Solution Overview

Problem

Existing vehicle window shades do not conveniently and stably attach to vehicle windows, failing to adapt to the entire shape of the window and provide flexible sunlight blocking and temperature control.

Innovation Solution

A stretchable window shade with a panel and frame made of elastic materials, incorporating a hook and loop structure and magnetic positioning tabs to securely attach to a vehicle door frame, allowing for adjustable coverage and flexibility to fit various window shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple rectangular fabric sheet is used for the window shade, then the device complexity is reduced, but the adaptability to different window shapes and sizes deteriorates

Engineering Contradiction:
Improvestructure complexityVSAvoidadaptability to window shape
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The window shade incorporates elastic/stretchable material that can dynamically adjust its shape and size to fit different window geometries. The material's inherent elasticity allows it to stretch and conform to various window shapes while maintaining structural integrity, eliminating the need for multiple rigid size variants.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes materials with variable physical properties, specifically elastic materials that can change their dimensional parameters (length, width, shape) in response to stretching forces. This parameter change capability enables a single shade design to adapt to multiple window configurations without increasing overall device complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If simple attachment mechanisms are used, then the ease of operation is improved, but the stability and secure attachment deteriorates

Engineering Contradiction:
Improveattachment convenienceVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces traditional mechanical attachment systems (screws, clips, adhesives) with magnetic attachment mechanisms. Magnets provide secure holding force through magnetic attraction while allowing for easy attachment and detachment without tools, combining operational ease with reliable stability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic attachment system utilizes adjustable magnetic field strength to provide adequate holding force for stable attachment while maintaining ease of operation. The magnetic force can be engineered to provide sufficient attraction for security yet allow simple removal when needed, balancing both requirements.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If permanent window tinting is applied, then the light blocking effectiveness is improved, but the ease of repair and removal deteriorates

Engineering Contradiction:
Improvelight blocking capabilityVSAvoidremovability
Core Design Contradiction:
Illumination intensityVSEase of repair

Solution Approach 1:

The window shade is designed as a separate, removable component rather than being permanently integrated into the window structure. This segmentation allows the light-blocking function to be provided by a detachable shade that can be easily removed or replaced, unlike permanent tinting that requires complex removal processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The magnetic attachment system acts as an intermediary between the window shade and the vehicle window frame, providing a reversible connection that maintains light blocking effectiveness while enabling easy removal and reattachment, unlike permanent chemical bonding methods.

Inventive Principle:
Principle #24Intermediary (Mediator)
