Elevator Marking Device Using Laser Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator component mounting and maintenance processes are complex and require precise alignment, often resulting in noise during door operations and potential errors, especially for less experienced personnel.
Innovation Solution
A marking device with a light emission unit, such as a laser, is used to create visible markings on elevator components for precise positioning and characterization, facilitating alignment and maintenance by generating temporary markings that can be set in various directions, including using beam shaping means and adjustable fastening mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional mounting and maintenance methods are used for elevator components, then alignment and positioning require complex procedures and tools, but this increases the complexity of the process and reduces efficiency
Solution Approach 1:
The patent replaces complex mechanical alignment tools and procedures with an optical system. A light emission unit (laser) projects visible markings directly onto elevator components, eliminating the need for complex mechanical measurement and alignment tools, thereby simplifying the process while maintaining precision
Solution Approach 2:
The patent creates optical copies (light markings) of reference positions and alignment information directly on the target components. Instead of using physical templates or complex mechanical fixtures, the system projects light patterns that replicate the desired alignment information, making the process simpler and more efficient
2Manufacturing precision
If precise alignment of elevator components is achieved through traditional methods, then positioning accuracy can be maintained, but noise is generated during door operations
Solution Approach 1:
The patent uses optical fields (light) instead of mechanical contact and adjustment methods. The light emission unit projects alignment markings without physical contact, and the alignment is achieved through visual reference rather than mechanical forcing, thereby maintaining precision while avoiding noise-generating mechanical operations
3Adaptability or versatility
If less experienced personnel perform elevator component mounting and maintenance, then labor flexibility is improved, but errors and misalignment occur more frequently
Solution Approach 1:
The patent makes the alignment information self-evident through projected light markings. The system automatically provides visual guidance that is immediately understandable, eliminating the need for extensive training or interpretation skills. The markings themselves convey the alignment information directly, allowing less experienced personnel to perform tasks accurately by simply following the visual cues
Solution Approach 2:
The patent uses visible light markings (optical signals) to convey alignment information. The light emission creates high-contrast visual markers that are easily distinguishable and immediately recognizable, providing clear guidance regardless of the operator's experience level. The optical nature of the markings ensures they are visible and unambiguous
