Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If built-in power sources and light sources are added to luminous sporting goods, then luminous effect can be achieved independently of sunlight, but product cost increases and weight increases affecting reliability and balance
Solution Approach 1:
The system is divided into two separate components: a portable light supplying device (UV/visible light source) and the light receiving sporting goods (phosphor-coated items). This segmentation allows the sporting goods to remain lightweight while the light source is provided externally, resolving the contradiction between achieving sunlight-independent luminescence and maintaining low weight.
Solution Approach 2:
The patent introduces an intermediary portable light supplying device that contains the power source and light emitting components. This intermediary device acts as a separate entity that temporarily provides light to the sporting goods, avoiding the need to integrate heavy batteries and light sources into the sporting goods themselves.
2Adaptability or versatility
If built-in power sources are added to luminous sporting goods, then luminous effect can be achieved independently of sunlight, but product cost increases
Solution Approach 1:
By separating the light supplying function from the sporting goods, the patent avoids the high cost of integrating built-in power sources into each individual sporting good. The portable light supplying device can serve multiple sporting goods, reducing per-unit cost.
3Adaptability or versatility
If built-in power sources are added to luminous sporting goods, then luminous effect can be achieved independently of sunlight, but reliability decreases due to added components
Solution Approach 1:
The patent separates the complex power supply and light emission components into a dedicated portable device, leaving the sporting goods themselves simple and reliable phosphor-coated items. This segmentation isolates the complexity and potential failure points in the light supplying device, protecting the reliability of the sporting goods.
Solution Approach 2:
The portable light supplying device serves as an intermediary that temporarily provides light without becoming a permanent part of the sporting goods. This temporary interaction avoids the reliability issues associated with permanently integrated power sources and complex assemblies.
4Adaptability or versatility
If built-in power sources are added to luminous sporting goods, then luminous effect can be achieved independently of sunlight, but balance and shape are affected
Solution Approach 1:
The patent separates the light source from the sporting goods, allowing the sporting goods to maintain their original shape, size, and design without any modifications. The portable light supplying device externally provides illumination without affecting the sporting goods' physical characteristics.
5Ease of manufacture
If sunlight irradiation is required for fluorescence, then simple phosphor coating is sufficient, but fluorescence effect is greatly reduced in rainy or cloudy days
Solution Approach 1:
The patent introduces a portable light supplying device as an intermediary that provides UV/visible light under any weather conditions. This intermediary replaces the dependency on natural sunlight, allowing the simple phosphor coating to function reliably regardless of weather, thus resolving the contradiction between manufacturing simplicity and weather adaptability.
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
Enables consistent fluorescence in various weather conditions, improving user experience with a lightweight, cost-effective, and reliable solution that maintains the sporting goods' balance and functionality.
Implementation Method 1
The phosphors after absorbing sunlight will be slowly released in a fluorescent way, namely fluorescence radiation
Implementation Method 2
the light emitting device emits ultraviolet light and/or visible light on the luminous sporting goods, so that the phosphor contained in the luminous sporting goods is excited to produce the visible light effect

AI summary
A light supplying device includes a box and a light emitting device. The box is provided with a cavity and configured to be fully closed or semi-closed, and the light emitting device is arranged in the box and configured to provide ultraviolet light and/or visible light. The device supplies light to a light receiving device such as luminous sporting goods to excite the fluorescent agent on the surface to produce fluorescence effect and shows luminous effect at night or in the dark. In such a way, the light receiving device such as the luminous sporting goods may receive the light anytime and anywhere, without sunlight irradiation, thereby improving the user's experience. Moreover, the device is convenient and portable, and has simple structure and high efficiency.
