Tippable Container with Telescopic Arms for Symmetrical Emptying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted material collecting containers, such as those in suction excavators, face limitations in flexible emptying, as they can only tilt to one side and require complex, costly structures that result in incomplete emptying and contamination of the vehicle chassis with bulk material.
Innovation Solution
A vehicle design featuring a symmetrical material collecting container with a tilting axis parallel to its longitudinal axis, allowing independent control of lifting and tilting movements, and equipped with telescopic arms that can rotate and pivot to enable emptying on both sides, eliminating the need for manual adjustments and preventing chassis contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the container is tilted to one side only, then the structure is simple, but the emptying flexibility is limited and the vehicle must be moved or material tipped into a lower area
Solution Approach 1:
The tipping structure is segmented into two independent telescopic arms that can be controlled separately, allowing the container to be tilted to either side independently. This segmentation enables flexible emptying on both sides without requiring complex multi-axis mechanisms.
Solution Approach 2:
The telescopic arms provide dynamic positioning capability, allowing the tilting axis to be moved to different locations relative to the vehicle. This dynamic adjustment enables the system to adapt to different emptying scenarios while maintaining a relatively simple structural base.
2Ease of operation
If the tilting axis is arranged close to the outer edge of the vehicle frame, then the load can be tipped right next to the vehicle, but the vehicle chassis is contaminated by bulk material
Solution Approach 1:
The solution moves the tilting operation from a horizontal plane near the vehicle edge to a vertical dimension by extending the telescopic arms upward. This dimensional change allows the container to be tilted at height, directing material away from the chassis while maintaining ease of operation.
Solution Approach 2:
The telescopic arms act as intermediaries between the container and the vehicle frame, enabling the tilting axis to be positioned at a distance from the chassis. This intermediary mechanism prevents direct contact between spilled material and the vehicle frame.
3Adaptability or versatility
If a complex hydraulic system with multiple drives is used to tilt the container, then the tilting capability is enhanced, but the structure becomes complicated, expensive, and requires maintenance
Solution Approach 1:
The telescopic arms serve multiple functions: they support the container, provide the tilting mechanism, enable lateral movement, and allow height adjustment. This multi-functionality achieves enhanced tilting capability while avoiding the need for separate hydraulic systems for each function.
Solution Approach 2:
The design uses two identical telescopic arms that can be controlled independently, providing symmetrical tilting capability to both sides. This copying approach simplifies the overall system design compared to asymmetric multi-drive solutions while maintaining full tilting versatility.
4Productivity
If the container is tilted at a lower position, then the tilting structure is simpler, but the material falls immediately next to the vehicle and complete emptying is difficult
Solution Approach 1:
The solution elevates the tilting operation to a higher vertical dimension using extendable telescopic arms. This height increase allows material to be deposited farther from the vehicle, achieving more complete emptying while maintaining structural efficiency through the telescopic mechanism.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and complete emptying of the container on both sides, with the tilting axis positioned outside the vehicle base, preventing chassis contamination and allowing for higher tilting heights, thus enhancing operational flexibility and reducing maintenance costs.
Implementation Method 1

AI summary
The invention relates to a vehicle (01) comprising a tippable material collection container (05) which is suspended along a tipping axis (07) extending parallel to the longitudinal axis (04a) of the vehicle, and a telescoping device. The tipping axis (07) extends in the plane of symmetry of the material collection container. The base-side ends of the telescope arms (09) are fixed in the central plane (04) of the vehicle in a pivotably movable manner. At least one rotary drive (16) is arranged on the container-side end of at least one telescope arm (09) in order to allow a rotation of the material collection container (05) about the tipping axis (07). At least one pivoting drive (13) allows pivoting of the telescope arm (09) from the central plane (04) of the vehicle in the two angular directions. Fig. 2
