Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lens options with various optical properties are provided to meet different consumer needs (viewing habits, lifestyle, aesthetic preferences), then the adaptability and versatility of the lens selection increases, but the device complexity and difficulty of selecting the optimal lens increases
Solution Approach 1:
The patent uses visual demonstrations with different colored lights (e.g., blue light, UV light) to show consumers how different lens types filter specific wavelengths. This allows consumers to intuitively understand optical properties without complex technical explanations, resolving the contradiction between providing versatile lens options and simplifying the selection process.
Solution Approach 2:
The patent introduces an intermediary demonstration device that visually translates complex optical properties into observable effects. This intermediary tool mediates between the technical specifications of multiple lens options and the consumer's understanding, allowing adaptability across different lens types while keeping the selection process simple through visual feedback.
2Loss of information
If detailed information about optical properties is provided to help consumers make informed decisions, then the loss of information is reduced, but the complexity of the information and time required for decision-making increases
Solution Approach 1:
The patent employs periodic switching between different light sources (e.g., alternating between blue light, UV light, and white light) to demonstrate various optical properties sequentially. This periodic demonstration provides complete information about lens characteristics while maintaining consumer engagement and reducing perceived complexity, thereby reducing both information loss and selection time.
Solution Approach 2:
The patent demonstrates only the most relevant optical properties for each consumer's specific needs rather than all possible properties. By applying partial action - showing only the necessary information about light transmission, blue light filtering, or UV protection based on consumer preferences - the system provides sufficient information without overwhelming the consumer, thus reducing selection time while maintaining information completeness.
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
This approach enables consumers to intuitively understand the benefits of different lenses, facilitating a more personalized and efficient selection process by demonstrating how optical properties affect visual perception and eye health, thereby streamlining the recommendation of suitable lenses.
Implementation Method 1
A demonstration tool including a light source and a light sensor is provided, which can measure the optical properties of the lens
Implementation Method 2
a light sensor for measuring light emitted from the light source
Data Source
AI summary
A method for demonstrating optical properties of a lens for spectacle glasses is disclosed in which a demonstration tool displays an optical property of the lens. The demonstration tool includes a light source and a light sensor receiving light from the light source. Placing a lens in the beam path between the light source and the light sensor changes the readout from the light sensor and the change in readout is converted into an optical property of the lens. An observer sees the optical property of the lens on a display.
