Solution Overview

Problem

Existing window pane mounting systems are inefficient in terms of component design and assembly, requiring complex latching mechanisms and materials that are not easily adaptable for improved sealing and guidance.

Innovation Solution

A window mount system featuring a T-profiled carrier element with a cover connected via projections and depressions, forming a non-detachable connection using hook-shaped elements, and an overmoulding design that surrounds the support element for enhanced sealing and assembly ease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If complex latching mechanisms are used to connect the cover to the carrier element, then the connection strength is improved, but the device complexity and assembly effort increase

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The connection system is segmented into discrete components: carrier element with integrated connecting elements, cover with corresponding receptacles, and optional reinforcement elements. This segmentation allows for simplified assembly while maintaining connection strength through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting elements (protrusions) are pre-formed as integral parts of the carrier element during manufacturing. This preliminary action eliminates the need for complex assembly operations and reduces device complexity while ensuring strong connections when the cover is installed.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the sealing profile is separately accommodated in a groove, then the sealing function is improved, but the device complexity increases

Engineering Contradiction:
Improvesealing reliabilityVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The groove for accommodating the sealing profile is merged with the carrier element structure itself rather than being a separate component. This integration maintains reliable sealing functionality while reducing device complexity by eliminating additional sealing-specific structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carrier element serves multiple functions: it provides structural support, contains the groove for the sealing profile, and includes connecting elements for attaching the cover. This multi-functionality improves sealing reliability while avoiding the need for separate dedicated sealing components.

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

3Adaptability or versatility

If the carrier element is profiled as a T-shape with different leg lengths, then the adaptability for different window configurations is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveconfiguration adaptabilityVSAvoidprofile precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The carrier element employs asymmetric T-profile design with legs of different lengths to accommodate various window configurations and mounting positions. This asymmetry provides adaptability for different vehicle door designs while the profile is manufactured as a single extruded piece, keeping manufacturing precision requirements manageable through standard extrusion processes.

Inventive Principle:
Principle #4Asymmetry

AI summary

The disc has a wheel support which is attached to a fixed plate (1) and serves to guide the movable plate (8). A carrier element (3) is designed as a rail, and a connection plate (6) is fixed by which the disc is connected to the carrier element. One edge of the movable plate is accommodated with the sealing profile (7). The sealing profile is inserted into the groove formed in cover (5), by the carrier element. The cover is connected with the connection plate through the connecting elements (9).
