Baler Wrap Roll Hanger With Center-of-Gravity Self-Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The hanger for loading a roll of wrap material into a baler implement is positioned at a height that is difficult for users to reach, making it challenging to attach and detach, as seen in existing lifting devices.
Innovation Solution
A lift system with a hanger body having a center of gravity positioned within an aperture, secured by a lift line that applies a lift force at the center of gravity, allowing the hanger to rest flat against the structure for secure storage without manual reattachment or detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the hanger is stored at a high position on the baler implement structure, then storage space utilization is improved, but the ease of operation deteriorates because users cannot easily reach the hanger to attach or detach it
Solution Approach 1:
The hanger is designed with a center of gravity positioned within its body such that when the lift line applies upward force, the hanger automatically orients itself and rests flat against the high storage position on the baler implement structure. This self-orienting mechanism eliminates the need for manual positioning or reattachment by the user, allowing the hanger to service itself at the elevated storage location.
2Ease of operation
If the hanger is positioned at ground level for easy access, then ease of operation is improved, but the reliability deteriorates because the hanger cannot remain stationary without manual reattachment
Solution Approach 1:
The hanger's center of gravity is positioned within its body to create a stable equilibrium state when the lift line applies upward force. This gravitational equipotential design ensures that once the hanger reaches its storage position on the baler implement structure, it naturally orients itself flat against the structure and remains stationary without requiring additional manual attachment or intervention, thereby maintaining reliability at elevated positions.
3Device complexity
If the lift line applies force at a point other than the center of gravity, then the lifting mechanism is simplified, but the ease of operation worsens because the hanger does not rest flat against the structure for secure storage
Solution Approach 1:
The lift line serves multiple functions simultaneously: it provides the lifting force to raise the hanger to the storage position, and by applying force at the center of gravity, it also ensures the hanger orients itself correctly to rest flat against the baler implement structure. This multi-functionality eliminates the need for separate positioning or securing mechanisms, simplifying the overall system while ensuring secure storage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The lift system enables easy and secure storage of the hanger, eliminating the need for manual reattachment or detachment, and ensures the hanger remains stationary in the storage position.
Implementation Method 1
The first aperture is positioned such that a center of gravity of the hanger body is located within the first aperture. The lower end portion of the lift line passes through the first aperture such that the lift line applies a lift force to the hanger body at the center of gravity of the hanger body.

AI summary
The present invention relates to a lift system (30) for a baler implement, the lift system including a hanger (38) including a hanger body (42) defining a first aperture (60). The first aperture is positioned such that a center of gravity (62) of the hanger body is located within the first aperture. A lift line (36) includes an upper end portion (66) secured to a line actuator (34), and a lower end portion (68) supporting the hanger. The lower end portion of the lift line is secured relative to the hanger such that the lift line applies a lift force to the hanger body at the center of gravity of the hanger body. This allows the hanger to be drawn up snugly, such that the hanger is conveniently stored tight against the lift structure (40).
