Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector is mounted to a lighting socket for home use, then the projector can function as both lighting and projection equipment, but it becomes difficult to effectively switch between and utilize both functions
Solution Approach 1:
The projector automatically determines whether to perform projection or illumination based on the received image signal characteristics. When the image signal indicates projection content (such as slides, videos, or text), the projector activates the projection function. When the image signal indicates illumination needs (such as dark scenes or low-light conditions), the projector switches to illumination mode. This self-service approach eliminates the need for manual switching and enables effective utilization of both functions.
Solution Approach 2:
The projector dynamically adjusts operational parameters based on the received image signal. The control unit analyzes the image signal to determine the appropriate mode (projection or illumination) and adjusts the light source intensity, diffusion degree, and optical path configuration accordingly. This parameter change approach allows seamless transition between functions and effective utilization of the projector's dual capabilities.
2Adaptability or versatility
If the projector is used in meeting rooms with dedicated sockets, then the projecting function can be utilized, but the illuminating function cannot be effectively used in home settings
Solution Approach 1:
The projector is designed with universal functionality to perform both projection and illumination tasks. By analyzing the received image signal characteristics, the projector automatically determines the appropriate function to perform. This multi-functionality design enables the projector to be effectively used in various settings including homes, where it can provide both lighting and projection services, thereby increasing overall productivity and utility.
3Measurement precision
If the diffusion degree is adjusted for clear projection, then the projection quality improves, but the illumination coverage and softness deteriorate
Solution Approach 1:
The projector dynamically adjusts the diffusion degree based on the operational mode determined from the image signal. In projection mode, the diffusion degree is set to a lower level to ensure clear and sharp projected images. In illumination mode, the diffusion degree is increased to provide soft, widespread lighting coverage. This dynamic adjustment mechanism allows the projector to optimize both projection clarity and illumination quality according to the current operational requirements.
Solution Approach 2:
The control unit changes the diffusion parameter based on the determined operational mode. When projection is required, the diffusion degree parameter is adjusted to minimize light scattering for sharp images. When illumination is required, the diffusion degree parameter is adjusted to maximize light distribution and softness. This parameter change approach enables the projector to achieve optimal performance for both projection and illumination functions.

AI summary
A projector can be easily attached by mounting a connecting unit to a socket for illumination in an ordinary home. Since the projector includes a communication unit configured to receive an electronic mail, the projector updates an image signal and adjusts a diffusion degree of modulated light by a light-diffusion adjusting unit on the basis of contents of the mail received by the communication unit. Therefore, when a user desires to inform family members who will return home that the user suddenly has to go out, if the user transmits in advance, to the projector, a mail including a message for a family member who returns home, the family member who returns home turns on an illumination switch at the entrance, whereby the projector can start up, perform an illuminating function, and clearly project and display the message.
