Front Loading Garbage Truck Self-Cleaning Packer Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front loading garbage trucks face issues with missed garbage collection, requiring manual removal by operators and engine heat issues due to trapped exhaust under solid cab shields, which can lead to engine problems.
Innovation Solution
A front loading garbage truck design featuring a two-piece self-cleaning packer blade with a retractable bottom portion for efficient garbage collection and a ventilated cab shield to prevent engine heat buildup, eliminating the need for a side door and floor clean-out, and allowing exhaust airflow to prevent engine intake contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a solid cab shield is used to prevent debris from falling onto the cab, then protection from debris is improved, but engine heat buildup occurs due to trapped exhaust
Solution Approach 1:
The cab shield is designed with a porous or perforated structure that allows exhaust gases and heat to pass through while still blocking larger debris. This resolves the contradiction by enabling thermal ventilation through the shield material itself, preventing engine heat buildup while maintaining debris protection functionality.
2Device complexity
If a single hole is provided in the cab shield for exhaust, then exhaust passage is simplified, but heat trapped under the shield enters the engine air intake system causing engine problems
Solution Approach 1:
Instead of a single hole, the cab shield incorporates multiple apertures or a porous structure that distributes exhaust flow across the entire shield surface. This prevents localized heat buildup and ensures uniform thermal ventilation, eliminating the risk of hot exhaust entering the air intake system while maintaining structural simplicity.
3Productivity
If the packing blade pushes garbage in a single pass, then collection speed is improved, but missed garbage requires manual removal by operator
Solution Approach 1:
The packing blade is divided into multiple segments or sections that can independently move or adjust. This segmentation allows different portions of the blade to handle different areas of the truck body simultaneously, ensuring complete garbage collection in a single pass without leaving missed areas that would require manual intervention.
Solution Approach 2:
The packing blade incorporates dynamic movement capabilities, allowing it to adjust its position, angle, or speed during operation. This dynamic adjustment enables the blade to adapt to varying garbage distributions and truck body geometries, ensuring thorough collection efficiency without manual follow-up.
4Ease of operation
If side door and floor clean-out trough are added for manual garbage removal, then missed garbage can be removed, but device complexity and maintenance needs increase
Solution Approach 1:
The packing blade system is designed to be self-cleaning and self-adjusting, automatically handling missed garbage through its dynamic movement and segmentation capabilities. This eliminates the need for additional manual access features like side doors and clean-out troughs, reducing structural complexity and maintenance requirements while maintaining complete garbage collection.

AI summary
A front loading garbage truck with a unique packing blade that creates a self-cleaning garbage truck without the need for manual clean outs and construction for the accomplishment of same. The packing blade includes a top vertical portion that is in a fixed position and a second bottom vertical portion that is retractable into a horizontal position to allow for repeated pass-throughs to collect all debris prior to emptying the garbage from the truck. Additionally, a unique cab shield sits atop the cab portion that contains a plurality of holes on the sides and along the top sloping face to allow ventilation therethrough and prevent damage to the engine caused by excessive heat.
