Solution Overview
Problem
Existing wrapping technologies face challenges in depositing rotated and wrapped objects on the ground without damaging the wrap, often requiring tilting mechanisms that depend on traveling velocity and object dimensions, which can be mechanically stressful and inefficient.
Innovation Solution
A wrapping apparatus with an object supporting device and rotating device that maintains a controlled rotational velocity synchronized with the traveling velocity, allowing the wrapped object to be deposited while the apparatus is in motion, reducing relative movement and mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wrapping apparatus stops to deposit the wrapped object on the ground, then the wrap is less likely to be damaged, but the productivity decreases due to interruption of continuous operation
Solution Approach 1:
The patent applies dynamics by making the wrapping apparatus movable rather than stationary. The entire wrapping apparatus moves over the ground and deposits the wrapped object during motion, eliminating the need to stop for deposition. This dynamic approach maintains wrapping continuity while managing the deposition process during movement, resolving the contradiction between continuous operation and safe deposition.
Solution Approach 2:
The patent implements continuity of useful action by enabling the wrapping apparatus to deposit wrapped objects without stopping. The apparatus maintains its traveling motion throughout the wrapping and deposition process, allowing continuous wrapping operations without interruptions. This ensures uninterrupted productive action while completing the deposition function.
2Productivity
If the wrapping apparatus moves while depositing the wrapped object, then the productivity increases, but the wrap may be damaged due to relative movement and impact with the ground
Solution Approach 1:
The patent applies preliminary action by rotating the wrapped object at a controlled velocity before deposition. The rotational velocity is synchronized with the traveling velocity of the apparatus, preparing the object for soft deposition. This preliminary rotational synchronization ensures that the object's surface velocity matches the apparatus's forward velocity, enabling gentle contact with the ground during motion without wrap damage.
Solution Approach 2:
The patent implements parameter changes by adjusting the rotational velocity of the wrapped object based on the traveling velocity of the apparatus. The rotational parameter is dynamically changed to match the forward motion speed, creating a coordinated motion state. This parameter synchronization allows the object to be deposited during movement while maintaining wrap integrity through controlled relative motion.
3Ease of operation
If a tilting mechanism is used to deposit the wrapped object, then the deposition can be controlled, but the device complexity increases and mechanical stress is introduced
Solution Approach 1:
The patent applies the taking out principle by removing the tilting mechanism from the system. Instead of using a complex tilting apparatus to control deposition, the invention uses the natural combination of the apparatus's forward motion and the object's rotational velocity. The deposition control is achieved through velocity synchronization rather than mechanical tilting, extracting the unnecessary complex component while maintaining operational control.
Solution Approach 2:
The patent implements mechanics substitution by replacing the mechanical tilting system with a velocity-based control system. Instead of using mechanical angles and physical tilting to control deposition, the invention uses synchronized rotational velocity matched to traveling velocity. This substitutes a complex mechanical tilting system with a simpler velocity coordination approach, reducing device complexity while maintaining deposition control.

Function Achieved in This Case
This approach enables continuous operation of the wrapping process, reduces the risk of wrap damage, conserves wrapping material, and increases throughput by allowing uninterrupted movement of the wrapping apparatus, thus enhancing efficiency and reducing mechanical stress.
Implementation Method 1
the object rotating device keeps or achieves a rotation of the object carried on the object supporting device at least before the object is removed from the object supporting device. While being carried on the object supporting device and being wrapped, the object is rotated with respect to the wrapping apparatus frame with a selected rotational velocity

AI summary
The invention refers to a movable apparatus (3) and method for wrapping an object (B) and for depositing the wrapped object on the ground. The wrapping apparatus is moved over ground in a travelling direction (TD) with a travelling velocity (v). The object is placed onto an object supporting device (15). An object rotating device (10.f, 10.r) rotates the object being carried by the object supporting device. Thereby the carried and rotated object (B) is wrapped into a web of wrapping material. This web is taken from a reservoir (22) held by a reservoir holder. The wrapped object is placed on the ground. The rotational velocity (ω_B) with which the object on the object supporting device is rotated depends on the travelling velocity (v) of the wrapping apparatus. Thereby the risk is reduced that the wrap around the object is damaged when placing the object on the ground.
