Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent miniature projectors lack the ability to efficiently switch between multiple user equipment (UEs) for content projection, limiting their flexibility and application in multi-device scenarios.
Innovation Solution
A method and device for multi-source control of intelligent miniature projectors, which involves detecting active content projection on a second UE, sending a switching confirmation prompt, and after consent, stopping the current projection to respond to a projection request from a first UE, allowing flexible switching between multiple UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector establishes one-to-one connection with a single UE for content projection, then the connection stability and content sharing are reliable, but the flexibility and adaptability to multi-device scenarios are limited
Solution Approach 1:
The patent implements dynamic source switching capability that allows the projector to transition between different UEs based on real-time needs. The system maintains one-to-one connection stability while enabling flexible switching between multiple devices through a unified control interface, resolving the contradiction between connection reliability and multi-device adaptability
Solution Approach 2:
The patent creates a universal control mechanism that can manage multiple UEs through a single unified interface. The projector serves multiple functions: maintaining stable one-to-one connections while also supporting multi-device coordination through centralized control, thus achieving both connection reliability and multi-device versatility
2Productivity
If the projector sequentially switches between multiple video input units according to a predetermined rule, then the coordination of multiple UEs is managed, but the projection efficiency and response time are reduced
Solution Approach 1:
The patent implements preliminary buffering and pre-loading mechanisms for video content from multiple UEs. By preparing content in advance and maintaining buffer zones, the system enables rapid switching between sources without sequential processing delays, significantly improving projection efficiency while minimizing switching time loss
3Ease of operation
If the projector implements wireless connection based on various protocol standards, then the convenience and flexibility of connection are improved, but the coordination of multiple UEs becomes more complex
Solution Approach 1:
The patent introduces a unified control interface that acts as an intermediary between multiple UEs and the projector. This mediator manages wireless connections from various protocol standards, translating diverse connection requests into standardized control commands, thereby maintaining ease of wireless operation while simplifying multi-UE coordination

AI summary
Described are a method and device for multi-source control of an intelligent miniature projector. With the method, connection of intelligent miniature projector equipment with multiple UEs is established; after a projection request sent by a first UE is received, when it is detected that played content of a second UE is being projected, a switching confirmation prompt is sent to the second UE; and after the second UE's consent for switching is received, the current projection process is stopped, a response to the projection request of the first UE is made, and played content of the first UE is projected.
