Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Overhead cranes are limited by fixed rails, restricting their operational range, and there is a need for a safe and efficient method to extend this range by connecting beams without compromising safety.
Innovation Solution
An interlock mechanism with a locking pin and arm system that transitions stop mechanisms between blocking and unblocking positions, allowing a first beam to be securely and releasably connected to a secondary beam, ensuring safe transfer of the trolley hoist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed rails are used for overhead cranes, then the crane structure is stable and reliable, but the operational range of the crane is limited
Solution Approach 1:
The beam system is divided into separate beam sections that can be independently positioned and connected. The interlock mechanism allows beams to be segmented into modular units that can be assembled to extend the operational range of the crane while maintaining structural stability through standardized connection points.
Solution Approach 2:
The beam connection system transitions from a static fixed-rail configuration to a dynamic, reconfigurable system. The interlock mechanism enables beams to be connected and disconnected, allowing the crane's operational range to be adjusted dynamically based on material handling requirements while maintaining reliability through secure mechanical engagement.
2Adaptability or versatility
If beams are connected to extend crane range, then operational flexibility is improved, but safety risks increase
Solution Approach 1:
The interlock mechanism incorporates safety features that prevent accidental disconnection or improper engagement before critical failures can occur. The design includes interlocking elements and engagement indicators that ensure beams are properly connected and locked before the crane operates, preventing safety incidents related to beam separation.
Solution Approach 2:
The interlock mechanism is designed to self-verify proper engagement through built-in indicators and mechanical interlocks that automatically confirm secure connection. The system provides inherent safety through its design, where the beam connection status can be readily verified without additional complex monitoring systems, ensuring reliability through self-checking capabilities.
3Reliability
If a locking pin mechanism is used, then beam connection reliability is improved, but the complexity of the interlock system increases
Solution Approach 1:
The locking pin mechanism is integrated with the beam structure itself, merging the connection function into the beam design. This consolidation reduces the number of separate components and simplifies the overall interlock system while maintaining reliable beam securing through the unified structural design.
Solution Approach 2:
The locking pin mechanism is designed to be self-actuating or self-verifying, where the engagement and locking actions are inherent to the mechanism's operation. This self-service design reduces the need for additional control systems or complex actuation mechanisms, maintaining reliability while minimizing system complexity.

AI summary
Aspects of the present disclosure are directed toward apparatuses, systems, and methods for releasably connecting a first beam to a second beam. The apparatuses, systems, and methods may include a locking pin arranged on the first beam and configured to actuate between an unlocked position and a locked position and an arm coupled to the locking pin and extending parallel therewith. The apparatuses, systems, and methods may also include a sleeve arranged on the second beam and configured to receive the locking pin in the locked position to releasably secure the first beam to the second beam.
