Reading Lamp Swiveling Joint and Magnetic Power Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional detachable reading lamps for furniture pose challenges due to the need for large caliber interfaces and exposed connections, affecting the visual appearance, collecting dirt, and risking electric shock when detached.
Innovation Solution
A reading lamp design featuring a swiveling joint assembly and a magnetic power interface set within a hollow support column, allowing for polyaxial and rotational movement, and secure magnetic electrical connection to an external power source without visible cords or protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large caliber interface with protruding connecting bar or button is used for electrical connection, then electrical connectivity is ensured, but the visual appearance is affected and dirt accumulation occurs
Solution Approach 1:
The electrical connector is nested within the hollow interior of the support column, with the connecting bar positioned inside the column rather than protruding outward. This nesting approach maintains electrical connectivity while eliminating the visual impact and dirt accumulation issues of exposed connectors.
Solution Approach 2:
The connecting button is extracted from the exterior surface and repositioned to the interior surface of the support column's hollow interior. This extraction removes the problematic protruding element from the external view while preserving its electrical connection function.
2Reliability
If a large caliber interface is used for electrical connection, then electrical connectivity is ensured, but the interface exposes holes or slots that risk electric shock when detached
Solution Approach 1:
Both the male and female electrical connectors are nested within the hollow interior of the support column. This nesting creates a protected environment that isolates the electrical contacts from external access, eliminating the electric shock risk while maintaining reliable connectivity when the lamp is attached.
3Use of energy by moving object
If external power source connection with main lead or power cord is used, then power supply is achieved, but the overall visual appearance is affected and use convenience is reduced
Solution Approach 1:
The main lead or power cord is completely removed from the design. Instead, the lamp utilizes the existing electrical installation base within the furniture item, extracting the power supply function from external connections and integrating it into the furniture's internal electrical system.
4Use of energy by moving object
If external power source connection with main lead or power cord is used, then power supply is achieved, but use convenience is reduced due to presence of cords and connection to external socket
Solution Approach 1:
The external power cord and socket connection are removed, replacing them with an integrated electrical connection to the furniture item's internal power source. This eliminates the need for plugging and unplugging cords, significantly improving ease of operation.

AI summary
A reading lamp includes a lamp top set having a tubular housing and a support column having a first end and a second end opposite the first end. The support column may include a column wall defining a hollow interior of the support column. A swiveling joint assembly may be positioned between and join the tubular housing and the first end of the support column, such that the swiveling joint assembly enables one or more of polyaxial and rotational movement of the tubular housing relative to the support column or the swiveling joint assembly.
