Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stereoscopic projector systems face challenges in transmitting synchronization signals to shutter glasses due to projector installation conditions, limiting the flexibility of signal reception and complicating handling, especially when the output unit is separated from the projector body.
Innovation Solution
A projector with a built-in transmitting unit that adjusts and rotates to direct the synchronization signal appropriately based on the projector's installation conditions, including position and tilt, ensuring signal reception regardless of installation orientation, and eliminating the need for separate cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the output unit is separated from the projector main body and connected using a cable, then the synchronizing signal can be transmitted in an arbitrary direction, but the handling becomes complicated and the appearance after installation is degraded
Solution Approach 1:
The patent merges the transmitting unit into the projector main body, integrating the synchronizing signal transmission function directly into the projector housing. This eliminates the need for separate output units and connecting cables, simplifying handling while maintaining the ability to transmit signals in various directions through the adjustable transmitting unit.
Solution Approach 2:
The transmitting unit is designed with adjustability, allowing it to change its orientation and transmission direction dynamically. This dynamic capability enables the integrated transmitting unit to transmit synchronizing signals in arbitrary directions without requiring external cables or separate units, thus maintaining versatility while improving handling.
2Adaptability or versatility
If the output unit is separated from the projector main body and connected using a cable, then the synchronizing signal can be transmitted in an arbitrary direction, but the appearance after installation is degraded
Solution Approach 1:
By integrating the transmitting unit into the projector main body, the patent eliminates external cables and separate components that would mar the appearance. The unified design maintains a clean, streamlined appearance while the adjustable transmitting unit preserves the capability to transmit signals in various directions.
3Device complexity
If the transmitting unit is integrated into the projector, then the handling is simplified and appearance is improved, but the transmission direction of the synchronizing signal is limited by the projector installation condition
Solution Approach 1:
The transmitting unit incorporates adjustability mechanisms that allow it to be oriented in different directions. This dynamic capability enables the integrated unit to adapt to various projector installation conditions (desk mounting, ceiling mounting, etc.) and transmit synchronizing signals appropriately, maintaining versatility while keeping the design integrated and simple to handle.
Solution Approach 2:
The adjustable transmitting unit is designed to perform multiple functions across different installation scenarios. It can transmit synchronizing signals in various directions depending on how the projector is installed, making the integrated design universally applicable to different mounting conditions without requiring external components.

AI summary
A projector includes an image projection unit that projects an image for left eye and an image for right eye, and a transmitting unit that transmits a synchronizing signal for synchronization with switching between the image for left eye and the image for right eye. The transmitting unit is arranged to adjust a transmission direction of the synchronizing signal.
