Solution Overview

Problem

Modern display screens consume high power and bandwidth when displaying high-resolution content, especially when viewed from a distance, as they often operate at fixed resolutions without adapting to the viewer's proximity, leading to inefficient energy and data usage.

Innovation Solution

A device that dynamically adjusts display resolution based on estimated viewer distance using sensors and circuitry, reducing resolution for farther viewers to conserve power and bandwidth while maintaining a satisfactory viewing experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If display resolution is increased to improve image quality, then viewing quality is improved, but power consumption increases

Engineering Contradiction:
Improveviewing qualityVSAvoidpower consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The display resolution is made dynamic rather than fixed. The system continuously monitors viewer distance using sensors (cameras, depth sensors, or infrared sensors) and automatically adjusts the display resolution in real-time based on the detected distance, optimizing the balance between viewing quality and power consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display resolution parameter is changed dynamically based on viewer distance. When the viewer is far away, the system reduces resolution to save power; when the viewer is close, the system increases resolution to maintain viewing quality. This parameter adjustment is continuously adapted to current viewing conditions.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If display resolution is increased to improve image quality, then viewing quality is improved, but bandwidth consumption increases

Engineering Contradiction:
Improveviewing qualityVSAvoidbandwidth consumption
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The bandwidth requirement becomes dynamic based on actual viewing conditions. By adjusting resolution according to viewer distance, the system reduces the amount of data that needs to be transmitted over the network when high resolution is not necessary, thereby reducing bandwidth consumption while maintaining quality when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The data transmission parameter (resolution) is adjusted based on viewer distance. When viewers are far away, lower resolution content is transmitted, reducing bandwidth usage. When viewers are close, higher resolution content is transmitted to maintain viewing quality, optimizing network resource utilization.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If fixed high resolution is used to ensure consistent quality, then viewing quality is maintained, but adaptability to different viewing distances is reduced

Engineering Contradiction:
Improveviewing qualityVSAvoidadaptability to viewing distance
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static fixed-resolution approach to a dynamic adaptive-resolution approach. Multiple sensors detect viewer position and distance in real-time, and the display resolution is continuously adjusted to match the current viewing conditions, providing optimal quality for each specific viewing scenario.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements a feedback loop where sensors continuously monitor viewer distance and provide this information to the display control system. Based on this feedback, the system automatically adjusts the display resolution to optimize viewing quality for the current distance, creating a closed-loop adaptive system.

Inventive Principle:
Principle #23Feedback
