Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless power supply systems for lamps, especially spherical lampshades, face challenges in quickly and effectively aligning the receiver coil with the transmitter coil due to the randomness of the lamp's positioning, leading to inefficient power transmission.
Innovation Solution
A wireless power supply lamp design featuring a movable independent unit within the lampshade, utilizing gravity or magnetic forces to align the receiver coil with the transmitter coil, allowing for efficient power transmission regardless of the lampshade's orientation on the base, which can include a motorized or manually adjustable base for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lampshade is randomly positioned on the base, then the lamp can be placed in various orientations for flexibility, but the receiver coil and transmitter coil cannot be aligned effectively for efficient power transmission
Solution Approach 1:
The independent unit containing the receiver coil is made movable within the lampshade rather than being fixed. This allows the unit to dynamically adjust its position and orientation in response to gravitational force, automatically aligning the receiver coil with the transmitter coil on the base regardless of how the lampshade is placed. The dynamic adjustment resolves the contradiction by maintaining alignment reliability while preserving placement flexibility.
Solution Approach 2:
The system uses the lampshade's own gravitational force to drive the automatic alignment of the receiver coil with the transmitter coil. The independent unit moves under gravity's influence to achieve optimal positioning without requiring external actuators or complex control systems. This self-service approach enables reliable power transmission across various placement orientations while keeping the system simple.
2Device complexity
If the receiver coil is fixed in the lampshade, then the structure is simple, but the coil alignment with the transmitter coil is slow and ineffective when the lamp is randomly positioned
Solution Approach 1:
The receiver coil is mounted on an independent unit that can move freely within the lampshade rather than being fixed. This dynamic configuration allows the coil to quickly align with the transmitter coil when the lamp is placed on the base, significantly improving alignment speed while adding minimal structural complexity. The movement is driven by gravitational force, requiring no additional motors or actuators.
3Measurement precision
If magnetic members are added to the independent unit and base, then the alignment accuracy and speed improve, but the device complexity increases
Solution Approach 1:
Magnetic members are introduced as intermediary elements between the independent unit and the base to enhance the alignment process. These magnets create attractive forces that guide the independent unit to its correct position more quickly and accurately. While this adds components, the magnetic alignment mechanism is simple and requires no complex control systems, balancing improved precision with acceptable complexity increase.

AI summary
A wirelessly powered self-aligning lamp includes: a lampshade, which is at least partially made of a light-transmitting material; an individual component, which is movably arranged in the lampshade and on which a light source and a wireless power receiving coil are fixedly mounted, the receiving coil being used to power the light source; and a base fixedly provided with a wireless power transmitting coil that cooperates with the wireless power receiving coil of the individual component. When the lampshade is positioned at will on the base, the individual component in the lampshade has a movement trend relative to the base to align the receiving coil on the individual component with the transmitting coil on the base. In the lamp of the present application, the lampshade is internally provided with a gravity or magnetic adjustment mechanism that enables the power coil to be self-aligned.
