high-speed and low-speed operations.
Solution Approach 2:
The main body of the appliance is designed with universal compatibility to accept both the mixer module and the juice extraction module. The dual-shaft system with independent motor control provides universal rotational capability that can drive either module, making the base unit multi-functional while keeping each module relatively simple in design.
2Reliability
If two separate appliances are used for mixing and juice extraction, then functional performance is maintained, but loss of time increases due to switching between devices
Solution Approach 1:
The mixer and juice extractor functions are merged into a single appliance by providing a common main body with a dual-shaft rotation system that can accommodate both the mixer module and the juice extraction module. This allows users to switch between functions by simply changing modules rather than switching between separate appliances, eliminating time loss while maintaining the functional performance of each operation.
3Power
If high-speed motors are used for both mixing and juice extraction, then power is sufficient for mixing, but manufacturing precision deteriorates because juice extraction requires low-speed rotation
Solution Approach 1:
The appliance employs a dynamic rotation speed control system where the main body includes a dual-shaft mechanism with independent motor control. The system can dynamically adjust rotation speed based on the attached module: high-speed rotation for the mixer module and low-speed rotation for the juice extraction module. This dynamic adaptability ensures both sufficient power for mixing and precise speed control for juice extraction without compromising manufacturing precision.
