Blade Element Actuated Lubrication Pump for Articulated Trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional greasing systems for articulated trucks with movable blade elements require frequent manual lubrication, disrupting workflow and operation, especially in environments where maintenance is challenging due to extensive wear and tear and dirt accumulation.
Innovation Solution
An automatic lubrication system where a mechanical pump connected to a lubricant reservoir is activated by the blade element's movement between positions, using an actuation element to dispense lubricant to lubrication points via flexible pressure hoses, eliminating the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual greasing is used to lubricate moving parts, then lubrication can be applied to lubrication points, but workflow is interrupted and operator intervention is required frequently
Solution Approach 1:
The lubrication system is designed to automatically service itself by using the blade element's own movement to activate the pump through the actuation element, eliminating the need for external operator intervention and enabling continuous operation without workflow interruption
Solution Approach 2:
The system performs lubrication automatically during the blade element's movement between positions, applying lubricant before wear and tear become critical problems, thereby maintaining reliability without requiring separate manual intervention steps
2Extent of automation
If electric pump with fixed lines is used to lubricate moving parts, then automated lubrication is achieved, but system complexity increases and adaptability to blade movement is reduced
Solution Approach 1:
The system replaces fixed rigid connections with flexible pressure hoses that can dynamically adapt to the blade element's movement between positions, maintaining automated lubrication while reducing system complexity and improving adaptability to changing configurations
Solution Approach 2:
The actuation element acts as an intermediary that converts the blade element's mechanical movement into pump activation, enabling automated lubrication through a simple mechanical coupling rather than complex electrical controls or fixed line systems
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
Ensures continuous operation by automatically lubricating moving parts as the blade element moves, reducing downtime and operator intervention, enhancing reliability and convenience while maintaining easy maintenance and adaptability.
Implementation Method 1
a pump (4) connected to a reservoir (8) of lubricant... dispense a displacement of a lubricant (8)... to feed the lubricant (8) to at least one lubrication point (10, 12, 14, 16, 18)
