Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a gauge that can be conveniently and precisely aligned with elevator guide rails while offering cost savings in production without compromising functionality, as existing gauges require careful alignment and additional clamping for fixation.
Innovation Solution
A jig with an L-shaped base body featuring marks for rope interaction, magnetic elements for temporary fixation, and a guide shoe for precise alignment, allowing for quick rough alignment and sensitive adjustment without additional clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional gauges are used for aligning elevator guide rails, then alignment precision can be achieved, but additional clamping operations are required and manufacturing costs are higher
Solution Approach 1:
The patent replaces the mechanical clamping system with a magnetic field-based fixation system. Magnetic elements (such as magnets or magnetizable components) are integrated into the gauge to provide temporary holding force during alignment operations, eliminating the need for additional clamping screws or mechanical fasteners. This substitution reduces manufacturing complexity and cost while maintaining alignment precision.
Solution Approach 2:
The gauge is designed with self-aligning and self-holding characteristics through the integration of magnetic elements that automatically attract to the guide rail or accompanying magnetic components. This self-service mechanism eliminates the need for manual clamping operations and reduces the number of separate parts required, thereby lowering manufacturing costs while preserving precision.
2Reliability
If additional clamping screws are used to secure the gauge, then fixation reliability is improved, but device complexity and assembly time increase
Solution Approach 1:
The patent extracts and removes the clamping screws and associated mechanical fastening components from the gauge system. The magnetic elements provide the necessary fixation function without requiring these additional components, thereby simplifying the device structure and reducing the number of parts while maintaining reliable fixation during alignment operations.
Solution Approach 2:
The magnetic elements serve multiple functions: they provide temporary holding force during alignment, enable sensitive adjustment without permanent fixation, and eliminate the need for separate clamping mechanisms. This multi-functionality reduces device complexity while maintaining fixation reliability.
3Stability of the object's composition
If the gauge is firmly clamped to the guide rail, then stability is improved, but ease of adjustment during alignment is reduced
Solution Approach 1:
The patent implements a dynamic fixation system using magnetic elements that provide variable holding force. The magnetic force is sufficient to maintain gauge stability during most operations but can be easily overcome by manual adjustment forces, allowing the gauge to be repositioned sensitively during alignment. This dynamic characteristic enables both stability and ease of adjustment without requiring separate clamping and loosening operations.
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
Enables efficient and precise alignment of elevator guide rails with reduced production costs, as the jig can be pre-assembled and aligned magnetically, freeing the fitter's hands for precise adjustments before final clamping.
Implementation Method 1
one of the extensions is provided with at least one magnetic element that is strong enough to secure the teaching to the guide rail at least for the duration of its alignment, without the need for additional clamping
