Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing consumer products, such as lamps, are not designed for longevity and often require plug-in chargers, which compromise water-resistance when used in humid environments, and solar and wireless charging systems are inefficiently integrated, leading to uneven weight distribution and instability.
Innovation Solution
A module with a water-resistant housing that integrates a solar panel and charging coil on the same exterior face for simultaneous solar and wireless charging, allowing for a compact design and easy component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If solar panel and charging coil are arranged on different parts of the device, then both solar and wireless charging can be enabled, but the device size increases and weight distribution becomes uneven causing instability
Solution Approach 1:
The patent merges the solar panel and charging coil into the same housing space, with the solar panel positioned on the exterior face and the charging coil located inside the housing adjacent to the solar panel. This integration allows both solar and wireless charging functions to coexist without requiring separate external surfaces, thereby maintaining device compactness and balanced weight distribution while ensuring stability.
2Volume of moving object
If plug-in chargers are used to minimize device size, then device compactness is improved, but water-resistance is compromised when used in humid environments
Solution Approach 1:
The patent implements self-service charging through integrated solar and wireless charging capabilities that do not require external plug-in connections. The solar panel captures sunlight and the charging coil enables wireless power transfer, both of which can occur through the housing without compromising the seal integrity. This eliminates the need for removable plugs that would compromise water-resistance, allowing the device to maintain both compact size and reliable water-protection.
3Volume of moving object
If solar panel is arranged on exterior face for wireless charging, then device compactness is improved, but charging efficiency may be reduced due to space constraints
Solution Approach 1:
The patent utilizes the interior space of the housing to position the charging coil in a different spatial dimension relative to the exterior solar panel. By arranging the charging coil inside the housing adjacent to the solar panel rather than requiring additional external surface area, the design achieves compactness while maintaining effective charging alignment. The solar panel remains on the exterior face for optimal sunlight exposure, while the internal coil positioning enables efficient wireless energy transfer through the housing wall.
