Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for elevator rail systems lack efficient alignment and secure mounting of brackets on walls, particularly in cases of angular misalignment and varying wall tolerances, which can lead to instability and misalignment of rail systems.
Innovation Solution
A fastening system comprising two fastening elements with a clamping plate, a receiving sleeve, and an angularly movable ball joint, along with an anchor bolt and nuts, allowing for adjustable alignment and secure clamping of brackets between the fastening elements, compensating for angular misalignment and positioning tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional fastening systems are used for mounting brackets, then the mounting process is simple, but alignment precision and compensation for angular misalignment are insufficient
Solution Approach 1:
The fastening system incorporates a ball joint mechanism that allows dynamic adjustment and movement during the alignment process. The ball joint enables the bracket to be positioned at various angles and orientations before final tightening, providing the flexibility needed to achieve precise alignment while compensating for wall irregularities and angular misalignment.
Solution Approach 2:
The system allows for parameter changes in positioning and orientation during assembly. The adjustable fastening elements can be moved along the anchor bolt to change the vertical and horizontal position of the bracket, and the ball joint enables angular parameter adjustments. This flexibility resolves the contradiction by allowing precise alignment through parameter adjustment rather than requiring extremely tight manufacturing tolerances.
2Adaptability or versatility
If adjustable alignment mechanisms are added to compensate for wall irregularities, then alignment flexibility improves, but the fastening system becomes more complex
Solution Approach 1:
The ball joint provides dynamic adaptability by allowing the fastening system to adjust to various wall conditions and angular misalignments. This single mechanical element provides both rotational and spherical movement capabilities, enabling the system to adapt to irregularities without requiring multiple separate adjustment mechanisms, thus limiting the increase in complexity.
Solution Approach 2:
The fastening system is designed with multi-functional elements that perform multiple alignment tasks. The ball joint simultaneously handles angular misalignment, positional adjustment, and orientation correction. The combination of the adjustable fastening elements and ball joint creates a universal mounting solution that can accommodate various wall conditions, achieving high adaptability while keeping the overall system structure relatively simple.
3Reliability
If multiple fastening elements are used to ensure stability, then mounting reliability improves, but the complexity of assembly increases
Solution Approach 1:
The system merges multiple fastening elements into a coordinated assembly that works together through a unified adjustment mechanism. The fastening elements are positioned at strategic locations and connected through the ball joint, allowing them to function as an integrated unit. This merging approach ensures stability through multiple contact points while maintaining assembly simplicity because all elements can be adjusted and tightened in a systematic sequence rather than requiring independent adjustment of each element.
4Manufacturing precision
If the bracket is rigidly fixed to achieve precise alignment, then alignment accuracy improves, but the ability to compensate for angular misalignment is lost
Solution Approach 1:
The system transitions from a rigid fixed state to a dynamic adjustable state during assembly. The ball joint and movable fastening elements allow the bracket to be positioned and aligned with precision while maintaining the capability to compensate for angular misalignment. Once the optimal position is achieved, the system can be rigidly secured, thus achieving both alignment accuracy and compensation capability through the temporary dynamic phase during installation.
