Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automated storage and retrieval systems, accurately aligning the rail system above the framework structure is challenging, especially when retrofitting access stations, as it requires precise cutting of upright members and can lead to sagging or misalignment of port frames over time.
Innovation Solution
The implementation of a framework adjuster using a double-threaded rod with a first threaded section engaged in the first framework element and a second threaded section engaged in the second framework element, allowing for adjustable distance control between these elements by rotating the rod, thereby ensuring horizontal alignment of the rail system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If precise cutting of upright members is performed to align the rail system, then the horizontal alignment of the rail system is improved, but the complexity and time required for installation increases
Solution Approach 1:
The framework adjuster enables dynamic adjustment of framework element positions after installation. The threaded rod mechanism allows operators to move framework elements horizontally and vertically to achieve proper alignment, eliminating the need for precise pre-cutting and complex installation procedures.
Solution Approach 2:
The adjuster changes the positional parameters of framework elements through threaded rod rotation. By converting rotational motion into linear displacement, the system allows precise control of framework element positions, achieving horizontal alignment without complex cutting operations.
2Manufacturing precision
If precise cutting of upright members is performed to align the rail system, then the horizontal alignment of the rail system is improved, but the installation time increases
Solution Approach 1:
The adjuster provides post-installation adjustment capability, allowing framework elements to be positioned correctly after initial installation. This eliminates time-consuming precise cutting operations and enables quick installation followed by simple adjustment procedures.
Solution Approach 2:
Framework elements can be installed in their rough positions without precise cutting first. The adjuster then performs the alignment function afterward, separating the installation and alignment operations to reduce overall installation time.
3Stability of the object's composition
If fixed framework elements are used, then the structural stability is improved, but the ability to correct misalignment and prevent sagging worsens
Solution Approach 1:
The adjuster transforms fixed framework elements into dynamically adjustable ones. The threaded rod mechanism provides controlled movement capability while maintaining structural integrity, allowing correction of misalignment and prevention of sagging without compromising overall stability.
Solution Approach 2:
The adjuster enables iterative adjustment and verification of framework element positions. Operators can make adjustments, check alignment, and refine positions as needed, ensuring proper horizontal alignment and preventing future misalignment issues.
4Adaptability or versatility
If adjustable mechanism is added to framework elements, then the ability to correct misalignment is improved, but the device complexity increases
Solution Approach 1:
The threaded rod acts as an intermediary mechanism between fixed framework elements. It provides the adjustment function without requiring complex integrated systems, using a simple yet effective screw mechanism to translate rotational input into linear positional adjustment.
