Moving Head Lamp Carrying Handle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moving head lamps are bulky and heavy, making them difficult to handle safely due to their weight and center of gravity positioning, which increases the risk of tilting during handling, especially as they become more powerful and larger.
Innovation Solution
A carrying handle is arranged on the lamp head carrier between the lamp head and the lamp base, with elongate grip sections parallel to the axes of rotation, providing a higher and more stable grip to reduce tilting risks and facilitate safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handles are arranged on the lamp base, then a good grip is provided for handling, but the center of gravity is far below the handle position increasing the risk that the unit may tilt during handling
Solution Approach 1:
The handle is repositioned from the horizontal plane of the lamp base to the vertical plane of the lamp head carrier, extending upward above the lamp head. This dimensional relocation moves the handle closer to the center of gravity vertically, reducing the tilting moment arm while maintaining horizontal accessibility for gripping.
2Illumination intensity
If moving head lamps become more powerful with increased illumination, then illumination intensity is improved, but the lamps become increasingly larger and heavier making them more difficult to handle safely
Solution Approach 1:
The handle is pre-positioned on the lamp head carrier above the lamp head, preparing the lamp for easy lifting before handling begins. This preliminary arrangement of the lifting interface allows single-person operation even as the lamp's weight increases due to more powerful illumination components.
3Ease of operation
If handles are arranged on the lamp base, then handling is provided, but the position is far below the centre of gravity increasing risk that the unit may tilt during handling
Solution Approach 1:
The lamp head carrier serves as an intermediary structure that supports the handle above the lamp head. This intermediary positioning allows the handle to be coupled to a stable structural element (the carrier) while being located at a height that improves handling safety by reducing the tilting moment relative to the center of gravity.
