Solution Overview

Problem

Existing mounting systems for interior panels in vehicles, such as screws or bolts, create unsightly blemishes and are vulnerable to tampering, and are difficult to detach during maintenance due to their size and shape, often requiring multiple people.

Innovation Solution

A self-locking mounting insert comprising a main body, a latching member, a backplate, and a spring, with a keyway and guide channel system that uses a magnetic latching mechanism to securely attach and detach panels, allowing for easy panel removal with a magnetic tool.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws or bolts are used to attach interior panels, then the panels can be securely fastened to walls and structures, but unsightly blemishes and inconsistencies appear on visible surfaces

Engineering Contradiction:
Improveattachment securityVSAvoidunsightly blemishes
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The fastening function is extracted from the visible panel surface and relocated to the mounting insert hidden behind the panel. The insert contains all fastening components (latching member, spring, guide channel) within its body, leaving only a clean flush surface visible on the panel.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The latching member is nested within the hollow body of the mounting insert, with the spring nested around the guide channel. This nested arrangement consolidates multiple components into a compact hidden structure that provides secure attachment without visible elements.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If traditional fasteners are used, then panels can be attached securely, but they are subject to tampering by passengers

Engineering Contradiction:
Improveattachment securityVSAvoidtampering vulnerability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The latching member is nested within the hollow body of the mounting insert, with the spring nested around the guide channel. This nested arrangement consolidates multiple components into a compact hidden structure that provides secure attachment without visible elements.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The guide channel acts as an intermediary mechanism that controls access to the retention cavity. The tab can only be removed by compressing the spring through the guide channel with a tool, preventing direct tampering while allowing controlled access for maintenance.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Area of stationary object

If interior panels are made large for coverage, then fewer panels are needed, but manipulating them for detachment becomes difficult and requires multiple people

Engineering Contradiction:
Improvepanel coverage areaVSAvoidpanel detachment ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The mounting system is segmented into discrete mounting inserts distributed across the panel structure. Each insert is an independent, small-scale mechanism that can be operated individually, allowing large panels to be detached in sections rather than as one heavy unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide channel acts as an intermediary mechanism that controls access to the retention cavity. The tab can only be removed by compressing the spring through the guide channel with a tool, preventing direct tampering while allowing controlled access for maintenance.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If a latching mechanism is added to enable easy detachment, then maintenance becomes easier, but the device complexity increases

Engineering Contradiction:
Improvepanel detachment easeVSAvoidmounting insert complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The latching function, spring mechanism, guide channel, and retention cavity are merged into a single integrated mounting insert component. This consolidation provides easy detachment functionality without proportionally increasing overall system complexity, as all elements work together within one compact unit.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spring automatically returns the latching member to its locked position after being compressed, providing self-service latching without requiring additional actuators or complex control mechanisms. The tool simply needs to compress the spring to release, and the spring handles the return motion automatically.

Inventive Principle:
Principle #25Self-service

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The self-locking mounting insert provides a secure and aesthetically pleasing attachment solution for interior panels, allowing for easy detachment during maintenance without the need for multiple people, while preventing tampering by passengers.

Implementation Method 1

The latching member may be magnetic. The latching member may be configured to be repelled by a magnetic tool and compress the spring in response to the magnetic tool being positioned proximate to the latching member.

Methodology Applied
Scientific EffectMagnetic repulsion: Ion Repulsion/Attraction

Implementation Method 2

The spring may be disposed between the backplate and the latching member to urge the latching member toward the keyway to at least partially occlude the keyway.

Methodology Applied
Scientific EffectElasticity: Elasticity

AI summary

A self-locking mounting insert (2) is provided for attaching a panel (34) to a vehicle structure. A tab (36) of the panel (34) may be inserted into a keyway (12) of the insert. The tab (36) may slide between a latched and unlatched position within the keyway (12). When in the latched position, a latching member (6) prevents the tab (36) from being removed from the keyway (12). By moving a magnet proximate to the latching member (6), the latching member (6) may be magnetically impelled to move to an unlatched position to permit the tab (36) to be removed from the keyway (12).
