Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional methods for customizing vehicle start/stop buttons using stickers, decals, or magnets result in lightweight attachments that can cause permanent damage and detachment issues due to adhesives, leading to operational degradation and visual defects.

Innovation Solution

An over-mount structure with a cylindrical mounting body and removably coupled faceplate that creates a press-fit engagement with the start/stop button, allowing for customization without modifying the button and ensuring secure attachment and easy installation/removal, while using a coil structure to facilitate key fob communication with the immobilizer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adhesives are used to attach stickers or decals to the start/stop button, then customization appearance is achieved, but permanent damage and deformation occur to the button

Engineering Contradiction:

Improvecustomization appearanceVSAvoidpermanent damage and deformation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The mounting body serves as an intermediary component between the start/stop button and the faceplate. It features a first mounting portion that interfaces with the button's outer periphery and a second mounting portion that receives the faceplate, thereby mediating the attachment process without direct adhesive contact between the faceplate and button

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the chemical bonding mechanism (adhesives) with a mechanical interference fit system. The first mounting portion of the mounting body is press-fit onto the outer periphery of the start/stop button, creating a secure mechanical attachment that avoids the damaging effects of adhesive removal

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional lightweight structures are used for customization, then installation simplicity is maintained, but attachment reliability deteriorates due to weight limitations and adhesive failure

Engineering Contradiction:

Improveinstallation simplicityVSAvoidattachment reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The over-mount structure is segmented into three main components: the mounting body, the faceplate, and the start/stop button itself. This segmentation allows each component to be optimized independently - the mounting body provides structural support and secure attachment, while the faceplate provides customization, and the assembly can be easily installed and removed as a unit

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The over-mount structure employs composite construction with the mounting body and faceplate formed as integrated components. The mounting body includes a first mounting portion for button attachment and a second mounting portion for faceplate reception, creating a composite structure that combines structural integrity with customization capability

Inventive Principle:

Principle #40Composite materials

3Ease of manufacture

If adhesives are used for attachment, then initial bonding is achieved, but long-term durability deteriorates as adhesives wear away causing attachment failure

Engineering Contradiction:

Improveinitial bondingVSAvoidattachment durability

Core Design Contradiction:

Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mounting body is designed with a press-fit engagement that creates excessive interference between the first mounting portion and the button's outer periphery. This intentional over-engineering of the fit ensures long-term durability by creating a very secure mechanical attachment that resists wear and maintains reliability over time

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An over-mount structure for over-mounting a vehicle start/stop button that is mounted in a housing with a gap defined between an outer periphery of the start/stop button and an inner periphery of the housing. The over-mount structure includes a mounting body having a first, generally cylindrical, mounting portion having a wall thickness sized to be received within the gap and having an inner diameter sized to make a removable press-fit engagement with an outer diameter of the start/stop button. The mounting body also includes a second generally cylindrical mounting portion, integral with the first mounting portion and in opposing relation therewith. A faceplate is removably coupled to the second mounting portion to cover an end thereof.
