Solution Overview

Problem

Existing adjustable carriages for separating elements, such as glass plates, face issues with undesirable displacement and torque during height adjustment, leading to potential material stress and detachment from rail elements under sudden forces.

Innovation Solution

A carriage design with a coupling part having inclined coupling surfaces allows height adjustment without displacing the carriage body, maintaining the carriage's position within the rail and avoiding torques, while a retraction device enables compact integration within the rail's cross-section for precise height and alignment adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the carriage body is moved vertically to adjust the height of the separating element, then the separating element can be adjusted in height, but the carriage body is also displaced horizontally in the direction of travel

Engineering Contradiction:
Improveheight adjustment precisionVSAvoidcarriage position stability
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The carriage is divided into two independent parts: a carriage body that remains stationary in the running rail, and a mounting body that carries the separating element. The mounting body can be adjusted vertically relative to the carriage body through the coupling part with inclined surfaces, while the carriage body itself does not move horizontally. This segmentation resolves the contradiction by allowing height adjustment without displacing the carriage body in the running direction.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If a buffer device is connected to the carriage body to form an end stop, then the separating element can be stopped at the desired position, but the buffer device must be displaced along the running rail when the carriage is adjusted

Engineering Contradiction:
Improveend stop position accuracyVSAvoidbuffer device adjustment complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The buffer device is connected to the mounting body rather than the carriage body, so it moves vertically with the mounting body when the separating element height is adjusted. The carriage body remains stationary and does not require readjustment of the buffer device position along the running rail. This resolves the contradiction by making the buffer device position independent of horizontal displacement.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If the carriage body is displaced vertically to adjust height, then the separating element height can be changed, but undesired torque acts on the separating element in the coupling area

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidmaterial stress in coupling area
Core Design Contradiction:
Manufacturing precisionVSStrength

Solution Approach 1:

The coupling part uses inclined surfaces that convert vertical movement of the mounting body into horizontal displacement of the coupling part itself, rather than directly displacing the carriage body vertically. This dimensional transformation allows height adjustment while maintaining the carriage body's position and avoiding torque in the coupling area between the separating element and carriage.

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

4Adaptability or versatility

If the carriage is designed to allow height adjustment, then the separating element can be positioned at selectable heights, but the carriage may become detached from the rail elements if forces act suddenly on the separating element

Engineering Contradiction:
Improveheight selection flexibilityVSAvoidcarriage-rail engagement stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The carriage body remains permanently engaged with the running rail through running wheels, while the mounting body carrying the separating element can be adjusted vertically. This segmentation ensures that the carriage body's connection to the rail is not compromised by height adjustment movements, maintaining reliable engagement even under sudden forces.

Inventive Principle:
Principle #1Segmentation

5Manufacturing precision

If the upper end of the separating element protrudes into the cross section of the running rail, then the separating element can be adjusted in height, but the transition area between the running rail and separating element requires additional covering elements

Engineering Contradiction:
Improveheight adjustment rangeVSAvoidcover profile requirements
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Instead of the carriage body protruding into the running rail cross-section, the solution inverts the arrangement by keeping the carriage body within the rail and allowing the mounting body with the separating element to extend outward. This inversion eliminates the need for additional cover profiles to mask the transition area, as the separating element's upper end does not intrude into the rail's cross-sectional space.

Inventive Principle:
Principle #13The other way round (Inversion)
