Smart Glasses Background Projection Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional projectors are bulky, complex to connect, and inconvenient to use when users need to perform other tasks while projecting content, as they require stopping the projection to do so.
Innovation Solution
A terminal with an intelligent operation module that processes both projection and display video signals simultaneously, allowing background projection without interrupting user operations, using a video processing module to handle these signals and transmit them to projection and display modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional projectors are used for projection, then projection performance is superior, but the device volume is large and not suitable to carry
Solution Approach 1:
The patent merges the projector functionality into a wearable device (smart glasses), combining the projection module with the display device. This integration allows the projection function to be embedded within a compact form factor, resolving the contradiction between maintaining projection performance and reducing device volume.
Solution Approach 2:
The projection module is nested within the smart glasses structure, with the projection lens and light source integrated into the existing device architecture. This nesting approach enables the projector functionality to be contained within a small, wearable form factor while maintaining operational effectiveness.
2Reliability
If traditional projectors are used for projection, then projection quality is high, but the connection complexity increases
Solution Approach 1:
The patent combines the projection functionality directly into the smart glasses, eliminating the need for separate projection devices and complex connection setups. The integrated design allows users to project content directly from the wearable device without requiring additional equipment or complicated wiring.
Solution Approach 2:
The patent extracts the projection functionality from traditional standalone projectors and integrates it into the smart glasses platform. This extraction and reintegration simplifies the overall system by removing the need for external projection equipment and reducing connection complexity.
3Adaptability or versatility
If projection is performed using traditional methods, then projection function is dedicated, but the user must terminate projection to perform other operations
Solution Approach 1:
The smart glasses device performs multiple functions including display, projection, and communication operations simultaneously. The device can project content while the user continues to interact with the device through touch or voice commands, eliminating the need to terminate projection for other operations.
Solution Approach 2:
The patent enables continuous projection operation while the user performs other tasks. The projection function runs continuously in the background while the user can switch between different operations without interrupting the projection, maintaining the useful action of projection throughout.
4Adaptability or versatility
If the user wants to view documents while projecting video, then multitasking capability is needed, but traditional projection requires stopping projection first
Solution Approach 1:
The smart glasses enable simultaneous projection and document viewing capabilities. The user can project video content while accessing and viewing documents through the device's display or by switching between applications without stopping the projection, enabling true multitasking.
Solution Approach 2:
The projection function continues to operate continuously while the user switches between different tasks such as viewing documents, making calls, or controlling playback. This maintains the projection useful action without interruption and eliminates task switching delays.
