Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for picking up and transporting loads on industrial trucks face challenges in adjusting load width and maintaining stability, maneuverability, and visibility for the driver, particularly due to complex guidance systems and increased dead weight that reduce loading capacity.
Innovation Solution
A device with horizontally movable sliding arms and a common guide rail allows for parallel movement of load-carrying elements via hydraulic or electric drives, enabling adjustment of load width without increasing the device's depth or height, maintaining maneuverability and minimizing obstruction for the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate guide is used for parallel movement of load-carrying elements, then the stability and positioning accuracy are improved, but the device depth increases and driver visibility is blocked
Solution Approach 1:
The patent combines the guidance function for parallel movement into the existing guide structure of the load-carrying elements. The guide that originally only enabled width adjustment now also provides guidance for parallel movement, eliminating the need for a separate guide structure and maintaining driver visibility while achieving stable and accurate positioning.
Solution Approach 2:
The existing guide structure is designed to serve multiple functions: it guides the load-carrying elements during width adjustment and simultaneously provides guidance during parallel movement. This multi-functional design avoids increasing device depth while maintaining positioning accuracy and stability.
2Adaptability or versatility
If the guide and drive elements are designed for loaded adjustment, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The guide and drive elements are designed with dynamic characteristics that allow them to accommodate both loaded and unloaded conditions. The hydraulic drive system maintains pressure and control throughout the adjustment range, enabling smooth operation whether the forks are loaded or empty, without requiring fundamentally different structural designs.
3Ease of manufacture
If two separate drive elements are used for width adjustment, then the manufacturing simplicity is improved, but the stability is reduced due to excessive lateral displacement
Solution Approach 1:
The system performs width adjustment before the parallel movement operation. By pre-positioning the load-carrying elements at the correct width while the vehicle is still stable, the subsequent parallel movement occurs with minimal lateral displacement, maintaining vehicle stability throughout the operation.
