Remote Controller Wireless Screen Projection Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless screen projection systems, such as meeting tablets and wireless screen projectors, have high manufacturing costs and low performance-cost ratios, requiring both devices to function together for effective multimedia transmission.
Innovation Solution
A remote controller with a first interface connected to a screen projection device and a first wireless portion for connecting to a display device, allowing data to be wirelessly transmitted from the screen projection device to the display device, thereby reducing costs and improving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a meeting tablet and wireless screen delivering device are used together for wireless screen projection, then the screen projection function is achieved, but the manufacturing cost and device price are high
Solution Approach 1:
The patent extracts the core wireless transmission functionality from the complex meeting tablet system and relocates it to a simple remote controller. The remote controller contains only the essential wireless communication module needed for screen projection, while the terminal device handles data processing and the display device handles rendering, thereby reducing manufacturing costs.
Solution Approach 2:
The remote controller serves as an intermediary device that bridges the terminal device and display device for wireless screen projection. It receives data from the terminal device via wired connection and transmits it wirelessly to the display device, eliminating the need for expensive dedicated projection devices.
2Reliability
If meeting tablet and wireless screen projector are used together, then wireless screen projection is implemented, but the device complexity increases
Solution Approach 1:
The patent extracts the wireless transmission function from the terminal device or display device and places it in the remote controller, which is already a familiar device to users. This avoids the need for users to adapt to new complex devices while achieving the same projection functionality.
Solution Approach 2:
The remote controller is designed with multi-functionality, serving both as a traditional remote control and as a wireless transmission device for screen projection. This universal approach eliminates the need for separate dedicated projection devices, reducing overall system complexity.
3Reliability
If traditional wireless screen projection systems are used, then screen projection is achieved, but the performance-cost ratio is low
Solution Approach 1:
The patent merges the wireless transmission function with the existing remote controller, which is already present in most display devices. This combination leverages existing infrastructure and avoids the need for additional expensive dedicated projection equipment, thereby improving the performance-cost ratio.
Solution Approach 2:
The remote controller uses a cost-effective wired connection (USB interface) between the terminal device and remote controller, rather than expensive wireless connections on both ends. This approach prioritizes cost-effectiveness while maintaining functional reliability.
