Solution Overview
Problem
Conventional juice extractors with twin-gear systems face difficulties in easy assembly and disassembly, as well as in preventing operational interruptions due to remnants caught between components, which complicates washing and restarting the extraction process.
Innovation Solution
A juice extractor design featuring a fastening unit with hinge-coupled arms and protrusion portions that allow simultaneous movement, along with a sensor unit to facilitate easy coupling and decoupling, and a reversible motor for efficient operation and remnant management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the housing is separated for washing, then cleaning capability is improved, but the housing cannot be easily separated due to remnants caught between components
Solution Approach 1:
The housing is divided into separable sections that can be easily detached from the driving unit. The fastening unit includes arms that can be opened to release the housing, allowing users to separate the housing for washing without dealing with caught remnants, thus improving ease of separation while maintaining operational continuity through the sensor unit's safety mechanism.
Solution Approach 2:
The sensor unit extracts the safety function from the mechanical coupling system. By mounting sensors on the driving unit and housing that detect separation, the system can stop power application to the driving unit when separated, preventing injuries during housing separation or after separation, thus enabling easy separation without compromising safety.
2Productivity
If the extracting operation continues without interruption, then productivity is improved, but remnants caught between housing and crushing units cause unexpected stoppage
Solution Approach 1:
The fastening unit is designed with arms that can be pre-positioned and quickly opened to separate the housing from the driving unit. This preliminary design of the coupling mechanism allows for rapid separation when remnants are detected, preventing unexpected stoppages and maintaining operational stability while preserving productivity through quick restart capability.
Solution Approach 2:
The sensor unit provides feedback about the coupling state between housing and driving unit. When separation is detected, the sensor unit stops power application to the driving unit, preventing unsafe operation. This feedback mechanism ensures operational stability by responding to separation events while allowing continuous productivity through quick re-coupling and restart.
3Adaptability or versatility
If the fastening unit uses individual arm adjustment, then coupling flexibility is improved, but assembly complexity increases due to position adjustment requirements
Solution Approach 1:
The fastening unit combines two arms into a synchronized system where both arms are hinge-coupled to the driving unit and have protrusion portions that engage simultaneously. This merging of the two-arm operation into a single synchronized action eliminates the need for individual position adjustment, reducing assembly complexity while maintaining coupling flexibility through the hinge-coupled design.
Solution Approach 2:
The protrusion portions on the arms act as intermediaries that automatically align and engage with corresponding features on the housing. This intermediary mechanism eliminates the need for manual position adjustment of individual arms, simplifying assembly while preserving the flexible coupling capability through the hinge-coupled arm design.

AI summary
Disclosed is a juice extractor with an easily assembled and disassembled housing, the juice extractor including: a driving unit having a motor housing having a motor mounted at the inside thereof, a rotary shaft connected to the motor and protruded toward one side of the motor housing, and a fixing shaft disposed adjacent to the rotary shaft on the motor housing; a juice extracting unit having roller portions operated by the motor provided at the driving unit so as to crush, extract and transfer juice extraction materials and the housing for accommodating the roller portions thereinto; a fastening unit for detachably coupling the housing of the juice extracting unit to the motor housing; and a sensor unit having a sensor operator mounted on the housing of the juice extracting unit and a sensor mounted on the motor housing in such a manner as to be operated by a change in distance with the sensor operator. There is no need to adjust the location of the fastening unit when the housing is joined to the driving unit, the roller portions and the housing can be easily separated since the sensor unit is provided at the portions in which the driving unit and the housing face each other, an injury due to the operation of the roller portions can be prevented when the housing is separated, and juicing is effective.
