Telehandler Quick Coupling With Oblique Crosspieces for Clearer Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick couplings on telescopic handlers obstruct the operator's view, making it difficult to correctly position accessories like forks relative to a load, necessitating inconvenient maneuvers to compensate for limited visibility.
Innovation Solution
The quick coupling design features oblique inner sides on its crosspieces, allowing unobstructed visibility by creating free passages for the operator's view, enhancing the visibility of the accessory's position relative to the load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the crosspieces are made with a substantial cross-section to support heavy loads, then the load-bearing capacity is improved, but the operator's visibility is reduced
Solution Approach 1:
The crosspieces transition from a conventional horizontal orientation to an oblique orientation, angled downward from front to rear. This dimensional change in orientation allows the operator's line of sight to pass underneath the crosspieces, effectively removing the visibility obstruction while preserving the structural strength and load-bearing capacity of the substantial cross-section.
2Object-affected harmful factors
If the crosspieces are made slim to improve visibility, then the operator's view is improved, but the structural strength is reduced
Solution Approach 1:
Rather than reducing the cross-sectional dimensions of the crosspieces, the invention changes their spatial orientation to an oblique configuration. This allows the full structural strength of the substantial cross-section to be maintained while the downward angle creates clear visibility passages for the operator.
3Object-affected harmful factors
If the operator performs preparatory maneuvers to improve viewing angles, then the visibility of accessory position is improved, but the operational complexity and time required are increased
Solution Approach 1:
The invention extracts and removes the visibility obstruction caused by the crosspieces through oblique positioning. This eliminates the need for the operator to perform additional preparatory maneuvers, allowing direct viewing of the accessory position and load alignment, thereby reducing operational complexity and time requirements.
