Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle customization methods, such as branding on surfaces like lavatories, are expensive, require special assembly line setups, and are not easily removable, leading to production delays and space constraints.

Innovation Solution

A projector system that projects images onto translucent displays made of materials like acrylic polymer and alumina trihydrate, controlled by a projector controller, allowing for customizable images without altering the vehicle's structure, and adjusting based on sensor inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If custom branding is applied to vehicle surfaces during assembly, then brand visibility and passenger comfort are improved, but production complexity and costs increase significantly

Engineering Contradiction:

Improvebrand customizationVSAvoidassembly line setup

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent uses projection technology to create visual copies of brand logos and images on translucent surfaces instead of physical customization. The projector system displays branded content on the baby-changing station surface, allowing brand visibility without modifying the actual vehicle structure or requiring special assembly line equipment.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The invention replaces mechanical customization methods (physical application of logos, decals, or painted surfaces) with an optical projection system. Instead of mechanically altering the vehicle interior surfaces during assembly, the system uses digital projection to display branded imagery, eliminating the need for specialized assembly line equipment and reducing production complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If permanent customization is applied to vehicle surfaces, then brand visibility is improved, but flexibility and resale value deteriorate

Engineering Contradiction:

Improvebrand visibilityVSAvoidcustomization removal

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The projection system provides dynamic branding capability where logos and images can be changed, updated, or removed at any time without physical modification to the vehicle. The branded content is displayed through projection rather than permanently applied, allowing complete flexibility for different brands, routes, or promotional campaigns while maintaining the original surface integrity.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If additional customization equipment is installed, then branding capability is improved, but available space and installation complexity worsen

Engineering Contradiction:

Improvesurface customizationVSAvoidequipment space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The projection system serves multiple functions within a compact form factor. The same projector unit can display brand logos, safety information, operational instructions, and promotional content on various translucent surfaces throughout the vehicle. This multi-functionality eliminates the need for separate equipment for different customization needs, maximizing the use of limited space in the vehicle interior.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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

Enables cost-effective, space-efficient customization of vehicle surfaces with seamless image projection, avoiding obstructions and allowing for dynamic image changes, enhancing passenger experience.

Implementation Method 1

a first image is projected onto a first translucent projection area of the baby-changing station. The baby-changing station includes a translucent projection area having a projection face and a display face, where the display face is an opposite side of the baby-changing station from the projection face

Methodology Applied

Scientific EffectLight transmission through translucent material: Refraction

AI summary

A method for operating a projector system, where the method is implemented by a projector controller. The method comprises: receiving a first signal from a first sensor; determining a first projection sequence to display in response to the first signal from the first sensor; determining a first translucent display and a corresponding first projector to display the first projection sequence; transmitting instructions to the first projector to project the first projection sequence onto the first translucent display; receiving a second signal from a second sensor; determining a second projection sequence to display in response to the second signal from the second sensor; determining a second translucent display and a corresponding second projector to display the second projection sequence; and transmitting instructions to the second projector to project the second projection sequence onto the second translucent display.
