Elevator Car Support Jig Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator car support jigs are cumbersome and difficult to install in limited shaft spaces due to their weight and the need for multiple clips, making adjustments and assembly challenging.
Innovation Solution
A support jig with a first member and a second member detachably fixed to the car rail, featuring adjustable clamping assemblies and inclined edges to distribute weight and facilitate alignment, allowing for easier installation and adjustment of the elevator car's position and posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mounting member is made large enough to accommodate multiple clips for supporting the elevator car weight, then the weight-bearing capacity is improved, but the weight of the support jig increases and it becomes difficult to move in the limited shaft workspace
Solution Approach 1:
The support jig is divided into a mounting member and a separate support member. The mounting member is lightweight and can be easily moved, while the support member provides the necessary weight-bearing capacity. This segmentation allows the mounting member to be maneuvered in the limited shaft workspace without requiring excessive weight, while still achieving the required strength through the combined structure.
Solution Approach 2:
The support member acts as an intermediary between the mounting member and the elevator car. Instead of the mounting member directly bearing the full weight of the elevator car, the support member serves as a mediator that distributes and supports the load, allowing the mounting member to remain lightweight and easily movable.
2Reliability
If multiple clips are used to support the elevator car weight, then the reliability of weight support is improved, but the device complexity increases making installation more difficult
Solution Approach 1:
The function of multiple clips is segmented between the mounting member (which provides attachment points) and the support member (which provides the primary weight-bearing structure). This segmentation simplifies the overall installation process compared to attaching multiple clips directly to a single large mounting member, as the support member can be positioned and secured as a unified component.
Solution Approach 2:
The mounting member and support member are combined into a coordinated system where the support member integrates the weight-bearing function that would otherwise require multiple separate clips. This merging reduces the number of separate components that need to be individually installed and positioned, thereby reducing installation complexity while maintaining weight support reliability.
3Manufacturing precision
If the entire support base is moved for height and posture adjustment, then the positioning precision is improved, but the ease of operation deteriorates due to the heavy weight and limited workspace
Solution Approach 1:
The adjustment function is segmented from the weight-bearing function. The mounting member can be adjusted for height and posture independently by moving only this lightweight component, while the support member remains stationary and provides stable weight support. This segmentation enables precise positioning adjustments without the difficulty of moving the entire heavy support structure.
Solution Approach 2:
The system transitions from a static, monolithic support base to a dynamic, modular configuration where the mounting member can be independently repositioned. This dynamic arrangement allows the mounting member to be moved and adjusted with ease during installation, and then locked into position, achieving both ease of operation and positioning precision.
