Solution Overview
Problem
Conventional suspending-type lighting devices do not adequately incorporate projectors, and existing techniques fail to consider the optical characteristics and performance of projectors integrated into these devices, lacking usability for video-image projection functions.
Innovation Solution
A lighting device with a projection type video image display unit that is suspended from a ceiling at multiple points, allowing for horizontal adjustment to ensure proper alignment and image projection quality, utilizing a horizontality adjustment mechanism involving adjustable wires and interactive functions for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projector is integrally incorporated into a suspending-type lighting device, then the device gains video-image projection function, but the alignment and horizontality of the projection become difficult to control
Solution Approach 1:
The projection unit displays guidance images showing the desired horizontal position and alignment state. The system provides visual feedback to users, enabling them to adjust the suspending structure until the projection achieves proper horizontality and alignment with the projection surface.
Solution Approach 2:
A guidance image displayed by the projection unit serves as an intermediary between the device's internal state and the user's adjustment actions. This visual mediator translates complex alignment requirements into simple, intuitive visual cues that guide user operation.
2Adaptability or versatility
If a projector is integrally incorporated into a suspending-type lighting device, then the device gains video-image projection function, but the projection quality and image clarity deteriorate due to alignment errors
Solution Approach 1:
The projection unit provides real-time visual feedback through guidance images that indicate the current alignment status and desired adjustment direction. This feedback mechanism enables users to achieve precise projection alignment and horizontality, ensuring high image quality and clarity.
Solution Approach 2:
The system performs preliminary alignment by displaying guidance images before the actual projection content is presented. This preliminary action allows users to correct alignment issues in advance, preventing degradation of projection quality.
3Stability of the object's composition
If the lighting device is suspended at multiple points for stability, then the structural stability improves, but the complexity of the suspending structure increases
Solution Approach 1:
The projection unit serves multiple functions: it provides video-image projection, displays guidance images for alignment, and acts as a visual indicator for horizontality adjustment. This multi-functionality reduces the need for separate alignment indicators or adjustment mechanisms, simplifying the overall suspending structure while maintaining stability.
4Ease of operation
If conventional lighting devices are used without integrated projector technology, then the device simplicity is maintained, but the usability for video-image projection purposes is lost
Solution Approach 1:
The patent merges the lighting function and video-image projection function into a single integrally incorporated device. The projection unit is combined with the suspending-type lighting device, creating a unified system that provides both illumination and visual content display capabilities, thereby improving usability without requiring separate devices.
