Frangible Tab Control System for Dump Link Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dump truck systems with tilt and dump links face issues when improperly operated, as they can apply large forces that may damage the dump link, and existing solutions do not adequately prevent damage while ensuring safe operation.
Innovation Solution
A control system featuring a tab pivotally connected to a structure via a coupling member, with a frangible member holding the tab in place, which breaks under excessive force, allowing the tab to pivot and prevent damage to the dump link by disabling the external system when a large force is applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a frangible member is used to hold the tilt tab in place, then damage to the dump link is reduced, but the system cannot detect or control excessive force application
Solution Approach 1:
The patent incorporates a sensor that detects the position of the tilt tab and provides feedback to a control system. When the tilt tab moves beyond a predetermined position indicating excessive force, the sensor triggers an alarm or shuts down the hydraulic system, preventing damage while providing active monitoring and control feedback.
Solution Approach 2:
The patent introduces a control system as an intermediary between the mechanical components and the operator. This intermediary monitors system parameters, detects abnormal conditions through sensors, and automatically responds by controlling hydraulic valve operation or activating alarms, bridging the gap between mechanical force application and system protection.
2Object-affected harmful factors
If the tilt tab is allowed to pivot freely to prevent damage, then the dump link is protected, but the device cannot control external systems under excessive force conditions
Solution Approach 1:
The patent employs dynamic control where the system's behavior changes based on operating conditions. During normal operation, the tilt tab functions freely to control the dump link. When excessive force is detected through sensor feedback, the control system dynamically adjusts by shutting down hydraulic functions or activating alarms, allowing the system to adapt its control capability based on the operational state.
Solution Approach 2:
The control system automatically monitors and protects itself by detecting when the tilt tab indicates excessive force and automatically shutting down hydraulic functions or activating alarms without requiring external intervention, enabling the system to self-regulate and prevent damage while maintaining control capability within safe operating parameters.
