Floodlight Telescopic Post Damper Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The telescopic posts in existing floodlights with dampers for biasing force face issues such as decreased biasing force over time due to gas escape and difficulty in observing the damper's condition, requiring major repairs and making maintenance challenging.
Innovation Solution
The floodlight design includes a telescopic post with a damper housed in a cylinder and piston, where the piston is fixed to one post and the cylinder to another, with the damper located outside for easy maintenance and protection from external damage, and multiple dampers are provided to facilitate smooth movement and detect scratches early.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the damper is arranged inside the telescopic post, then the structure is compact, but the maintenance becomes difficult and the rod condition cannot be observed
Solution Approach 1:
The damper rod is extracted from the internal arrangement and repositioned to extend externally from the telescopic post. This allows the rod to be easily accessible for observation and maintenance while the cylinder remains mounted inside the post structure, achieving a balance between compactness and serviceability.
Solution Approach 2:
Instead of the conventional arrangement where the rod is internal and cylinder external, the patent inverts this by making the rod external and cylinder internal. This inversion solves the maintenance accessibility problem while maintaining structural compactness.
2Ease of operation
If the telescopic post is extended and contracted frequently, then the functionality is improved, but the damper rod may be scratched and gas may escape
Solution Approach 1:
The damper rod is positioned to extend externally before any telescopic operation occurs, allowing for preliminary inspection of the rod surface. This enables early detection of scratches or damage that could compromise seal integrity during subsequent extension and contraction operations.
Solution Approach 2:
The external positioning of the rod allows the system to perform self-inspection functionality, where the rod's condition can be visually assessed without disassembly, enabling early maintenance before gas escape occurs.
3Ease of repair
If the damper rod is positioned externally, then the maintenance becomes easy and observation is possible, but the structure becomes more complex
Solution Approach 1:
The damper is segmented into two functional parts: the cylinder remains integrated inside the telescopic post structure, while the rod extends externally. This segmentation allows the stationary cylinder to maintain structural integration while the moving rod provides external accessibility, reducing overall system complexity.

Function Achieved in This Case
This configuration allows for easy maintenance and detection of potential failures in the damper, ensuring smooth telescopic movement and preventing biasing force loss, while enabling the telescopic post to extend and contract smoothly without hindrance.

AI summary
One purpose is to smoothly raise and lower a telescopic post used in a floodlight. There is provided a floodlight that includes: a telescopic post that has a plurality of posts whose outer diameters are made gradually smaller, into which the posts can be loosely fitted, and that can be extended and contracted in an up-down direction; a lighting unit attached to the post located on the innermost side; a raising and lowering unit that extends and contracts, in the up-down direction, the posts in conjunction with each other; a base that the post located on the outermost side is fixed to; and dampers that connect a side surface of the post located on the outermost side and a side surface of the post located on the second outermost side.
