Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator rail alignment methods, such as string-based systems, are cumbersome and require multiple tools and adjustments, leading to inefficiencies and potential passenger discomfort due to misalignment.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If string-based alignment devices are used for rail point alignment, then alignment can be achieved, but the device complexity and ease of operation deteriorate due to requiring multiple clamps, strings, and tools
Solution Approach 1:
The patent combines multiple alignment functions (point alignment and plumb alignment) into a single integrated laser alignment device. The device merges the functions of multiple clamps and strings into one unified tool with a laser source, mounting mechanism, and alignment features that perform all necessary alignment operations simultaneously, eliminating the need for separate string-based alignment systems
Solution Approach 2:
The laser alignment device is designed with universal functionality to perform both point alignment and plumb alignment tasks. The device can be configured with different mounting options (clamps, magnets, adhesives) and includes features for establishing both horizontal/vertical reference lines and point-to-point alignment, making it a multi-functional tool that replaces several specialized alignment devices
2Measurement precision
If string-based alignment methods are used, then rail alignment is achieved, but productivity deteriorates due to requiring installers to move back and forth between rails making multiple adjustments
Solution Approach 1:
The device establishes laser reference lines and alignment points on the rails before final positioning and securing. The preliminary laser markings guide the installer in placing the rails in their correct positions and orientations before permanent installation, eliminating the need for repeated measurements and adjustments during the installation process
Solution Approach 2:
The laser beam serves as an intermediary reference that projects alignment information directly onto the rail surfaces and surrounding area. This visual intermediary provides continuous guidance during the alignment process, allowing installers to make precise adjustments without physically moving between reference points or using physical strings as intermediaries
3Measurement precision
If multiple alignment tools and strings are used, then alignment accuracy can be maintained, but ease of operation worsens due to the cumbersome nature of moving and managing multiple components
Solution Approach 1:
The patent integrates multiple alignment functions (point alignment and plumb alignment) into a single integrated laser alignment device. The device merges the functions of multiple clamps and strings into one unified tool with a laser source, mounting mechanism, and alignment features that perform all necessary alignment operations simultaneously, eliminating the need for separate string-based alignment systems
Solution Approach 2:
The device includes self-contained mounting mechanisms (clamps, magnets, or adhesives) that allow the alignment tool to attach and detach from rails without requiring additional tools or assistance. The laser system automatically provides alignment references when activated, and the device can be independently positioned and adjusted by a single installer without needing to manage separate components

AI summary
A method and device for elevator rail point alignment. A device body has a rear rail clamp and a front, angle alignable laser device. The laser mount provides for inversion alignment. In use, the device can be simply brought into true aim by focusing on an opposite target and marking the beam spot, inverting the tool on a aim and marking a second beam spot, and reaiming the laser to an intermediate spot.
