Waste Container Cleaning Device Side Chamber Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste container emptying vehicles face challenges in accessing and maintaining technical system components due to limited space, requiring the device to be removed for maintenance, which is laborious and time-consuming.
Innovation Solution
The vehicle design includes a trough that narrows by at least 50 cm from its upper side to its underside, creating side space for a chamber to house technical system components, making them readily accessible without disconnection of hydraulic and electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If technical system components are placed on the front side of the device, then all components can be accommodated in limited space, but access to components becomes difficult and maintenance requires device removal
Solution Approach 1:
The patent transitions from placing components on the front side (2D surface arrangement) to utilizing the side space created by the tapered trough (3D spatial rearrangement). The trough narrows from upper side to underside by at least 50 cm, creating a chamber on the side of the device that accommodates all technical system components, thereby providing both adequate space and easy side access without requiring device removal.
2Ease of repair
If device is removed from vehicle for maintenance, then components can be accessed, but hydraulic and electrical connections must be disconnected which is laborious and time-consuming
Solution Approach 1:
The patent segments the device into functionally independent modules: the trough assembly for waste handling and the chamber assembly for housing technical components. This segmentation allows the chamber with its components to be independently accessible from the side, enabling maintenance of hydraulic and electrical components without removing the entire device from the vehicle or disconnecting connections.
3Device complexity
If trough maintains uniform width, then structural simplicity is maintained, but no space is created for chamber housing components
Solution Approach 1:
The patent introduces asymmetry in the trough design by narrowing it from the upper side to the underside on one side by at least 50 cm, while maintaining functional integrity. This asymmetric tapering creates the chamber space needed for housing technical components without significantly complicating the overall trough structure, as the narrowing is concentrated in a specific region rather than requiring complete structural redesign.
