Solution Overview

Problem

Existing vehicle cockpit systems face challenges in effectively displaying information due to curved surfaces and require integrated management of digital cockpits with varying display types, especially when using projectors.

Innovation Solution

A cockpit system utilizing a projector, an operating system, a screen, and a housing to adjust the position of the screen, applying a gradation pattern between the image plane and light boundary to enhance image clarity on curved surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a projector is used to display information on curved vehicle surfaces, then display flexibility and adaptability are improved, but image clarity and quality deteriorate due to light scattering on curved surfaces

Engineering Contradiction:
Improvedisplay flexibilityVSAvoidimage clarity
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

A screen is introduced as an intermediary component between the projector and the curved vehicle surface. The screen receives the projected light and redistributes it to form a clear image on the curved surface, mediating between the projector's light output and the curved surface's light scattering properties.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

A housing structure is used to change the position and orientation of the screen locally, allowing the screen to be optimally positioned at different locations on the curved vehicle surface. This enables the system to adapt to various curved surface geometries while maintaining image quality through localized adjustments.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If the screen position is adjusted to optimize image display, then image quality is improved, but device complexity increases due to additional positioning mechanisms

Engineering Contradiction:
Improveimage qualityVSAvoidpositioning mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The housing is designed to be movable and adjustable, allowing the screen position to be dynamically changed to optimize image display quality. The housing can be repositioned along the curved surface to achieve the best viewing angles and image clarity for different display scenarios.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The housing serves multiple functions: it supports the screen, provides structural protection, enables position adjustment, and can be integrated into the vehicle's existing structure. This multi-functionality reduces the need for separate components and simplifies the overall system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If a gradation pattern is applied to reduce light boundary effects, then image clarity is improved, but manufacturing complexity increases due to additional processing steps

Engineering Contradiction:
Improveimage clarityVSAvoidmanufacturing process simplicity
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

A gradation pattern is applied to the screen or housing to gradually transition the light intensity or color at the boundaries of the projected image. This reduces the harsh light boundary effects and creates a smoother, more visually pleasing transition between the projected image and the surrounding area.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The gradation pattern is applied in advance during the manufacturing or setup process, before the projector is installed and operational. This preliminary application of the gradation pattern simplifies the overall installation process and ensures optimal image quality from the start without requiring additional complex processing steps during operation.

Inventive Principle:
Principle #10Preliminary action
