Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing frameless window systems for vehicles lack an efficient mechanism for adjusting the glass sealing in the Y direction, making it difficult to securely install and adjust windows.

Innovation Solution

An adjustable cursor assembly is designed for frameless vehicle windows, comprising a cursor body with a hook portion and an isolator with a living hinge, allowing for securement and adjustment of the window in various directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional fixed cursor assembly is used for frameless windows, then the structure is simple, but the glass sealing adjustment capability in the Y direction is insufficient

Engineering Contradiction:

Improveglass sealing adjustment capabilityVSAvoidcursor assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cursor assembly incorporates a dynamic adjustment mechanism that allows the cursor body to move relative to the isolator in the Y direction. This dynamic capability enables glass sealing adjustment while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and device complexity.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cursor assembly is divided into separate components including the cursor body, isolator, and adjustment mechanism. This segmentation allows each component to perform its specific function independently, enabling Y-direction adjustment capability without significantly increasing overall structural complexity.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the isolator is made fully movable to allow adjustment, then the installation flexibility is improved, but the stability and positioning precision deteriorate

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidpositioning precision

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The isolator is designed with selective mobility - it can move in the Y direction for adjustment purposes, but remains stable and fixed in other directions. This controlled dynamics approach provides both installation flexibility and positioning precision, resolving the contradiction between ease of operation and reliability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different portions of the isolator have different mobility characteristics. The portion interfacing with the cursor body allows Y-direction movement for adjustment, while other portions maintain fixed positioning to ensure stability. This local differentiation of quality resolves the contradiction between flexibility and precision.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If the cursor assembly allows free movement of components, then the ease of installation is improved, but the control over unwanted movement deteriorates

Engineering Contradiction:

Improveease of installationVSAvoidcontrol over unwanted movement

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The cursor assembly employs controlled dynamics where components can move freely in the Y direction during installation for ease of positioning, but are constrained in other directions to prevent unwanted movement. This selective freedom resolves the contradiction between ease of installation and stability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The isolator acts as an intermediary element between the cursor body and the glass, mediating the movement control. It allows necessary movement for installation while restraining unwanted movements, thus resolving the contradiction between operational ease and compositional stability.

Inventive Principle:

Principle #24Intermediary (Mediator)
