Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current methods for representing a vehicle cabin layout on a presentation surface are time-consuming and costly, requiring manual measurement and application of markings for contours and volume elements, which can take several hours to days.
Innovation Solution
A system comprising projectors, a planar projection surface, and a control system that loads digital cabin layout data to project the layout on the surface at original scale, reducing the need for manual measurement and minimizing shadow casting by arranging projectors perpendicular to the aisle sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement and application of markings are used to represent cabin layout, then the layout can be accurately transferred to the presentation surface, but the process is time-consuming and costly
Solution Approach 1:
The patent replaces manual mechanical measurement and marking operations with an automated projection system. Projectors equipped with digital cabin layout data project the layout directly onto the presentation surface, eliminating the need for manual measurement tools and marking applications. This substitution of mechanical processes with optical projection technology resolves the contradiction by achieving both high precision and rapid execution.
Solution Approach 2:
The patent creates a digital copy of the cabin layout data and uses projectors to reproduce this layout visually on the presentation surface. Instead of physically measuring and marking each element, the system projects a scaled representation of the entire layout at once. This copying approach maintains measurement precision while dramatically reducing the time required for layout transfer.
2Ease of operation
If permanent markings are applied on the presentation surface to simplify layout application, then the layout transfer becomes easier, but the presentation surface requires more materials and cannot be reused flexibly
Solution Approach 1:
The patent transforms the static, permanent marking approach into a dynamic, reconfigurable projection system. The presentation surface remains blank and flexible, while the projection system can dynamically display different cabin layouts by loading different digital data. This allows the same surface to be reused for multiple layout configurations without permanent markings, resolving the contradiction between ease of operation and system complexity.
Solution Approach 2:
Instead of permanently marking the presentation surface, the system creates temporary visual copies of the cabin layout through projection. These projected images can be easily changed by updating the digital cabin layout data, allowing flexible reconfiguration without modifying the physical surface. This copying mechanism maintains ease of operation while avoiding the complexity of permanent markings.
3Area of stationary object
If projectors are positioned to illuminate the entire cabin layout, then complete coverage is achieved, but shadows are cast that obscure parts of the projected layout
Solution Approach 1:
The patent divides the projection system into multiple separate projectors, each responsible for illuminating a specific section of the cabin layout. By segmenting the projection task across multiple devices positioned at different locations, the system achieves complete area coverage while minimizing shadow interference in any single region. Each projector illuminates its designated zone without casting shadows that would obscure other areas.
Solution Approach 2:
The patent applies different projection characteristics to different areas of the presentation surface. Projectors are strategically positioned and configured to provide optimal illumination for their respective zones, with adjustments made to each projector's angle, intensity, and positioning. This localized optimization ensures complete coverage while minimizing shadow effects in each specific area, resolving the contradiction between area coverage and shadow interference.

Implementation Method 1
The plurality of projectors comprises at least one first group of vertical projectors which are arranged at a distance from one another along a first projector axis. The control system is configured to drive the plurality of projectors and to process cabin layout data loaded into the control system such that the layout of the vehicle cabin is projected on the planar projection surface on the original scale

AI summary
A system for representing a vehicle cabin layout on an original scale comprising a plurality of projectors, a planar projection surface and a control system. The layout is loaded as digital cabin layout data into the control system and the layout comprises a first cabin aisle section extending along a first aisle axis. The projectors comprise vertical projectors spaced along a first projector axis. The control system drives the vertical projectors and processes cabin layout data loaded into the control system to project at least one section of the cabin layout on the planar projection surface on the original scale. That section of the layout which is projected by the vertical projectors comprises the first aisle section, such that the first aisle axis runs with the first projector axis in a first aisle plane extending perpendicular to the planar projection surface.
