Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data charging cables with indicator lights are often obscured and difficult to locate in dark environments, as the light sources are typically small and positioned on the plugs, making it hard to find the data connector for charging.
Innovation Solution
A charging cable design featuring a transparent wire sleeve, LED lamp beads, opaque lampshades, and transparent optical fibers, along with a control switch, allows for adjustable lighting and improved visibility of the data connector in dark environments, enhancing aesthetics and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If indicator lights are designed on the plugs with small brightness, then the device structure remains simple, but the visibility in dark environments deteriorates
Solution Approach 1:
The patent transforms the lighting system from a two-dimensional surface indicator on the plug to a three-dimensional linear light guide along the cable. By embedding optical fibers within the cable core and using a light guide layer on the cable surface, the visibility is extended along the length of the cable rather than being confined to the plug area, solving the visibility problem without proportionally increasing complexity.
Solution Approach 2:
The patent introduces an intermediary light guide layer and optical fiber system between the LED light source and the external environment. The LED converts electrical energy to light, the optical fibers transmit this light along the cable, and the light guide layer distributes it visible to users, creating an efficient light transmission pathway that overcomes the brightness limitation of direct plug indicators.
2Illumination intensity
If LED lamp beads are added with optical fibers for enhanced visibility, then the visibility in dark environments improves, but the device complexity increases
Solution Approach 1:
The patent makes the optical fiber serve multiple functions: it acts as both a structural component of the cable (providing mechanical support and routing) and as a light transmission medium for visibility enhancement. This multi-functionality reduces the need for separate dedicated light-guiding structures, thereby limiting the increase in overall complexity while achieving improved visibility.
Solution Approach 2:
The patent uses a flexible light guide layer as a thin film structure that can be integrated into the cable assembly. This thin film approach allows the light distribution function to be added without significantly increasing the cable's volume or structural complexity, as the light guide layer conforms to the existing cable geometry and can be applied as a coating or laminate.
3Adaptability or versatility
If a control switch is added to control LED lighting, then the lighting effect becomes switchable and aesthetic, but the device complexity increases
Solution Approach 1:
The patent implements a self-service control mechanism where the user can manually activate or deactivate the lighting function through a simple switch or touch interface. This self-control approach eliminates the need for complex automatic sensing systems or multiple control modes, allowing the user to enable lighting only when needed, thus adding versatility without requiring sophisticated control circuitry.
