Load-Handling Device Pneumatic Nozzle Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for loading and unloading wood material, such as logs and pulpwood, often result in waste like sand, snow, or twigs becoming loose and scattered on the transport vehicle, making cleaning laborious and inefficient, with existing solutions not effectively addressing the need to clear waste from the top of loaded vehicles.
Innovation Solution
A load-handling device equipped with a nozzle connected to a pressure source for delivering pressurized air, which is used to clean the vehicle's load space and structures by spraying air to dislodge and remove waste before the vehicle starts, utilizing a boom and control device to maneuver the spray effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning by brushing is used, then the load space can be cleaned, but the process is laborious and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical brushing system with a pneumatic system that uses compressed air delivered through hoses and nozzles to clean the load space and wood material, eliminating the need for manual brushing while significantly increasing cleaning speed and efficiency
Solution Approach 2:
The invention employs compressed air (pneumatics) as the cleaning medium, using hoses to transport the air and nozzles to deliver high-velocity air streams that effectively remove waste and contaminants from the load space and wood material surfaces without manual intervention
2Ease of operation
If manual cleaning is performed, then waste can be removed, but the risk of stumbling or slipping increases
Solution Approach 1:
The patent replaces manual cleaning operations with an automated pneumatic cleaning system, eliminating the need for operators to physically enter the load space or approach the wood material, thereby removing the risk of stumbling or slipping entirely
Solution Approach 2:
The pneumatic cleaning system performs the cleaning function autonomously without requiring operator presence in the hazardous area, allowing the system to clean itself and the load space without human intervention in the dangerous zone
3Ease of manufacture
If the bottom structures are not designed for cleaning, then manufacturing is simpler, but cleaning effectiveness is poor
Solution Approach 1:
The patent segments the cleaning function from the structural design by introducing separate, movable cleaning components (hoses and nozzles) that can be positioned and directed as needed, rather than requiring the entire bottom structure to be designed with built-in cleaning features
Solution Approach 2:
The cleaning system uses flexible hoses and movable nozzles that can be dynamically positioned and directed to reach different areas of the load space and wood material, providing effective cleaning without requiring complex built-in structural cleaning features
4Device complexity
If no cleaning system is used, then device complexity is reduced, but waste remains on the vehicle
Solution Approach 1:
The pneumatic cleaning system serves multiple functions: it cleans the load space bottom structures, cleans the wood material surfaces, removes waste from the vehicle, and can be integrated with the existing compressed air supply system of the vehicle, providing comprehensive cleaning capability without requiring entirely separate 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
This method allows for efficient and safe removal of waste from the vehicle's load space and structures without the need for manual cleaning, significantly reducing time and increasing safety, with the added benefit of being able to clear waste from the top of loaded vehicles, thus enhancing operational efficiency and cost-effectiveness.
