Stacker Crane Upper Frame Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stacker cranes face challenges in manufacturing complexity and insufficient connecting strength between the upper frame and support rods, leading to potential deformation and inadequate movement restriction of the support rods.
Innovation Solution
The stacker crane design incorporates a main plate elongated vertically with mast connecting portions and a reinforcing plate elongated horizontally, which are bolted to the support rods, providing sufficient tension and bending strength to prevent rod separation and deformation, while also allowing for easy manufacturing by integrating the reinforcing part into the main frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the upper frame is constructed with multiple connecting plates and bolts to connect support rods, then the connecting strength between upper frame and support rods is improved, but the manufacturing complexity and assembly complexity increase
Solution Approach 1:
The patent merges multiple connecting plates into a single integrated upper frame structure. The upper frame is designed as one piece with built-in connection features that directly engage the support rods, eliminating the need for separate connecting plates and multiple bolts. This integration maintains the necessary connecting strength while significantly reducing manufacturing complexity and assembly steps.
Solution Approach 2:
The upper frame is designed to perform multiple functions simultaneously: it provides structural support, connects support rods, and incorporates guiding features for the platform. By integrating these functions into a single component, the patent reduces the number of parts needed while maintaining or improving overall system strength and reliability.
2Ease of manufacture
If the upper frame uses a simple structure with fewer components, then the manufacturing process is simplified, but the connecting strength and stability between upper frame and support rods deteriorate
Solution Approach 1:
The patent combines multiple structural functions into the upper frame's integrated design, eliminating the need for separate reinforcing plates and multiple connection components. This merging approach simplifies manufacturing while the strategic design of the integrated connection features ensures adequate connecting strength and stability.
3Ease of operation
If the support rods are allowed to fluctuate freely, then the ease of assembly is improved, but the deformation of the rectangular frame structure increases
Solution Approach 1:
The patent integrates guiding features directly into the upper frame structure, combining the support and alignment functions into the main frame component. This integration provides stable positioning of support rods while maintaining straightforward assembly, as the guiding features automatically align components during assembly without requiring separate adjustment mechanisms.

AI summary
A stacker crane has an upper frame, which connects upper portions of front and rear support rods standing from both front and rear end portions of a lower frame, respectively, is connected to the front and rear support rods by bolts. The upper frame includes a main part comprising a first plate following along a vertical direction and having front and rear extensions being extended in the front and rear directions of the crane and mast connecting portions being extended downward from both the front and rear ends of the front and rear extensions. The upper frame has a reinforcing part comprising a second plate following along a horizontal direction projecting from the main part in a width direction and being extended in the front and rear directions. The mast connecting portions of the main part are urged against the side surfaces of the front and rear support rods, respectively.
