Self-Cleaning Side Loading Garbage Truck Packer Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Side loading garbage trucks often leave behind uncollected garbage, requiring operators to manually enter the truck to remove missed waste, necessitating a side door and floor clean-out trough for access and removal.
Innovation Solution
A side loading trash truck design featuring a two-piece self-cleaning packer blade with a vertical top portion and retractable horizontal bottom portion that initially packs and then compacts garbage, eliminating the need for operator entry and side door access by ensuring complete collection and ejection without escape during transport and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional packing blade is used to push garbage through the hopper, then garbage collection is achieved, but some garbage is left behind requiring manual removal
Solution Approach 1:
The packing blade is divided into two separate components: a fixed vertical top blade and a movable horizontal bottom blade. This segmentation allows each blade to perform specialized functions - the top blade maintains separation between hopper and body while the bottom blade performs compacting and ejection, eliminating garbage left behind and removing the need for manual cleaning operations.
Solution Approach 2:
The bottom blade is designed to be movable between horizontal and vertical positions through hydraulic actuation. During normal operation, it moves horizontally to compact garbage. During ejection, it rotates to a vertical position to allow complete discharge. This dynamic positioning ensures complete garbage collection without requiring operator entry into the body.
2Ease of operation
If a side door and floor clean-out trough are added for manual garbage removal, then missed garbage can be removed, but device complexity and operational safety risks increase
Solution Approach 1:
The dual-blade system performs self-cleaning functionality automatically. The bottom blade's horizontal movement during compacting and its vertical rotation during ejection automatically removes all garbage from the body without requiring operator entry or separate clean-out mechanisms. The system serves itself by ensuring complete garbage discharge through the rear door.
3Quantity of substance
If garbage is compacted in the body, then space utilization improves, but garbage may escape during transport
Solution Approach 1:
The top blade maintains a fixed vertical position that creates a localized separation between the hopper and body compartments. This local structural feature prevents garbage from escaping during transport while still allowing the bottom blade to move freely for compacting operations. The fixed top blade acts as a barrier that maintains containment integrity.

AI summary
A side 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.
