Hinge-Mounted Accessory Sleeve with Non-Scratch Lining

Solution Overview

Problem

Existing motor vehicle accessories that mount on door hinges tend to wobble or scratch the exterior paint, with existing secure solutions being large and cumbersome.

Innovation Solution

A motor vehicle accessory featuring an integral metal sleeve with a non-scratching non-metallic interior lining, which fits over the hinge and includes a coaxial metal post for secure mounting without damaging the hinge surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If accessories contain sleeves that mount over the hinge, then the accessory mounts securely to the hinge, but the accessory scratches the paint on the hinges

Engineering Contradiction:

Improvemounting securityVSAvoidpaint scratching

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary material (rubber, plastic, or other non-metallic material) that lines the interior surface of the metal sleeve. This intermediary layer acts as a mediator between the metal sleeve and the hinge paint, preventing direct contact and scratching while maintaining the secure mounting function of the sleeve.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs composite material construction by combining a metal sleeve (for structural strength and secure mounting) with a non-metallic lining material (for paint protection). This composite structure allows the accessory to simultaneously achieve both mounting security and paint surface protection.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If accessories contain a post that is inserted into the interior of the hinge, then the accessory mounts to the hinge, but the accessory wobbles

Engineering Contradiction:

Improvemounting simplicityVSAvoidmounting stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent uses the sleeve as an intermediary mounting structure that envelops the hinge rather than inserting a post into it. This sleeve-based intermediary approach provides broader contact area and more stable mounting compared to the post insertion method, eliminating the wobble issue while maintaining ease of installation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If an integral metal sleeve is used to mount over the hinge, then the accessory mounts securely, but the metal sleeve may scratch the exterior surface

Engineering Contradiction:

Improvemounting securityVSAvoidexterior surface scratching
