Solution Overview
Problem
Large format display apparatuses face challenges in accurately sensing their state and surrounding conditions due to limitations in recognition range with a single sensor, making it difficult to effectively monitor and control the display systems.
Innovation Solution
A display apparatus equipped with multiple sensors, where each sensor is strategically positioned on different display modules and communicates through a Daisy Chain method, allowing for comprehensive sensing data collection and transmission to an external apparatus, enabling accurate monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If one sensor is used in the display apparatus, then the device complexity is reduced, but the measurement precision and recognition range are insufficient for large format displays
Solution Approach 1:
The display apparatus is divided into multiple display groups, each equipped with its own sensor. This segmentation allows each sensor to monitor a specific region, improving measurement precision for large format displays while distributing the sensing function across multiple independent units rather than requiring one complex omnidirectional sensor.
2Area of stationary object
If multiple sensors are deployed across different display modules, then the recognition range and sensing accuracy are improved, but the device complexity and data management burden increase
Solution Approach 1:
Multiple sensors across different display modules are merged into a unified sensing system managed by a single processor. The processor receives sensing data from all sensors, aggregates it, and performs centralized analysis, thereby expanding the recognition range while simplifying data management and reducing the complexity of coordinating multiple independent sensing systems.
Solution Approach 2:
The processor acts as an intermediary between multiple sensors and the control system. It receives raw sensing data from various sensors through the Daisy Chain method, processes and integrates this data, and then provides unified sensing results to external apparatuses, thereby managing the complexity of multiple sensors without requiring direct connections between all components.
3Reliability
If sensors are equipped on all display modules, then the comprehensive monitoring capability is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
Sensors are strategically positioned on specific display modules rather than uniformly distributed across all modules. The sensor placement is optimized based on the specific monitoring requirements of different regions, allowing comprehensive monitoring capability where needed while reducing unnecessary sensors in areas with lower monitoring demands, thereby balancing reliability with manufacturing cost and complexity.
