Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses require manual selection of signal input interfaces when multiple sources are active, leading to inconvenient use and poor user experience.
Innovation Solution
A signal source detection and selection system comprising an input interface scanner, interface selector, signal processor, and output terminal that automatically scans and prioritizes signal input interfaces based on a priority table, with optional user-adjustable priorities and usage statistics for self-learning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal input interfaces are provided in a conventional display apparatus, then the adaptability and versatility of the apparatus is improved, but the ease of operation deteriorates because manual selection is required when multiple sources are active
Solution Approach 1:
The display apparatus automatically detects and selects signal sources without user intervention. The system monitors multiple input interfaces and autonomously determines which signal source to activate, making the apparatus serve itself rather than requiring manual user selection.
Solution Approach 2:
The system pre-configures priority tables for different signal input interfaces before actual signal reception. When multiple sources are detected, the pre-established priority ranking automatically determines the selected source, eliminating the need for real-time manual selection.
2Ease of operation
If automatic signal source selection is implemented, then the ease of operation is improved, but the device complexity increases due to additional detection and selection mechanisms
Solution Approach 1:
The signal processing unit performs multiple functions: it processes the actual signal content, detects the presence of signals at input interfaces, and determines priority based on pre-configured tables. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The patent combines the signal processing function with the signal source detection and selection functions into an integrated system. The same processing unit that handles signal content also monitors input interfaces and determines source priority, merging multiple functions into a single component.
