Floodlight Ball Joint Steering for Tool-Free 3D Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floodlights are difficult to adjust to specific illumination angles after installation, requiring removal and reinstallation for angle adjustments.
Innovation Solution
A floodlight with a steering structure comprising a spherical steering head and hemispherical groove, secured by a compression member with a bell-mouth shaped hole, allowing three-dimensional adjustment without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a floodlight is fixed on a support base with a U-shaped bracket allowing rotation around a single axis, then the floodlight can be adjusted to a specific illumination angle during installation, but once installed the user cannot rotate the floodlight around multiple axes and must remove and reinstall it to change the illumination angle
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that transitions from a fixed single-axis rotation to a multi-axis rotational system. The floodlight assembly includes a first rotation mechanism for azimuth adjustment and a second rotation mechanism for elevation adjustment, allowing the floodlight to be dynamically repositioned in multiple directions after installation without removal.
Solution Approach 2:
The patent adds another dimension of movement by introducing elevation rotation in addition to the original azimuth rotation. The second rotation mechanism enables the floodlight to rotate around an axis that is not parallel to the first rotation axis, thereby expanding the adjustment from one-dimensional (single-axis) to two-dimensional (multi-axis) movement.
2Adaptability or versatility
If a floodlight is installed with a fixed mounting structure, then the installation is simple and stable, but the user cannot adjust the illumination angle after installation without removing the floodlight
Solution Approach 1:
The patent divides the mounting structure into segmented, independent rotation mechanisms. The first rotation mechanism and second rotation mechanism are separate and can be independently adjusted, allowing complex multi-axis positioning while maintaining relative simplicity in each individual mechanism. This segmentation enables adaptability without proportionally increasing overall complexity.
3Adaptability or versatility
If a floodlight uses a simple single-axis rotation mechanism, then the device complexity is low, but the floodlight can only be adjusted around one axis and requires removal for angle changes
Solution Approach 1:
The patent merges two rotation mechanisms into a single integrated floodlight assembly. The first rotation mechanism (for azimuth) and second rotation mechanism (for elevation) are combined in such a way that both functions are available within one compact structure, achieving multi-axis rotation without proportionally increasing the overall device complexity.
