Solution Overview

Problem

Existing three-dimensional displays are complex and expensive, requiring high resolution and processor computation power, making them unsuitable for some applications.

Innovation Solution

Integration of a mechanical indicator assembly with one or more displays, where the mechanical assembly provides three-dimensional structure and the displays enhance visibility with digital content, allowing for three-dimensional information display without complex systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If multi-component displays with multiple stacked display screens are used to display real depth, then three-dimensional depth perception is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvethree-dimensional depth perceptionVSAvoidsystem complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent merges a mechanical indicator assembly with a display screen into a single integrated instrument panel. The mechanical indicators (needles, pointers) are positioned directly on the display screen, eliminating the need for separate stacked display components. This integration achieves three-dimensional depth perception through the mechanical structure's physical presence while avoiding the complexity of multiple independent display systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The display screen serves multiple functions: it displays digital information and simultaneously serves as the background for mechanical indicators. The mechanical indicator assembly provides both traditional analog readings and structural depth cues. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining three-dimensional visualization capabilities.

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

2Shape

If multi-component displays with multiple stacked display screens are used to display real depth, then three-dimensional depth perception is improved, but manufacturing cost increases

Engineering Contradiction:
Improvethree-dimensional depth perceptionVSAvoidmanufacturing cost
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

By combining the mechanical indicator assembly with a single display screen rather than using multiple stacked display screens, the patent reduces the number of components that need to be manufactured and assembled. This integration simplifies the manufacturing process and reduces material costs while still achieving the desired three-dimensional depth perception effect.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If mechanical indicator assembly is integrated with display screens, then three-dimensional information display is achieved without complex systems, but visibility enhancement requires additional digital content layers

Engineering Contradiction:
Improvesystem complexityVSAvoidnumber of display layers
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The patent merges digital and mechanical display elements into a unified instrument panel. The mechanical indicators provide physical depth and three-dimensional structure, while digital content layers overlay additional information. This combination achieves comprehensive information display without requiring multiple separate physical display screens, thereby reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vehicle instrument panel includes a display system that integrates a mechanical indicator assembly in an overlapping manner with one or more displays (e.g., LCDs or OLEDs). An instrument panel may include a mechanical indicator assembly including a pointer configured to rotate about an axis and thereby define an area swept by the pointer, a transparent display, a housing configured to support the mechanical indicator assembly and the transparent display overlaying the mechanical indicator assembly, and a control system configured to display, on the transparent display, content including text and/or graphics.
