Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a composite sliding wall uses horizontal and oblique frames with motion transmission means, then automatic closure of trapezoidal-shaped windows or doors is enabled, but device complexity increases

Engineering Contradiction:
Improveautomatic closureVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The composite sliding wall is divided into separate horizontal and oblique frames that can move independently in their respective guides. This segmentation allows each frame to be controlled separately by the motion transmission means, enabling automatic closure while keeping individual components manageable in complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The motion transmission means acts as an intermediary mechanism between the motor and the two frames. It converts the motor's linear motion into coordinated movement of both horizontal and oblique frames, automating the closure process while managing the complexity through a dedicated transmission system

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the composite sliding wall uses motor and gravity actuation, then productivity and automation are improved, but device complexity increases due to multiple actuation systems

Engineering Contradiction:
Improveclosure speedVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system dynamically switches between motor actuation for opening and gravity actuation for closing. The motor provides powered movement in one direction while gravity naturally assists closure in the opposite direction, improving productivity without requiring complex dual-powered systems

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Gravity serves as a self-service actuation mechanism that automatically closes the sliding wall without requiring additional power input. The system leverages the natural gravitational force on the oblique frame to perform the closing function, enhancing productivity while minimizing the need for complex motor control systems

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the composite sliding wall is designed for trapezoidal shape, then adaptability to various applications is improved, but manufacturing precision requirements increase

Engineering Contradiction:
