Integrally Formed Pocket Frame for Dump Deck Cylinder Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frame type dump decks for dump trucks are heavy, expensive, and have complex structures, which increase their cost and weight, while also being prone to damage due to stress concentration and fatigue from multiple welding points, limiting their durability and manufacturing efficiency.
Innovation Solution
A frame type dump deck design that integrates an eye end cylinder with improved pocket structures, featuring integrally formed pocket frames and reinforcement members that reduce the need for additional welding and reinforcement patches, enhancing structural stiffness and durability while simplifying manufacturing and reducing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a frame type deck with outer cover cylinder is used, then torsional stiffness and adjustment stability are improved, but structure becomes complicated, weight increases, and cost increases
Solution Approach 1:
The patent merges the frame type deck structure with the eye end cylinder mounting system. The pocket structure is integrally formed with the deck frame, and the eye end cylinder is directly mounted on the pocket top without requiring separate outer cover components. This integration maintains the torsional stiffness of frame type decks while eliminating the structural complexity and additional weight of outer cover cylinders.
2Reliability
If reinforcement materials are added to the pocket top, then damage probability is reduced, but manufacturing complexity increases and production time increases
Solution Approach 1:
The pocket structure is designed with pre-reinforced geometry during the initial forming process. The pocket top is integrally formed with strengthened structural features that inherently resist damage without requiring subsequent reinforcement patches or additional welding operations. This preliminary design approach ensures damage resistance while maintaining manufacturing efficiency.
3Strength
If multiple welding portions are used for reinforcement, then structural strength is improved, but fatigue damage probability increases
Solution Approach 1:
The patent applies local quality optimization by strategically positioning welding portions only where structurally necessary. The pocket frame and reinforcement members are designed to concentrate welding at critical load-bearing joints while minimizing welding in non-critical areas. This selective welding approach maintains structural strength while reducing the overall number of welding portions and associated fatigue risks.

AI summary
A frame type dump deck for a dump truck includes a front panel having a pocket formed in a center portion of the front panel having side wall panels which extend perpendicularly from an interior face of the center portion. Two side panels attached to opposing ends of the interior face of the front panel extend in a deck length direction. A floor panel has floor frames arranged in two parallel rows which extend in the deck length direction and terminate at the front panel. Pocket frames extend from the terminal ends of the floor frames in parallel along each edge of the pocket, and include top portions connected via a pocket reinforcement member. The pocket frames are integrally formed on an outside face of the front panel so that an eye end cylinder may be connected to a cylinder hinge above the pocket.
