Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If traditional hydraulic closing hinges are used, then automatic closing function is achieved, but the device becomes bulky and visually unappealing

Engineering Contradiction:
Improveautomatic closing functionVSAvoiddevice bulk
Core Design Contradiction:
Extent of automationVSVolume of moving object

Solution Approach 1:

The patent combines the automatic closing mechanism and hydraulic damping mechanism into a single integrated hinge device. The closing means are incorporated within the hinge structure itself, merging multiple functions (automatic closing, damping, and positioning) into one compact unit, thereby reducing overall device bulk while maintaining all required functions

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hinge device performs multiple functions simultaneously: it provides automatic closing action, hydraulic damping for controlled movement, and adjustable positioning capabilities. This multi-functionality eliminates the need for separate devices, reducing the overall volume and visual bulk while achieving comprehensive door control

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

2Extent of automation

If traditional hydraulic closing hinges are used, then automatic closing is achieved, but closing speed and latch position cannot be adjusted

Engineering Contradiction:
Improveautomatic closingVSAvoidadjustability of closing speed and latch position
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The hinge incorporates adjustable mechanisms that allow the closing speed and latch position to be modified after installation. The hydraulic damping characteristics can be tuned, and the latch position is adjustable, transforming a static device into a dynamic one that adapts to different requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device allows changing of operational parameters such as closing speed and latch position through adjustment mechanisms. By modifying these parameters, the same hinge can adapt to different door weights, sizes, and closing requirements, enhancing versatility

Inventive Principle:
Principle #35Parameter changes

3Extent of automation

If traditional hydraulic closing hinges are used, then closing function is achieved, but the device has large number of parts resulting in difficult manufacturing and high cost

Engineering Contradiction:
Improveclosing functionVSAvoidnumber of constructive parts
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent integrates the closing means and hydraulic damping means into a unified hinge structure, reducing the number of separate components. By merging these functions into fewer parts, manufacturing becomes simpler and assembly is reduced, lowering production costs

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If traditional hydraulic closing hinges are used, then closing control is achieved, but frequent maintenance is required

Engineering Contradiction:
Improveclosing controlVSAvoidmaintenance frequency
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The hinge incorporates features that reduce maintenance requirements, such as sealed hydraulic chambers that prevent contamination and self-lubricating surfaces. The design minimizes wear and tear, allowing the device to operate with minimal intervention and reducing maintenance frequency

Inventive Principle:
Principle #25Self-service

AI summary

A hinge device for rotatably moving a closing element (D), comprising a fix element (11) anchorable to the stationary support structure (S) coupled to a movable element (10) anchorable to the closing element (D) for rotating around a first longitudinal axis (X) between an open position and a closed position. The device further includes at least one slider (20) movable along a respective second axis (Y) between a compressed and an extended position. One between the movable element (10) and the fix element (11) includes at least one operating chamber (30) defining the second axis (Y) so as to slidably house the slider (20), the other element comprising a pivot (40) defining the first axis (X). The pivot (40) and the slider (20) are reciprocally coupled so that to the rotation of the movable element (10) around the first axis (X) corresponds the sliding of the slider (20) along the second axis (Y) and vice versa.
