Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forage bale pick-up devices, particularly of the inclined plane type, face challenges such as significant wear and breakage due to the effort required to lift bales, rebound effects at high speeds, and loss of material due to friction, which can deform bales and break ropes.
Innovation Solution
A self-loading forage bale pick-up device with a folding chassis that rotates around a pivoting axis to maximize ground contact and includes a damper assembly to absorb impact energy, allowing for efficient and smooth bale lifting without slowing down the machine, featuring elastic damping elements and independent sub-chassis for enhanced traction and reduced stress on the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inclined plane type pick-up device is used to lift bales, then the bales can be transported to the loading platform, but the traction tines and drag chains experience significant wear and breakage due to the considerable effort required at height
Solution Approach 1:
The patent applies the dynamics principle by making the first chassis rotatable around a pivoting axis, allowing it to dynamically adjust from an extended initial position to a retracted position. This rotation enables the first traction means to contact bales at ground level and smoothly lift them, converting the static inclined plane into a dynamic system that adapts to the bale's position and reduces impact forces on the traction components.
Solution Approach 2:
The patent implements beforehand cushioning by introducing a damper assembly that absorbs impact energy before it can damage the traction tines and drag chains. The damper assembly compensates for the force of impact when the first chassis contacts bales, preventing the harmful rebound effect that would otherwise cause wear and breakage of the traction components.
2Productivity
If the dragging chains contact bales at high travel speed, then the picking up process is efficient, but the rebound effect causes loss of climbing effectiveness and material loss due to friction
Solution Approach 1:
The rotatable first chassis dynamically adapts to high-speed operation by rotating to the retracted position upon impact, allowing the first traction means to engage bales smoothly at ground level. This dynamic adjustment eliminates the harmful rebound effect that occurs with fixed inclined plane devices, maintaining climbing effectiveness and preventing material loss through friction even at high travel speeds.
Solution Approach 2:
The damper assembly provides beforehand cushioning by absorbing impact energy during high-speed operation. This cushioning effect prevents the rebound that would otherwise cause loss of climbing effectiveness and material loss, allowing the device to maintain high productivity without compromising on substance conservation.
3Speed
If the impact force with bales is increased to lift them quickly, then the pickup speed increases, but the frame structure weakens and ropes holding bales break
Solution Approach 1:
The rotatable first chassis provides a dynamic solution by rotating to the retracted position upon impact, allowing the bale lifting action to occur smoothly without transmitting excessive impact forces to the frame structure. This dynamic movement enables quick bale pickup while protecting the structural integrity of the frame and the ropes holding the bales.
Solution Approach 2:
The damper assembly implements beforehand cushioning by absorbing the impact force before it can damage the frame structure or break the ropes. This cushioning mechanism allows the device to lift bales quickly while maintaining the strength and integrity of the frame structure and rope components.
4Ease of operation
If the height of the inclined plane is reduced to minimize the step bales must climb, then the pickup process becomes smoother, but the traction means must work at lower elevation requiring closer ground contact
Solution Approach 1:
The rotatable first chassis provides a dynamic positioning mechanism that automatically adjusts the elevation of the first traction means. By rotating from the extended to the retracted position, the chassis brings the traction means closer to the ground contact point, creating a smoother pickup process without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The patent segments the lifting function into two distinct stages: the first traction means on the rotatable chassis handles ground-level engagement and initial lift, while the second traction means on the fixed chassis handles the inclined plane transport. This segmentation allows each component to be optimized for its specific function, achieving smooth operation without excessive overall complexity.
