Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional light bulbs are used for illumination, then they provide simple lighting functionality, but they lack the ability to project customizable images
Solution Approach 1:
The light bulb is segmented into functional components: a standard illuminating circuit for light generation and interchangeable gobo inserts for image projection. Each gobo is a separate, removable component that can be individually selected and attached to the transparent housing, allowing image projection functionality to be added without redesigning the entire light bulb structure.
Solution Approach 2:
The light bulb achieves multi-functionality by combining a standard illuminating circuit with interchangeable gobo inserts. The same basic structure can project different images by simply changing the gobo insert, making the device universal for both simple illumination and customizable image projection without requiring multiple specialized devices.
2Adaptability or versatility
If multiple gobos are provided for different images, then image versatility is improved, but device complexity increases
Solution Approach 1:
Multiple gobos serve multiple functions: each gobo insert acts as both a light filter and an image projector. The same gobo insert can be used with different illuminating circuits, and different gobos can be interchanged on the same housing, reducing the need for completely separate projection devices for each image.
Solution Approach 2:
The gobo inserts are thin, flat copies of image patterns that can be easily replicated and interchanged. Instead of complex three-dimensional projection mechanisms, simple two-dimensional gobo templates are used, which can be manufactured as flat inserts that fit into the transparent housing, simplifying the overall device structure while enabling multiple image options.
3Illumination intensity
If a transparent housing is used to enclose the illuminating circuit, then light transmission is improved, but structural visibility increases
Solution Approach 1:
The housing uses a transparent shell or thin transparent material that allows maximum light transmission while maintaining structural integrity. The transparent housing acts as a thin film enclosure that protects the illuminating circuit and gobo inserts while being optically transparent, enabling the light to pass through effectively for image projection.
