Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless display systems require a separate processing device in the A/V receiving device to process sensing data, leading to increased costs and power consumption, as they cannot utilize the main processing unit in the A/V transmitting device.
Innovation Solution
A wireless display system where the A/V receiving device acquires sensing data and transmits it to the A/V transmitting device, which processes the data and sends a power-on signal back to the A/V receiving device, eliminating the need for a separate processing device in the A/V receiving device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate processing device is added to the A/V receiving device to process sensing data, then the sensing data can be processed locally, but the device complexity and cost increase
Solution Approach 1:
The patent merges the sensing data processing function into the A/V transmitting device's existing main processing unit. The A/V receiving device only acquires sensing data and transmits it to the A/V transmitting device, which then processes the sensing data along with A/V data using its existing processor. This eliminates the need for a separate processing device in the A/V receiving device while maintaining full sensing data processing capability.
Solution Approach 2:
The main processing unit in the A/V transmitting device is designed to handle multiple functions simultaneously - both A/V data processing and sensing data processing. This multi-functional approach allows the single processing unit to perform diverse tasks without requiring dedicated hardware for each function, thereby reducing overall device complexity.
2Ease of operation
If a separate processing device is added to the A/V receiving device, then sensing data can be processed independently, but the power consumption increases
Solution Approach 1:
The patent combines sensing data processing with the A/V transmitting device's existing operations. The A/V receiving device performs only lightweight sensing data acquisition and transmission, while the A/V transmitting device handles the computationally intensive processing tasks using its existing power supply infrastructure. This distribution of processing tasks reduces overall power consumption compared to having a full processing device in the A/V receiving device.
Solution Approach 2:
The A/V receiving device performs only the minimum necessary processing - acquiring and transmitting sensing data - while delegating the more demanding processing tasks to the A/V transmitting device. This partial processing approach at the receiving end significantly reduces its power requirements while still achieving the overall processing goal.
3Ease of manufacture
If BLE communication circuit is used for transmitting sensing data and power-on signal, then the cost is reduced, but the data transmission capacity is limited
Solution Approach 1:
The patent segments data transmission into two distinct channels: BLE communication for low-capacity control data (sensing data and power-on signals) and RF communication for high-capacity A/V data. This segmentation allows each communication system to be optimized for its specific purpose - BLE for cost-effective control signaling and RF for bandwidth-intensive media transmission - thereby achieving overall system efficiency.
Solution Approach 2:
The BLE communication circuit serves as an intermediary for control functions, handling sensing data and power-on signals that require low data capacity but frequent transmission. This intermediary role allows the main RF communication system to focus on high-capacity A/V data transmission without being burdened by control signaling overhead.
