Solution Overview

Problem

The existing methods for mounting side doors in vehicles are ergonomically challenging, prone to trim scratches, and require a long assembly time, with risks of quality issues and vibration damping problems.

Innovation Solution

A guiding device for the window comprising a slide guide with an inclined bottom and oblique walls, allowing the window to be mounted along a tertiary axis distinct from the primary axis, with flexible seals to dampen vibrations and reduce assembly complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the window is mounted using conventional slides and guide devices, then the window can be guided along the primary axis, but the assembly process requires long time and attention due to ergonomic constraints

Engineering Contradiction:
Improveassembly timeVSAvoidergonomics for operator
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces a tertiary axis (Y3) distinct from the primary axis (X1) along which the window is guided during assembly. This dimensional change allows the window to be mounted from a different direction, improving operator ergonomics and reducing assembly time by enabling more efficient access and positioning during the mounting process

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

2Manufacturing precision

If the window is guided along the primary axis perpendicular to the side door, then the window can be properly positioned, but the risk of trim scratches increases due to operator constraints

Engineering Contradiction:
Improvewindow positioning accuracyVSAvoidrisk of trim scratches
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a guide device comprising a support with an inclined bottom and oblique walls that act as an intermediary between the operator and the window. This intermediary structure guides the window along the tertiary axis, enabling precise positioning while protecting the trim from scratches by providing a controlled, protected path for window insertion

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If conventional slide guides are used without additional support structures, then the device complexity is low, but the ability to guide the window along a tertiary axis is insufficient

Engineering Contradiction:
Improveguidance capability along tertiary axisVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the support structure with the slide guide device, creating an integrated assembly where the support having an inclined bottom and oblique walls is combined with the slide guide. This merging provides enhanced guidance capability along the tertiary axis while minimizing additional complexity by consolidating functions into a single integrated device

Inventive Principle:
Principle #5Merging (Combining)
