Solution Overview

Problem

Existing door hinges require complex and labor-intensive processes for lateral adjustment of the sash relative to the frame, often necessitating detachment from the sash profile and reattachment, which is cumbersome and inefficient.

Innovation Solution

A fitting part with a sash hinge and an adjusting unit that includes a base plate and actuating means, allowing for relative movement and adjustment of the sash hinge without detaching it from the sash profile, using a screw connection and stop surface for precise alignment and fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the sash hinge is firmly connected to the sash profile using a non-positive arrangement (screw connection), then the sash hinge can be adjusted laterally without detaching it, but the connection strength and stability are reduced

Engineering Contradiction:
Improveease of adjustmentVSAvoidconnection strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent applies the dynamics principle by transitioning from a static, fixed hinge connection to a dynamic, adjustable connection system. The base plate with recess and protrusion features enables the hinge to be positioned and secured at multiple locations along the sash profile, allowing lateral adjustment while maintaining firm connection through selective engagement of the protrusion with different recess positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies segmentation by dividing the connection system into distinct components: the base plate with multiple recesses, the protrusion feature, and the screw connection mechanism. This segmentation allows the hinge to be adjusted to different positions by engaging the protrusion with different recesses, enabling lateral adjustment while maintaining connection strength through the distributed recess positions.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the sash hinge is detachably connected to the sash profile, then lateral adjustment is possible, but the adjustment process becomes complex and labor-intensive requiring detachment and reattachment

Engineering Contradiction:
ImproveadjustabilityVSAvoidadjustment process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-positioning multiple recesses at predetermined locations on the base plate. These recesses are prepared in advance at specific positions to accommodate the protrusion feature, enabling the hinge to be adjusted to different lateral positions without requiring complex detachment and reattachment procedures. The recesses are pre-configured to guide the adjustment process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism - the base plate with recesses and protrusions - that mediates between the hinge and the sash profile. This intermediary structure enables lateral adjustment by providing discrete positioning points (recesses) that engage with the protrusion, simplifying the adjustment process while maintaining firm connection, eliminating the need for complete detachment and reattachment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the base plate is firmly fixed to the sash profile, then connection stability is improved, but lateral adjustment of the sash hinge becomes impossible

Engineering Contradiction:
Improveconnection stabilityVSAvoidlateral adjustability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent resolves this contradiction by creating a dynamic connection system where the base plate remains firmly fixed to the sash profile through screw connections, while the hinge can be adjusted laterally by repositioning the protrusion into different pre-configured recesses on the base plate. This maintains connection stability while enabling adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the connection system into the firmly fixed base plate (providing stability) and the adjustable hinge component (providing adaptability). The base plate contains multiple recesses at different positions, allowing the hinge to be secured at various lateral locations while the base plate itself remains stably fixed to the sash profile, thus achieving both stability and adjustability simultaneously.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables simple and efficient lateral adjustment of the sash in the assembled state without loosening the base plate's non-positive arrangement on the wing profile, significantly reducing the effort required for side adjustment and allowing for precise positioning.

Implementation Method 1

The adjusting means (10) can be moved relative to the base plate (8) by actuating an actuating means, in particular an adjusting screw (9)

Methodology Applied
Scientific EffectScrew mechanism: Screw

Implementation Method 2

The adjusting means (10) can abut against a stop surface (11) of the holder (7) and/or be firmly connected to the sash hinge (4) when inserted into the holder (7)

Methodology Applied
Scientific EffectMechanical contact and force: Mechanical Force

Implementation Method 3

When the fitting part is installed, the base plate is firmly connected to the sash or the sash profile, in particular in a force-fitting manner, preferably by a screw connection

Methodology Applied
Scientific EffectScrew connection: Screw
