Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection apparatuses lack effective methods to detect housing deterioration and cracks, especially in ceiling-suspended, wall-hung, and board-stand integrated states, which can lead to operational issues and safety concerns.
Innovation Solution
Incorporating a processor and an acceleration sensor to detect inclination changes, comparing initial and current detection values, and triggering warnings or shutting down the apparatus when threshold values are exceeded, thereby monitoring and preventing further use in case of deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an acceleration sensor is used to detect housing deterioration, then detection capability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical inspection methods with an acceleration sensor that uses inertial measurement to detect housing deterioration. The sensor captures acceleration data along multiple axes, and through signal processing, determines whether the housing has deteriorated without requiring mechanical disassembly or complex inspection equipment.
2Reliability
If continuous monitoring is performed to detect housing deterioration, then reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring where the acceleration sensor captures data at specific intervals or under specific conditions (such as during device operation or at scheduled times). The processor analyzes the accumulated data to determine housing deterioration, enabling reliable detection while minimizing continuous energy consumption by activating the sensor and processor only when needed.

AI summary
The present invention aims to make it possible to detect deterioration of a housing of a projection apparatus and to notify a user of the deterioration of the housing. A projection apparatus includes at least one processor and an acceleration sensor which detects an inclination of the projection apparatus, in which the processor performs the processes of acquiring a difference between i) a first detection value which is detected by the acceleration sensor in a case where the projection apparatus is installed on an installation surface and ii) a second value which is detected by the acceleration sensor at a time which comes after the installation of the projection apparatus with the projection apparatus on the installation surface, and in a case where the difference becomes more than a threshold value, controlling to notify a warning at a predetermined timing by functioning as a notification unit or to stop functions of the projection apparatus.
