Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rainbow projection lamps use multiple light sources, lenses and filter components, then the rainbow projection effect can be achieved, but the structure becomes complex and the volume increases
Solution Approach 1:
The patent extracts and removes unnecessary components from the traditional rainbow projection lamp structure. By eliminating lenses and filter components, and reducing multiple light sources to a single light source with an arc-shaped through-hole, the design achieves rainbow projection effect while significantly simplifying the overall structure.
Solution Approach 2:
The patent segments the light path by introducing an arc-shaped through-hole in the light-permeable plate. This segmentation allows different wavelengths of light to be separated and projected at different positions, creating the rainbow effect through a simplified single-component structure rather than requiring multiple integrated components.
2Reliability
If traditional rainbow projection lamps use multiple light sources and filter components, then the rainbow projection effect can be achieved, but the production cost increases
Solution Approach 1:
The patent removes expensive components such as lenses and filter components from the traditional design. By using a simple light-permeable plate with an arc-shaped through-hole and a single light source, the production cost is significantly reduced while maintaining the rainbow projection effect.
Solution Approach 2:
The patent replaces expensive optical components with a simple, inexpensive light-permeable plate structure. The arc-shaped through-hole design can be easily manufactured using cost-effective materials and processes, making the overall device much more affordable to produce.
3Reliability
If traditional rainbow projection lamps use complex device structure, then the rainbow projection effect can be achieved, but the volume of the lamp increases
Solution Approach 1:
The patent extracts and eliminates bulky components such as lenses and filter assemblies from the traditional rainbow projection lamp. The simplified structure using a light-permeable plate with an arc-shaped through-hole and single light source dramatically reduces the overall volume of the lamp while preserving the rainbow projection functionality.
4Reliability
If traditional rainbow projection lamps use multiple light sources and complex components, then the rainbow projection effect can be achieved, but the structure becomes complex and maintenance difficulty increases
Solution Approach 1:
The patent removes complex components such as lenses, filter assemblies, and multiple light sources that require specialized maintenance. The simplified design with a single light source and arc-shaped through-hole in a light-permeable plate makes the device much easier to maintain and repair, reducing technical barriers for users.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a simple, cost-effective rainbow projection with rich and wonderful color effects by diffracting light through arc-shaped holes, offering a versatile and user-preferred lighting experience.
Implementation Method 1
Since wavelengths of different lights are different, and the lights will be diffracted when they pass through a slit, the positions of the diffracted lights will be different when the lights pass through the arc-shaped through-hole of the light-permeable plate
