Solution Overview

Problem

Existing display devices require manual adjustment of brightness and other parameters, which is impractical for users in certain body states, such as sleepiness, necessitating an automatic system to adapt parameters based on user body states.

Innovation Solution

An automatic parameter adjustment system for display devices, comprising a body state detector and a controller that acquires and adjusts display parameters such as brightness, color temperature, and volume based on detected user body states, including cortisol levels, heart rate, and movement, to automatically adapt to user conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of display parameters is used, then the user can control the display settings, but the user cannot adjust parameters when in a sleepy state

Engineering Contradiction:

Improveparameter adjustmentVSAvoidadaptation to body state

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The display device automatically detects the user's body state through sensors (heart rate, temperature, movement) and autonomously adjusts display parameters without requiring manual user input. The system serves itself by using detected physiological data to control display settings, eliminating the need for manual operation when the user is sleepy or unable to interact.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors user body state parameters through sensors and uses this feedback to dynamically adjust display parameters. The detected physiological data (heart rate, temperature, movement) serves as feedback that triggers automatic parameter changes, creating a closed-loop control system that adapts to user needs in real-time.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If automatic parameter adjustment is implemented, then the display adapts to user body state, but the device complexity increases

Engineering Contradiction:

Improveadaptation to body stateVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller serves multiple functions: it controls display parameters, processes sensor data, determines body state, and manages automatic adjustment logic. By making the controller multi-functional, the patent avoids adding separate dedicated components for each function, thereby reducing overall system complexity while achieving automatic adaptation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the body state detection functionality and parameter adjustment control into a single integrated system. The controller merges data processing, state determination, and display control functions, eliminating the need for separate independent modules and reducing system complexity through functional consolidation.

Inventive Principle:

Principle #5Merging (Combining)
