Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual air blower is used to clean hinge hole, then cleaning operation can be performed, but it is time-consuming and lacks effectiveness

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidmanual operation time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs self-service cleaning through automated coordination between the exhaust member blowing clean gas and the suction member removing contaminants. The control unit automatically controls the sequence of operations without manual intervention, making the cleaning process self-sufficient and highly efficient.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical air blower operation is replaced by an automated system using compressed clean gas from an exhaust member coupled with a suction member. This substitution eliminates manual labor and significantly improves cleaning effectiveness through coordinated gas flow and vacuum suction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual air blower is used to clean hinge hole, then cleaning can be performed, but it may cause damages to outer surface

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidsurface damage

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Clean gas acts as an intermediary medium to remove contaminants without direct contact between the cleaning tool and the hinge hole interior. The gas flow carries contaminants to the suction member, preventing mechanical contact that could damage the outer surface while maintaining cleaning effectiveness.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses pneumatic principles by introducing compressed clean gas through the exhaust member to blow out contaminants, followed by vacuum suction through the suction member. This pneumatic cleaning method eliminates the need for physical contact tools that could scratch or damage the hinge hole surface.

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Ease of operation

If manual air blower is used, then cleaning operation is simple, but alignment precision is poor

Engineering Contradiction:

Improveoperation simplicityVSAvoidalignment precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The control unit provides automated feedback control by coordinating the exhaust member and suction member operations based on preset parameters. This ensures consistent cleaning effectiveness and proper hinge hole preparation, leading to improved alignment precision without requiring complex manual operations.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Manual air blower operation is replaced by an automated pneumatic system that precisely controls gas flow and suction. This substitution ensures consistent and thorough contaminant removal, improving alignment precision while maintaining ease of operation through automated control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A cleaning device includes a base, a positioning component, and a cleaning component, all mounted on the base. The positioning component includes a fixture and a side pushing member, the side pushing member located alongside the fixture. The side pushing member is used to push a workpiece into a limiting area of the fixture, where the fixture secures the workpiece in place. The cleaning component includes an exhaust member and a suction member. The exhaust member blows gas into contaminated holes, the gas is then sucked by the suction member.
