Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stain removing system uses manual beating action to supply detergent to the stain portion, then the decontamination effect is improved, but hand fatigue occurs due to rapid hand movement
Solution Approach 1:
The patent replaces the manual mechanical beating action with an automatic spraying mechanism that uses a solvent delivery system. The spraying mechanism automatically applies solvent to the stain portion without requiring manual beating, thus eliminating hand fatigue while maintaining effective stain removal through the chemical action of the solvent
Solution Approach 2:
The patent employs a spraying mechanism that uses pneumatic or hydraulic principles to deliver solvent to the stain portion. The solvent is sprayed through a nozzle system that can be positioned near the stain area, providing automatic application without manual intervention and avoiding hand fatigue
2Extent of automation
If a stain removal device integrates spraying mechanism and attracting mechanism with negative pressure fan, then automatic solvent coating and removal is achieved, but the device becomes large and difficult to produce as portable structure
Solution Approach 1:
The patent extracts the attracting mechanism (negative pressure fan) from the integrated system and replaces it with a simpler solvent evaporation and absorption approach. The solvent is applied and then allowed to evaporate or be absorbed by the fabric, eliminating the need for complex suction mechanisms and reducing device size while maintaining automated solvent application
Solution Approach 2:
The patent uses disposable or replaceable solvent cartridges or bottles that can be easily replaced when empty. This approach eliminates the need for complex recycling or recovery systems, significantly reducing device complexity and size while maintaining automated solvent delivery functionality
3Extent of automation
If a washing system uses integrated spraying and attracting mechanisms, then automatic washing treatment is achieved, but the number of components increases making the device large
Solution Approach 1:
The patent designs a multi-functional washing unit that can perform multiple washing treatments (spraying, soaking, rubbing) using a single integrated platform. The unit can accept different types of accessories or attachments that provide various washing functions, reducing the need for separate dedicated devices and minimizing the total number of components while maintaining automated operation
Solution Approach 2:
The patent segments the washing system into modular components: a main control unit and interchangeable accessory modules. Each accessory module can be attached or detached as needed, providing different washing functions (spraying, soaking, heating) without requiring all components to be present simultaneously, thus reducing the number of components in any given configuration while maintaining automation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables automatic performance of various washing treatments, reduces hand fatigue, and increases the range of washable objects, while maintaining a compact and portable design by using interchangeable accessories and a transmission mechanism that adjusts rotational speed.
Implementation Method 1
a motor, which is driven rotationally by means of a power supply
Implementation Method 2
a rotation transmission portion, which is capable of transmitting a rotational force of the motor to the accessories
Implementation Method 3
the transmission mechanism may be a planetary gear mechanism, which comprises a sun gear that is connected to the rotation input portion, a plurality of planetary gears that rotate around the sun gear
Implementation Method 4
a motion direction conversion mechanism, which converts a rotational motion input by the rotation input portion into a linear motion
Implementation Method 5
The supplied detergent is penetrated into the cloth product, and is absorbed into the absorbing sheet together with the dirt constituting the stain portion
