Lamp Stand Mechanism for One-Hand Height and Orientation Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting apparatuses require separate and independent operations for adjusting the lamp head's height and circumferential orientation, which can be cumbersome and time-consuming.
Innovation Solution
A lighting apparatus with a central shaft and stand design that allows simultaneous adjustment of the lamp head's height and circumferential orientation by sliding and rotating the stand relative to the central shaft, enabling ergonomic and efficient adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lamp head's height and circumferential orientation are adjusted through separate and independent operations, then the structural design is simple, but the ease of operation deteriorates and adjustment becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges the adjustment of lamp head height and circumferential orientation into a single integrated operation. The lamp head assembly is designed to simultaneously change both its vertical position and angular orientation when rotated about the central axis, eliminating the need for separate adjustment mechanisms and operations.
Solution Approach 2:
The patent introduces dynamic adjustment capability where the lamp head can be rotated about the central axis to simultaneously achieve both height adjustment and circumferential orientation change. This dynamic mechanism allows continuous variation of both parameters through a single degree of freedom, improving operational flexibility.
2Adaptability or versatility
If the lamp head and battery box are in a fixed relative position, then the manufacturing precision is maintained, but the adaptability deteriorates as separate operations are required for different adjustment scenarios
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that allow the lamp head to be positioned at various heights and orientations while maintaining precise control. The rotatable connection between the lamp head assembly and the central axis enables continuous adjustment of both vertical and angular positions, providing adaptability without sacrificing positioning precision.
Solution Approach 2:
The patent segments the lighting apparatus into functionally independent modules: the battery box, the central axis, and the lamp head assembly. This modular design allows each component to be manufactured with precise tolerances independently, while the standardized connection interfaces maintain overall assembly precision while enabling flexible configuration.

AI summary
A lighting apparatus comprises a lamp head, a central shaft, and a stand. The lamp head and the stand are each connected to the central shaft. While the lamp head is maintained in a fixed relative position to the central shaft, the stand can not only slide axially relative to the central shaft to adjust an illumination height of the lamp head, but can also rotate circumferentially relative to the central shaft to adjust a circumferential lighting orientation of the lamp head. The axial sliding and circumferential rotation of the stand relative to the central shaft correspondingly adjusts the illumination height and circumferential lighting orientation of the lamp head, operation is convenient and simple.
