Solution Overview

Problem

Existing hinges lack a facility for easy height adjustment of closures relative to an opening, limiting their ability to properly align with dust seals and other components.

Innovation Solution

A hinge design incorporating a movable element with pivot coupling and adjustment means, including screw-threaded fixing elements and bifurcated portions, allows for angular adjustment and height positioning of the closure relative to the opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjustable links are used to enable left-right and in-out adjustment of the closure, then the closure can be positioned correctly relative to the opening plane, but there is no facility for height adjustment of the closure

Engineering Contradiction:
Improveadjustment capabilityVSAvoidhinge construction
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The movable element is divided into a first part and a second part that can be pivotally coupled together. This segmentation allows independent adjustment of each part, enabling height adjustment capability while maintaining the existing adjustable link structure for lateral positioning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge incorporates adjustable links that can dynamically change length or position, allowing the closure to be adjusted in multiple directions including height. The dynamic adjustability is achieved through mechanisms that permit modification of the link geometry during installation and use.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If the closure is mounted on fixed hinges, then the structure is simple and stable, but the closure cannot be adjusted to ensure correct closed position and alignment with dust seals

Engineering Contradiction:
Improvealignment precisionVSAvoidhinge construction
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The hinge allows preliminary adjustment of the closure position before final mounting is completed. The adjustable links and pivotally coupled parts enable the closure to be positioned and aligned with dust seals and other components before being secured in the final configuration.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The hinge mechanism enables change of geometric parameters including the position and orientation of the closure relative to the opening. By adjusting the length and angle of the movable element parts, precise alignment can be achieved to ensure the closure moves into the correct closed position.

Inventive Principle:
Principle #35Parameter changes

AI summary

A hinge (10) has a first arm (14) pivotally mounted to a first mounting element (11) and a second arm (15) pivotally mounted to a second mounting element (12). The first and second arms (14, 15) intersect and are pivotally joined by a pivot (13). A first link (24) is pivotally connected to the first mounting element (11) and pivotally coupled to the second arm (15). A second link 21 is pivotally connected to the second mounting element (12) and pivotally coupled to the first arm (14). At least one of said first and second links (21, 24) is adjustable such as to adjust the position of the arm, to which the link is connected, with respect to a pivotal coupling of the mounting element to the arm. The first arm (14) is formed in two parts (31 and 32) which are pivotally coupled together whereby the angular position of one part (31) relative to the other part (32) can be altered and retained in an adjusted angular position by adjusting screws (44).
