Solution Overview

Problem

Existing display apparatuses face issues with wireless communication stability due to signal attenuation caused by obstacles made of specific materials, leading to low speed and disconnection problems.

Innovation Solution

A display apparatus equipped with a processor that identifies the material of obstacles in its vicinity and adjusts the transmission signal strength for wireless communication based on the identified material, using information obtained from user input, images, or sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication is set based on standard measurement conditions, then communication setup is simple, but signal attenuation occurs when obstacles are present

Engineering Contradiction:
Improvewireless communication setupVSAvoidwireless communication stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system changes the transmission signal parameters (power level, frequency) based on the identified obstacle material properties. The processor adjusts communication parameters dynamically according to the dielectric constant and signal attenuation characteristics of detected materials like concrete, brick, or glass walls.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system implements feedback by detecting obstacle materials using sensors or images, processing this information to determine appropriate transmission parameters, and adjusting the wireless communication settings accordingly. This closed-loop approach ensures reliable communication despite varying environmental conditions.

Inventive Principle:
Principle #23Feedback

2Reliability

If transmission signal strength is increased to overcome obstacle attenuation, then communication reliability improves, but energy consumption increases

Engineering Contradiction:
Improvewireless communication stabilityVSAvoidtransmission energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts transmission signal parameters based on the identified obstacle characteristics. Instead of using maximum power always, the processor selects appropriate power levels and frequency parameters matched to the specific material and distance conditions, optimizing the balance between reliability and energy efficiency.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The transmission parameters are made dynamic rather than static. The system continuously monitors the environment, identifies obstacle materials, and adjusts transmission power and parameters in real-time based on current conditions, allowing the system to use minimal necessary energy while maintaining reliability.

Inventive Principle:
Principle #15Dynamics
