Solution Overview

Problem

Existing corner bearings for windows and balcony doors are complex to adjust, requiring both horizontal and vertical tool application, often lacking space for horizontal tool attachment, and do not allow for transverse movement of the wing relative to its plane, making adjustments cumbersome and requiring alternative tightening points.

Innovation Solution

The second adjusting means is designed transversely to the wing's plane, allowing vertical tool application for easy height and frame alignment adjustments, with features like horizontal guides, inclined guide ramps, and conical sections to simplify and stabilize the adjustment process, and provide easy accessibility and low component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the second adjusting means is arranged horizontally like the first adjusting means, then both adjusting screws are accessible from the same side, but the adjustment becomes very complex and requires both horizontal and vertical tool application which is not always possible

Engineering Contradiction:
Improveadjustment accessibilityVSAvoidadjustment complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The second adjusting means is oriented transversely to the plane of the wing, perpendicular to the first adjusting means. This spatial arrangement allows both adjusting screws to be accessed from the same side (vertically) without requiring horizontal tool application, thereby simplifying the adjustment operation while maintaining accessibility

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the corner bearing allows transverse movement of the wing, then the tightening can be adjusted directly at the corner bearing, but the structure becomes more complex

Engineering Contradiction:
Improvetightening adjustment locationVSAvoidcorner bearing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The support part and base part are connected via a horizontal guide that combines the transverse movement function with the existing adjusting mechanism. The guide ramp and guide part integration merges multiple functions (movement guidance, adjustment transmission, structural support) into a unified structure, avoiding additional complex components

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The corner bearing has a wing-side fitting portion (6) is provided with a handle assembly (7) that is connected to a base portion (9) for connection with a wing (2) having a support portion (10). An actuating unit (12) adjusts the height of the wing. An actuator unit (13) adjusts the support portion relative to the base portion through adjusting screws (15,16), which is formed transversely to the plane of the wing, such that parallel axes of rotation of actuator units (12,13) are accessible to rotation from the same side of wing-side fitting portion.
