Solution Overview

Problem

Setting up vehicle projectors and projector screens requires significant time and effort, and they are often difficult to position correctly on uneven surfaces, while the compact size of these systems can limit the optical path and projected image size.

Innovation Solution

An entertainment apparatus is fixed to a shuttle that extends from a vehicle tunnel, with a rotating platform for the projector and a mirror to extend the optical path, allowing quick deployment and protection from environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entertainment apparatus is stored within a sealed tunnel, then the electronic components are protected from environmental conditions, but the setup time and manual adjustment effort increase

Engineering Contradiction:
Improveprotection from environmental conditionsVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The projector and projector screen are pre-positioned and pre-adjusted within the sealed tunnel before deployment. The rotating platform is pre-configured to automatically orient the projector at the correct angle when deployed, eliminating the need for manual setup and adjustment after exiting the tunnel.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system performs self-adjustment through the rotating platform mechanism that automatically orients the projector at the correct angle relative to the projector screen upon deployment. The sealed tunnel environment maintains optimal conditions without requiring external intervention for protection.

Inventive Principle:
Principle #25Self-service

2Length of stationary object

If the projector is positioned to project light away from the projector screen, then the optical path can be extended using a mirror, but the device complexity increases

Engineering Contradiction:
Improveoptical path lengthVSAvoiddevice complexity
Core Design Contradiction:
Length of stationary objectVSDevice complexity

Solution Approach 1:

The optical path is extended by changing the spatial dimension through which light travels. Instead of projecting directly forward, the projector is oriented at an angle and uses a mirror to redirect light along an extended path that wraps around the device structure, effectively increasing optical path length without increasing the physical footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

A mirror is introduced as an intermediary element to redirect light from the projector to the projector screen. This allows the optical path to be extended while keeping the physical distance between projector and screen relatively short, resolving the contradiction between optical path length and device compactness.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If the projector is fixed in a compact configuration, then the device size is reduced, but the projected image size decreases

Engineering Contradiction:
Improvedevice sizeVSAvoidprojected image size
Core Design Contradiction:
Volume of moving objectVSArea of stationary object

Solution Approach 1:

The optical path is routed through three-dimensional space using angular projection and mirror reflection rather than a straight line. This allows the light to travel a longer effective distance within a compact physical envelope, maintaining large image size while keeping the device footprint small.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The projector is pre-positioned and pre-adjusted within the sealed tunnel before deployment. The rotating platform is pre-configured to automatically orient the projector at the correct angle when deployed, eliminating the need for manual setup and adjustment after exiting the tunnel.

Inventive Principle:
Principle #10Preliminary action

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 solution enables rapid setup and protection of entertainment components, maintaining image size without the need for manual adjustments, even in harsh environments.

Implementation Method 1

The projector can project light towards or onto the mirror of the entertainment apparatus. The mirror can reflect the light from the projector back towards the projector screen. This can extend the length of the optical path of light between the lens of the projector and the projector screen.
