Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent rotation of the lamp holder in omnidirectional table lamps can lead to breakage of the connection part between the lamp handle and holder, reducing the service life of the lamp.
Innovation Solution
A table lamp design with a curved base and an adjustment component that changes the center of gravity, allowing the illumination angle to be adjusted by varying the position of poises on a lamp shank, rather than through rotation of the lamp holder, thereby avoiding breakage and extending the lamp's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lamp holder is rotated to adjust the illumination angle, then the illumination angle can be changed, but the connection part of the lamp handle and lamp holder may break due to frequent rotations
Solution Approach 1:
Instead of rotating the lamp holder to adjust the illumination angle, the patent inverts the approach by rotating the base. The lamp holder remains stationary and is fixedly connected to the lamp handle, while the base rotates relative to the placement surface. This inversion transfers the rotational stress from the fragile lamp holder connection to the more robust base connection, eliminating the breakage problem while maintaining illumination angle adjustability.
Solution Approach 2:
The patent segments the rotation function from the illumination function. The base is designed to rotate independently to adjust the illumination angle, while the lamp holder and lamp handle form a separate fixed connection unit. This segmentation allows the rotation operation to be performed on the base without affecting the structural integrity of the lamp holder connection, thereby solving the reliability issue.
2Stability of the object's composition
If the base has a planar contact surface for stable placement, then the table lamp can be placed steadily, but the illumination angle cannot be adjusted without rotating the lamp holder
Solution Approach 1:
The patent applies dynamics by making the base rotatable relative to the placement surface. The base maintains stable placement through friction and gravity while allowing controlled rotation to adjust the illumination angle. This dynamic design enables the base to transition between stable placement and adjustable orientation, resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The patent introduces a new dimension for adjustment by allowing the base to rotate in the horizontal plane rather than rotating the lamp holder vertically. This dimensional change provides a new degree of freedom for illumination angle adjustment while maintaining the stable planar contact between the base and placement surface.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively adjusts the illumination angle without risking breakage of the lamp holder, thereby prolonging the service life of the table lamp and ensuring stable operation.
Implementation Method 1
the adjustment component is capable of adjusting the center of gravity of the table lamp by varying the center of gravity of the adjustment component, to thereby change a contact position of the bottom surface of the base and the placement surface
Implementation Method 2
the poises or the lamp shank has magnetism such that the poises can be attracted to the lamp shank
Implementation Method 3
the magnetism is ferromagnetism, and the lamp shank or the poises are made of iron

AI summary
A table lamp including a base, a lamp handle, a lamp holder provided with a light source and an adjustment component. The base can be placed on a placement surface, and a bottom surface of the base is a curved surface. The adjustment component can adjust the center of gravity of the table lamp by varying the center of gravity thereof, to thereby change a contact position of the bottom surface of the base and the placement surface, and thus change the illumination angle of the lamp holder. Since this technical solution adjusts the illumination angle of the lamp holder by adjusting the center of gravity of the table lamp instead of rotating the lamp holder, it solves the problem of breakage of the connection part of the lamp handle and the lamp holder caused by rotation of the lamp holder.
