Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional hinges are used for rotating doors and shutters, then the hinge provides basic rotational movement, but the hinge becomes cumbersome and aesthetically unappealing with large dimensions

Engineering Contradiction:
Improvehinge dimensionsVSAvoidbraking and damping capability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent applies hydraulic damping principles by introducing a working chamber containing hydraulic fluid and a plunger element. The plunger includes ducts with adjustment means that control fluid flow between compartments, providing adjustable braking and damping effects. This hydraulic mechanism enables compact hinge design with effective motion control, resolving the contradiction between small dimensions and reliable braking capability.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Ease of operation

If conventional hinges with braking means are used, then the hinge provides opening and closing control, but the hinge becomes cumbersome and difficult to mount

Engineering Contradiction:
Improveopening and closing controlVSAvoidhinge structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the braking mechanism, damping system, and rotational movement control into a single integrated hydraulic chamber. The plunger element with its ducts and adjustment means combines multiple functions (braking, damping, speed control) in one compact component. This integration reduces overall device complexity while maintaining comprehensive opening and closing control capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic control through adjustment means that modify the flow characteristics of hydraulic fluid in real-time. The adjustment means can change the effective flow area of the ducts, allowing dynamic adaptation of braking and damping forces according to operational requirements. This dynamic capability provides versatile control without requiring multiple separate mechanisms.

Inventive Principle:
Principle #15Dynamics

3Speed

If the hinge uses hydraulic damping with adjustable ducts, then the rotation speed can be controlled, but the manufacturing complexity increases

Engineering Contradiction:
Improverotation speed of closing elementVSAvoidhinge manufacturing
Core Design Contradiction:
SpeedVSEase of manufacture

Solution Approach 1:

The plunger element serves multiple functions: it acts as a sealing element, a flow control component with integrated ducts, and an adjustment mechanism carrier. The adjustment means, which may be a simple screw or plug, provides universal speed control for both opening and closing operations. This multi-functionality reduces the number of separate parts and simplifies manufacturing processes while maintaining precise rotation speed control.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A hinge for the rotatable movement of a door or a similar closing element anchored to a wall or a similar stationary support includes a fixed element adapted to be coupled to the wall or a similar stationary support and a movable element adapted to be coupled to the door or a similar closing element. The fixed and movable elements are coupled to mutually rotate around a first longitudinal axis between an open position and a closed position.
