Solution Overview

Problem

Electronic apparatuses that receive HDR content through wireless communication often cannot display it properly due to unsupported formats, leading to image distortion.

Innovation Solution

An electronic apparatus with a connector for wired connection and a communicator for wireless communication, featuring an image processor that converts HDR content into a compatible format (such as SDR or LDR) for display on connected devices, ensuring synchronized and distortion-free image display across various external apparatuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If HDR content is transmitted through wireless communication to external apparatus, then image quality and brightness expression are improved, but image distortion occurs when the external apparatus does not support HDR format

Engineering Contradiction:

Improvebrightness expressionVSAvoidimage display compatibility

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The image processor dynamically changes the format parameter of the image signal from HDR to SDR/LDR based on the capabilities of the connected external apparatus. When a wireless connection is detected, the system identifies whether the external apparatus supports HDR format and converts the signal format accordingly, allowing high brightness expression when supported while ensuring compatibility when it is not.

2Adaptability or versatility

If image signal format is converted from HDR to SDR/LDR for wireless transmission, then compatibility with external apparatus is improved, but image quality and contrast expression are degraded

Engineering Contradiction:

Improveformat compatibilityVSAvoidcontrast expression

Core Design Contradiction:

Adaptability or versatilityVSIllumination intensity

Solution Approach 1:

The system dynamically adjusts the image signal format based on real-time detection of the external apparatus's capabilities. The image processor can switch between HDR and SDR/LDR formats as needed, maintaining optimal image quality when the apparatus supports HDR while ensuring broad compatibility when it does not. This dynamic adaptation resolves the contradiction between format compatibility and image quality.

3Adaptability or versatility

If the electronic apparatus simultaneously supports both wired and wireless connections, then versatility and ease of operation are improved, but device complexity increases

Engineering Contradiction:

Improveconnection versatilityVSAvoidprocessor configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The image processor is designed with multi-functionality to handle both wired (HDMI) and wireless (Wi-Fi, Bluetooth) connections through a single processing unit. The processor can identify the connection type and automatically adjust the image signal format accordingly, eliminating the need for separate processing paths and reducing overall system complexity while maintaining connection versatility.
