Compactor Hose Routing via Smooth Curved Passageways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydraulic hose routing in compactors obstructs visibility of the drum surfaces, leading to increased labor costs and potential leaks due to the use of multiple fittings required for hose passage through the compactor frame.
Innovation Solution
A routing method that uses elongate steel plates and extension plates to create a continuous passageway for hydraulic hoses from the drum to the interior space, minimizing the need for bulkheads and sharp bends, allowing for improved visibility and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic hoses are routed through the compactor frame using multiple fittings and bulkheads, then the hoses can pass through the frame structure, but the visibility of drum surfaces is obstructed and the complexity of the routing system increases
Solution Approach 1:
The patent extracts the hose routing function from the complex fitting system and relocates it to a simplified support structure. The support with integrated opening eliminates the need for multiple bulkheads and fittings, directly resolving the contradiction by removing unnecessary components while maintaining reliable hose passage.
Solution Approach 2:
The support structure serves multiple functions: it provides structural connection between the drum and frame, creates a hose passage way, and eliminates the need for separate bulkheads and fittings. This multi-functionality reduces overall system complexity while maintaining routing reliability.
2Reliability
If multiple fittings are used for hose passage, then the hoses can be properly connected, but labor costs for installation and maintenance increase
Solution Approach 1:
The patent merges the functions of multiple separate fittings and bulkheads into a single integrated support structure. This consolidation reduces the number of connection points, thereby reducing labor costs for installation and maintenance while maintaining reliable hydraulic connections.
3Adaptability or versatility
If sharp bends and 90-degree fittings are used for hose routing, then the hoses can make sharper turns, but the hoses experience increased wear and the routing becomes more complex
Solution Approach 1:
The patent employs smooth curved transitions instead of sharp bends and 90-degree fittings in the hose routing path. This curvature approach allows the hose to make necessary turns while minimizing stress concentration and wear, directly addressing the contradiction between routing flexibility and hose durability.
4Device complexity
If hydraulic hoses are routed close to the drum surface, then the routing is compact, but the visibility of the drum surface is blocked
Solution Approach 1:
The patent routes the hydraulic hoses through a dedicated opening in the support structure, moving the hose path to a different spatial dimension relative to the drum surface. This dimensional separation allows compact routing while maintaining clear visibility of the drum surface from the operator's position.

AI summary
A compactor with a hose routing includes a drum connected to a frame with a support. The frame defines an interior space of the compactor and includes a plate through which an opening extends to the interior space. A hose assembly extends from an end of the drum through the opening to the interior space without the use of bulkheads.
