Floor Lamp Pivot Axis Recess Mounting Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor lamps lack simple and cost-effective solutions for adjusting the alignment of the lamp head, often leading to material deformation and damage due to complex and costly bearing systems.
Innovation Solution
A floor lamp design featuring a pivot axis defined by recesses on the column and a support element, with adjustment means including a screw connection offset to the pivot axis, allowing precise alignment without deforming sensitive components, and incorporating a stop element for limiting pivoting range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex bearings are used to adjust lamp head orientation, then alignment adjustment capability is improved, but device complexity and cost increase
Solution Approach 1:
The column is segmented into modular components with recesses that form a receptacle, allowing the lamp head to be separately mounted and adjusted. This segmentation enables independent adjustment of the lamp head orientation without requiring a complex integrated bearing system.
Solution Approach 2:
The lamp head is designed to be movable relative to the column through the recess-receptacle interface, allowing dynamic adjustment of orientation. The screw connection provides a mechanism to lock the lamp head in desired positions while maintaining the ability to adjust between positions.
2Ease of operation
If pressure-based screw connections are used to secure the lamp head, then alignment adjustment is enabled, but material deformation and stress damage occur
Solution Approach 1:
The recess in the column and the corresponding support element on the lamp head act as intermediaries that distribute the mechanical stress during adjustment. This intermediary interface prevents direct stress concentration on the lamp head mounting points, reducing the risk of material deformation and damage.
3Stability of the object's composition
If the lamp head is fixed in position, then structural stability is maintained, but adaptability to different orientations is lost
Solution Approach 1:
The mounting system transitions from a fixed connection to a dynamic interface where the lamp head can be adjusted between multiple orientations. The recess-receptacle配合 with the screw connection allows the structure to be stable during use but adaptable during adjustment.
Solution Approach 2:
The system allows change in the angular parameter of the lamp head orientation while maintaining structural integrity. The recess geometry and screw positioning enable controlled parameter changes in orientation without compromising the overall structural stability of the lamp.

AI summary
In a floor lamp (100) with a substantially vertically extending column (10) and a lamp head (30) held at the upper end on the column (10), the mounting of the lamp head (30) on the column (10) defines a substantially horizontal pivot axis (I) about which the lamp head (30) can be pivoted, wherein adjusting means are provided by which the pivot position of the lamp head (30) with respect to the pivot axis (I) can be adjusted.
