Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors face issues with normal operation failure in detecting and drawing control due to various causes such as environmental factors, user errors, and device malfunctions, making it difficult for remote support staff to diagnose the cause.
Innovation Solution
A system that includes a projector, a monitoring terminal, a cloud server, and an information processing device to acquire and display error information related to optical detection of indicators via a network, allowing remote support staff to diagnose and address issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projector performs detection and drawing control according to the position of an indicator, then the projector can respond to user input and perform display control, but the device may fail to operate normally due to various causes making it difficult to diagnose the cause when support staff are in a remote place
Solution Approach 1:
The patent introduces an intermediary system consisting of a communication unit and remote support terminal that mediates between the projector and support staff. The communication unit collects error information from the projector and transmits it to the remote support terminal, enabling support staff to access error details without being physically present at the projector location. This intermediary system resolves the contradiction by providing error information availability while maintaining ease of operation for remote troubleshooting.
2Reliability
If the projector detects the position of an indicator optically, then the projector can perform display control based on position, but detection failures occur due to environmental factors, user errors, or device malfunctions
Solution Approach 1:
The patent implements preliminary action by having the communication unit automatically collect and transmit error information before support staff intervene. The system proactively gathers detection failure information and makes it available to remote support staff, enabling them to diagnose and resolve issues without needing to physically inspect the projector. This preliminary information collection improves detection reliability monitoring while avoiding the complexity of adding physical inspection procedures.
