Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light strips are built in for visibility at night, then the flying disc is visible in dark environments, but it may harm the pet's teeth and affects safety
Solution Approach 1:
The patent extracts the harmful light strip component and replaces it with a point light source (LED) embedded in a light guide. This removes the harmful factor (light strip that can be bitten) while maintaining the illumination function for visibility in dark environments.
Solution Approach 2:
The patent introduces a light guide as an intermediary between the LED light source and the external environment. The light guide distributes the point light source's illumination across the disc surface, maintaining visibility while preventing direct exposure of the small LED component that could be bitten by pets.
2Extent of automation
If traditional sensor structures such as accelerometer sensor or MCU are used to control LED light assembly, then the lighting control is automated, but the circuit complexity and cost increase
Solution Approach 1:
The patent employs a centrifugal switch that automatically controls the LED light assembly based on the motion state of the flying disc itself. The switch leverages the disc's own rotational motion to activate or deactivate lighting, eliminating the need for external sensors or microcontrollers and achieving automated control through self-service mechanics.
Solution Approach 2:
The patent replaces complex electronic sensor systems (accelerometer, MCU) with a simple mechanical centrifugal switch. This mechanical system uses centrifugal force generated during disc rotation to open or close the circuit, providing automated lighting control with significantly reduced complexity and cost.
3Illumination intensity
If light strips are used for illumination, then the visibility is achieved, but the structure becomes complex and cost increases
Solution Approach 1:
The patent extracts the complex light strip structure and replaces it with a simple point light source (LED) combined with a light guide. This simplifies the overall structure while maintaining the illumination function, reducing both structural complexity and manufacturing cost.
Solution Approach 2:
The patent concentrates the light source into a small local point (LED) rather than distributing it along a strip. The light guide then distributes this localized light source across the necessary areas, achieving effective illumination with a simpler, more compact structure that reduces overall device complexity.
