Machine Linkage Bump Stops for Impact Stress Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine linkages fail to effectively isolate impact stresses from implements to the machine frame during operational transitions, leading to structural stress and potential damage.
Innovation Solution
A linkage system comprising a carriage, pivotable arm assemblies, and bump stops that contact the arms in the stowed state to isolate impact stress from the frame, transferring it onto the linkage, thereby mitigating structural stress on the machine frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the implement is moved to the stowed state without bump stops, then the linkage can achieve full movement range, but impact stress is transferred to the machine frame causing structural stress
Solution Approach 1:
The bump stops serve as intermediary elements positioned between the linkage arms and the machine frame. When the implement reaches the stowed state, the bump stops contact the arms to absorb and isolate the impact stress, preventing direct transfer to the frame while allowing the linkage to achieve its full movement range.
2Strength
If bump stops are added to isolate impact stress, then structural stress on the frame is reduced, but the device complexity increases
Solution Approach 1:
The bump stops are designed as simple, easily replaceable components that can be quickly installed and removed from the linkage. This allows the system to gain the protective function of impact isolation without permanently complicating the overall structure, as the bump stops can be easily maintained or replaced when worn.
3Object-affected harmful factors
If bump stops are installed on the linkage, then impact stress is localized to the linkage, but maintenance access becomes more difficult
Solution Approach 1:
The bump stops are designed as separate, modular components that can be independently accessed and replaced without disassembling the entire linkage system. This segmentation allows maintenance personnel to quickly remove and replace worn bump stops while leaving the rest of the linkage assembly intact, balancing stress localization with maintenance accessibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively isolates impact stress from the machine frame, reducing structural stress and prolonging the lifespan of machine components by localizing forces within the linkage, while also facilitating easier maintenance access.
Implementation Method 1
The bump stops are configured to contact an arm, of the arm assembly, in the stowed state of the implement to isolate impact stress away from the frame and onto the linkage

AI summary
A linkage for moving an implement between a working state and a stowed state with respect to a frame of a machine. The linkage includes a carriage, at least one arm assembly, and one or more bump stops. The carriage is configured to support the implement. The arm assembly is coupled to the carriage and is pivotable with respect to the carriage to move the implement to the stowed state. The bump stops are configured to contact an arm, of the arm assembly, in the stowed state of the implement to isolate impact stress away from the frame and onto the linkage.
