Solution Overview

Problem

The quality of projected content from electronic devices is affected by the surface onto which it is projected, as different surfaces require distinct projection parameters that existing technologies fail to adapt effectively.

Innovation Solution

An electronic device method and system that utilizes different projection parameters based on specific projection-mode triggers, allowing for optimal content display on various surfaces by adjusting brightness, color, size, and location of the content, and determining the appropriate projection parameters for the surface type, such as HUD cradles or tilted surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single set of projection parameters is used for all surfaces, then the device complexity is reduced, but the projection quality on different surfaces deteriorates

Engineering Contradiction:
Improveprojection parameter managementVSAvoidprojection quality
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent implements dynamic projection parameters that automatically adjust based on the detected surface type. The system transitions from static, fixed parameters to dynamic, adaptive parameters that change in real-time according to surface characteristics such as reflectivity, texture, and angle, thereby maintaining high projection quality across diverse surfaces without increasing device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes projection parameters (such as brightness, contrast, focal length) based on detected surface properties. By modifying these parameters dynamically according to surface type classification, the system achieves optimal projection quality on different surfaces while maintaining a simple device architecture that automatically adapts rather than requiring complex manual configuration.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If projection parameters are manually adjusted for each surface type, then projection quality improves, but the ease of operation deteriorates

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent enables the projection system to automatically detect surface type and adjust parameters without user intervention. The device performs self-diagnosis of surface characteristics and self-adjustment of projection parameters, eliminating the need for manual operation while maintaining optimal projection quality across different surface types.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements a feedback loop where surface detection information is continuously monitored and used to automatically adjust projection parameters. This closed-loop control ensures optimal projection quality is maintained adaptively without requiring manual user input or complex operational procedures.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If projection parameters are optimized for specific surfaces, then projection quality on those surfaces improves, but the adaptability to other surfaces deteriorates

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal projection system that can adapt to multiple surface types through automatic detection and parameter adjustment. Rather than requiring separate optimization for each surface type, the system implements a multi-functional capability that handles diverse surfaces (glass, metal, plastic, textured surfaces) with a single adaptive mechanism, achieving both specific surface optimization and broad adaptability.

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

Solution Approach 2:

The system transitions from static, surface-specific parameter sets to dynamic, universally applicable parameters that automatically adapt to any surface type. This dynamic approach allows the same projection system to optimize for different surfaces in real-time, achieving both specialized performance and broad versatility without compromising either.

Inventive Principle:
Principle #15Dynamics
