Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposal vehicles face challenges in efficiently collecting and transporting waste with limited personnel and time, particularly in ensuring operational safety during container emptying, due to restricted visibility and reliance on costly and unreliable optical systems for monitoring.
Innovation Solution
Equipping disposal vehicles with a camera arrangement capable of creating three-dimensional spatial images and an image evaluation unit for automatic volume calculation and change detection, allowing for quick reaction to potential dangers without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional left-hand drive standard truck chassis is used, then cost is reduced and availability is improved, but driver visibility to the right is limited and operational safety is compromised
Solution Approach 1:
The patent replaces mechanical/optical monitoring systems (cameras, sensors, mirrors) with a driver wearing an augmented reality headset that provides virtual visual monitoring of the danger area. This substitution maintains safety functionality while allowing use of conventional left-hand drive chassis, resolving the contradiction between cost/chassis availability and operational safety.
2Loss of information
If optical systems such as cameras and sensors are used for monitoring, then visibility of the danger area is improved, but system complexity increases and reliability decreases due to environmental interference
Solution Approach 1:
The patent extracts the monitoring function from complex external optical systems and relocates it to a simplified wearable device (augmented reality headset) on the driver. This extraction eliminates the need for multiple cameras, sensors, and processing units while maintaining comprehensive danger area visibility, thus reducing system complexity.
Solution Approach 2:
The driver themselves performs the monitoring function through the augmented reality headset, eliminating the need for separate automated optical monitoring systems. The driver's own sensory capabilities are enhanced rather than replaced by complex machinery, simplifying the overall system.
3Area of stationary object
If multiple sensors are arranged side by side to monitor the danger area, then coverage area is improved, but device complexity and cost increase
Solution Approach 1:
The augmented reality headset serves multiple functions simultaneously: it provides virtual visual monitoring of the danger area, displays alerts and warnings, and guides the driver's attention. This single multi-functional device replaces what would otherwise require multiple specialized sensors and processing systems, reducing complexity while maintaining comprehensive monitoring coverage.

AI summary
A waste disposal vehicle (1) with at least one vehicle-mounted receiving container (2) for residual materials, recyclables or the like and with at least one feeding device (3) for receiving and transferring goods to be disposed of to the receiving container (2) is designed such that the waste disposal vehicle (1) is equipped with at least one monitoring camera arrangement (15; 16; 17; 18; 19) that creates three-dimensional spatial images and with an image evaluation unit, from which a volume calculation of a space (21;22;23;24a;24b) recorded by the camera arrangement (15; 16; 17; 18; 19) can be carried out and any change in volume that may occur when an object enters this space (21;22;23;24a;24b) can be recorded.
