Rod Fixer with Buckle Handle for Ship Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rod fixers for ship containers fail to provide stable fixation during rough maritime conditions, leading to disengagement and potential loss of containers, posing safety risks due to the lack of a secure fixing structure between the fixing member and the connecting rod.
Innovation Solution
A rod fixer design featuring a fixing member with a buckle handle and a connecting rod with locating blocks, where the buckle handle is used to lock the fixing member and connecting rod firmly together, utilizing a fastening element and torsion spring for stability, preventing rotation or movement even under ship sway.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only locating blocks are locked into locating slots without additional fixing structures, then the device complexity is reduced, but the reliability of the connection deteriorates under strong ship swing and container deformation
Solution Approach 1:
The fixing member is divided into multiple functional components: locating blocks for initial positioning, locating slots for engagement, and a buckle handle with fastening element for secure locking. This segmentation allows each component to perform its specific function while collectively providing reliable connection.
Solution Approach 2:
The locating blocks are预先 positioned on the connecting rod, and the locating slots are pre-formed on the fixing member. This preliminary arrangement enables quick initial engagement before the buckle handle is operated to secure the connection, reducing the time and complexity of the fixing operation.
2Ease of operation
If the fixing member and connecting rod are allowed to disengage during ship swing, then the ease of operation is improved, but the safety and stability deteriorate
Solution Approach 1:
The buckle handle is designed to be operable during assembly and disassembly but remains locked during operation. The fastening element engages with the locating block to prevent disengagement under dynamic ship swing conditions, while still allowing manual operation when needed.
Solution Approach 2:
The fastening element acts as an intermediary between the buckle handle and the locating block. It transfers and secures the connection force, preventing direct disengagement between the fixing member and connecting rod during ship swing while allowing controlled operation during assembly.
3Reliability
If a buckle handle with fastening element is added to lock the fixing member and connecting rod, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The buckle handle integrates multiple functions: it provides the fastening element for locking, incorporates a torsion spring for automatic engagement, and includes a locating block for positioning. This merging of functions into a single component achieves reliable connection without proportionally increasing overall device complexity.
Solution Approach 2:
The torsion spring in the buckle handle provides automatic engagement with the locating block, and the elastic bead automatically clamps the concave portion. This self-service mechanism reduces the need for additional complex locking mechanisms while maintaining high reliability.
4Manufacturing precision
If the via hole has unequal upper and lower apertures with a step face, then the manufacturing precision is improved for locating, but the ease of manufacture deteriorates
Solution Approach 1:
The via hole is designed with asymmetric aperture sizes at the upper and lower ends, creating a step face. This asymmetric geometry provides precise locating for the locating block while the step face facilitates one-way engagement, preventing reverse movement. The design balances locating precision with manufacturability by using a simple drilling and reaming process.
