Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hose retention systems for drilling machines are inadequate in preventing hoses from coming out during high velocity winds or turbulent operating conditions, leading to potential rupture and damage to machine components, resulting in increased downtime and maintenance costs.
Innovation Solution
A hose retention system comprising a bracket assembly with a central opening and a movable gate that can be locked in place using gate locking pins, allowing the hoses to be securely enclosed on all sides and preventing them from oscillating or coming out during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hose cage is provided to limit the movement of the hoses, then the hose movement is restricted, but the hoses can still come out of the hose cage from an open side during high velocity winds and turbulent operating conditions
Solution Approach 1:
The hose cage is divided into multiple sections with individual gates that can be independently controlled. Each gate can be opened or closed based on the operational requirements, allowing the hose to be contained when needed while maintaining accessibility when required. This segmentation enables reliable hose containment during high velocity winds and turbulent conditions.
Solution Approach 2:
The hose cage incorporates movable gates that can dynamically adjust their position between open and closed states. The gates are coupled to actuators that respond to operational signals, allowing the hose cage to adapt its containment capability based on wind conditions and operational requirements. This dynamic adjustment ensures reliable hose containment while maintaining operational flexibility.
2Device complexity
If the hose cage encloses the hoses only on three sides, then the structure is simpler, but the hoses may engage with mast weldment or other components of the machine causing rupture
Solution Approach 1:
The hose cage is segmented into multiple sections with individual gates, allowing each section to be independently controlled. This segmentation enables the hose cage to provide comprehensive enclosure on all sides when needed, preventing hose engagement with mast weldment and other machine components, while maintaining structural simplicity through modular design.
Solution Approach 2:
The movable gates act as intermediary elements between the hose and the machine components. When closed, the gates create a protective barrier that prevents direct contact between the hose and potential damage sources such as mast weldment. This intermediary mechanism provides comprehensive protection while maintaining a relatively simple overall structure.
3Reliability
If the gate is made movable to allow hose passage, then the hose can be securely enclosed, but the device complexity increases due to locking mechanisms
Solution Approach 1:
The gate locking mechanism is designed to be self-actuating through the coupling of the gate to the actuator. The operational signals that control the gate opening are automatically used to control the locking pin position, eliminating the need for separate complex locking control systems. This self-service approach maintains reliability while minimizing additional complexity.
Solution Approach 2:
The actuator serves multiple functions: it controls both the gate opening/closing and the locking pin position. This multi-functionality reduces the need for separate control mechanisms, thereby maintaining reliable hose enclosure while minimizing the overall device complexity associated with locking mechanisms.

AI summary
A hose retention system for a machine includes a bracket assembly defining a central opening. The hose retention system also includes a gate coupled to the bracket assembly and being movable between a closed position and an open position. The gate is disposed in the open position to allow passage of one or more hoses of the machine through the central opening of the bracket assembly. The gate is movable in any one of a clockwise direction and an anti-clockwise direction. The hose retention system includes at least one gate locking pin coupled to the bracket assembly that is movable between a locked state to prevent a movement of the gate to the open position and an unlocked state. In the unlocked state, the at least one gate locking pin allows a movement of the gate to the open position.
