Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional projector uses a static light source and fixed projection lens, then the structure is simple, but the lighting effects are monotonous and static
Solution Approach 1:
The patent applies the Dynamics principle by introducing a rotating refractive lens that can change its orientation and refractive properties dynamically. This rotating lens creates variable lighting effects by altering the light path and refraction patterns, transforming the static projection system into a dynamic one that produces colorful and changing visual effects without requiring complete structural redesign
Solution Approach 2:
The patent implements Parameter changes by varying the refractive index and orientation of the refractive lens through rotation. By changing the physical parameters of the optical system (lens rotation angle, refractive properties), the projector generates diverse lighting effects and color variations, enabling adaptability in lighting effects while maintaining a relatively compact structure
2Adaptability or versatility
If an indoor-outdoor projector needs to provide dynamic lighting variations, then the lighting effects are enhanced, but the device complexity increases
Solution Approach 1:
The patent applies the Universality principle by designing an enhancer module that serves multiple functions: it contains the rotating refractive lens for dynamic lighting effects, incorporates a lighting device for illumination, and enables both indoor and outdoor projection capabilities. This multi-functional design achieves adaptability across different environments while consolidating components to manage overall device complexity
Solution Approach 2:
The patent implements the Nested doll principle by placing the lighting device and rotating refractive lens within the enhancer housing. The lighting device is positioned to illuminate the refractive lens, which is mounted on a rotating mechanism within the enhancer. This nested arrangement integrates multiple functional components into a compact unit, reducing overall device complexity while maintaining enhanced capabilities
3Illumination intensity
If a rotating refractive lens is added to create dynamic lighting effects, then the visual appeal is improved, but the mechanical complexity increases
Solution Approach 1:
The patent applies the Dynamics principle by using a motor-driven rotating mechanism for the refractive lens. This dynamic rotation capability allows the lens to change orientation continuously or in steps, creating varied refraction patterns and lighting effects. The mechanical complexity is managed by using a simple rotary motor rather than complex multi-axis positioning systems
Solution Approach 2:
The patent implements the Color changes principle through the rotating refractive lens that disperses light into different colors as it rotates. The refractive lens material and its rotation create spectral separation and color variations in the projected image, enhancing visual appeal through dynamic color effects without requiring multiple separate light sources or complex filtering mechanisms

AI summary
An indoor-outdoor projector has a housing, a slide holder and a projection lens assembly mounted on the housing, and an enhancer and a lighting device mounted in the housing. The enhancer has a mounting seat, a motor mounted on the mounting seat, and a refractive lens attached to a driving shaft of the motor and facing the projection lens assembly. The lighting device has a lighting end that can emit light. A slide with an image is inserted in the slide holder. The motor drives the refractive lens to rotate. The lighting device emits the light to pass through the rotating refractive lens, the slide, and the projection lens assembly to project a projection on a screen and to form dynamic lighting variations.
