Solution Overview

Problem

Existing vehicle seat covers provide minimal protection to vehicle doors and surrounding areas, leaving them vulnerable to damage.

Innovation Solution

A vehicle door guard that can be secured to a vehicle seat cover, utilizing fasteners and fastening strips to extend protection to vehicle doors and sides, with options for attachment to vehicle components like windows, handles, and headrests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a vehicle seat cover is used to protect the seat, then the seat is protected, but the door and surrounding areas remain vulnerable to damage

Engineering Contradiction:
Improveprotection coverageVSAvoidprotection area
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The protection system is divided into separate components: a seat cover for the seat and a door guard for the door. The door guard is a separate segment that can be independently attached to extend protection to areas not covered by the seat cover alone.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door guard is combined with the seat cover system through attachment mechanisms (fasteners, straps, clips) to create an integrated protection assembly that covers both the seat and door areas, providing comprehensive coverage against harmful factors.

Inventive Principle:
Principle #5Merging (Combining)

2Object-affected harmful factors

If a door guard is added to extend protection to the door, then protection coverage is improved, but device complexity increases

Engineering Contradiction:
Improveprotection coverageVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The door guard incorporates adjustable and removable fastening mechanisms that allow dynamic configuration. The protection system can be adapted to different door positions and vehicle configurations, providing flexibility without permanent complex installation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The door guard utilizes flexible cover portions that can conform to the door surface, providing effective protection with a simple, adaptable structure rather than rigid complex frameworks.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If fasteners and fastening strips are used to secure the door guard, then the door guard remains stable, but the installation and removal process becomes more time-consuming

Engineering Contradiction:
Improveattachment stabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fastening system incorporates self-fastening mechanisms such as hook-and-loop fasteners, magnetic attachments, or snap-fit connections that automatically secure the door guard without requiring complex manual assembly or specialized tools, reducing installation time while maintaining stability.

Inventive Principle:
Principle #25Self-service
