Hanging Lamp with Toothed Guide Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanging lamps are difficult to assemble, disassemble, and maintain due to the need to handle heavy components at altitude, and they often require precise adjustment of the suspending cables for correct weight distribution and parallelism, making operations cumbersome and tool-dependent.
Innovation Solution
A hanging lamp design featuring a cylindrical inner body suspended by steel cables, with a larger outer cylindrical body that supports the diffuser and houses the inner body, allowing for adjustment of their relative positions using toothed guides, enabling assembly and disassembly without carrying the diffuser weight and without adjusting the suspending cables, and ensuring correct weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the diffuser is directly mounted on the lamp body using screws or similar constraining means, then the lamp structure is stable, but the assembly and disassembly operations become complex and require tools
Solution Approach 1:
The lamp is divided into separate modular components: the lamp body (inner cylindrical body) and the diffuser assembly (outer cylindrical body with diffuser). This segmentation allows the diffuser to be assembled and disassembled independently from the lamp body, eliminating the need for screws or other constraining means and simplifying maintenance operations.
2Ease of operation
If the lamp is suspended by steel cables, then the lamp can be mounted to the ceiling, but the correct weight balance and parallelism require precise adjustment of the suspending cables
Solution Approach 1:
The outer cylindrical body is designed to be movable relative to the inner cylindrical body along the suspension cables. This dynamic arrangement allows the diffuser assembly to automatically adjust its position to achieve correct weight balance and parallelism to the ceiling without requiring manual adjustment of the suspending cables themselves.
3Ease of operation
If the operator constrains the lamp by the steel cable holding the weight of the whole lamp during assembly, then the lamp can be positioned, but the operations become difficult when carried out at altitude
Solution Approach 1:
By separating the lamp into the inner cylindrical body (lamp body) and outer cylindrical body (diffuser assembly), the operator only needs to handle the lighter inner body during initial suspension and positioning, while the heavier diffuser assembly can be attached separately without requiring the operator to carry the entire lamp weight at altitude.
4Ease of operation
If the diffuser is assembled to the ceiling subsequently to the lamp fixing, then the lamp body is securely mounted, but the operator has to operate on the constraining means of the diffuser with tools
Solution Approach 1:
The diffuser assembly is designed as a separate outer cylindrical body that can be independently assembled with the diffuser, then attached to the inner cylindrical body without requiring tools. This segmentation allows the diffuser to be pre-assembled and then simply hung onto the lamp body, eliminating the need to operate screws or other constraining means at altitude.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies assembly and disassembly by allowing the diffuser to be handled separately from the lamp body, eliminates the need to adjust the suspending cables for weight balance, and facilitates maintenance without tools, ensuring easy and quick operations while maintaining correct weight distribution and parallelism to the ceiling.
Implementation Method 1
the outer cylindrical body has a bigger diameter than the inner cylindrical body and it is shiftable in a resting position onto the higher surface of the inner cylindrical body
Implementation Method 2
the means for adjusting the position include at least one toothed guide disposed on the outer cylindrical body and at least one surface provided with teeth on the inner cylindrical body engaging the guide in different positions
