Telescoping Bale Carrier Jaws Clear Strap Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 'C' clamp configured trucks and trailers face interference issues during bale loading and unloading due to overhead bale securing straps snagging against the uppermost bales, leading to inefficient and potentially damaging interactions.
Innovation Solution
The vehicle incorporates pivotable and telescoping bulkhead jaws with laterally and downwardly moving bale straps, utilizing hydraulic actuators to automatically adjust the straps' position, ensuring they clear the uppermost bales during loading and off-loading, and secure them effectively during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If overhead bale securing straps are used to secure uppermost bales, then bale securing is achieved, but the straps snag and interfere with loading and unloading operations
Solution Approach 1:
The patent makes the bale securing straps dynamically movable rather than fixed. The straps are attached to telescoping bulkhead jaws that can extend and retract, allowing the straps to move laterally and downwardly during loading and unloading operations to clear uppermost bales, then move into position to secure the bales during transport.
Solution Approach 2:
The patent introduces telescoping bulkhead jaws as intermediary mechanisms between the straps and the bales. These jaws extend upwardly to guide and position the straps, and can telescope downwardly to allow the straps to clear uppermost bales during loading and unloading operations.
2Device complexity
If fixed bale securing straps are used, then结构简单性 is maintained, but strap interference with uppermost bales occurs during loading and unloading
Solution Approach 1:
The patent transforms fixed straps into dynamic, movable straps by attaching them to telescoping bulkhead jaws. The jaws can extend and retract hydraulically, allowing the straps to automatically adjust their position - moving laterally and downwardly during loading/unloading to clear bales, then moving into securing position during transport.
Solution Approach 2:
The telescoping bulkhead jaws with integrated straps perform multiple functions automatically - they extend to guide and secure straps during transport, then retract to allow straps to clear uppermost bales during loading and unloading operations, eliminating the need for manual strap adjustment.
3Ease of operation
If telescoping bulkhead jaws with movable straps are implemented, then strap interference is eliminated, but device complexity increases
Solution Approach 1:
The telescoping bulkhead jaws serve multiple functions: they provide structural compression force against bales, guide and position the securing straps, and enable strap movement during loading/unloading operations. This multi-functionality consolidates several components into one integrated mechanism, managing the complexity.
Solution Approach 2:
The patent merges the bulkhead jaw structure with the strap attachment mechanism and the telescoping extension function into a single integrated assembly. The hydraulic actuation system for the telescoping jaws is combined with the strap positioning mechanism, reducing the number of separate components and control systems needed.
4Productivity
If movable bale straps are used to clear uppermost bales, then loading and unloading efficiency is improved, but energy consumption increases
Solution Approach 1:
The hydraulic actuators that drive the telescoping bulkhead jaws operate periodically rather than continuously - extending during transport to secure bales, then retracting during loading and unloading operations. This periodic operation minimizes energy consumption while maintaining the necessary functionality for both securing and clearing bales.
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
This configuration allows for seamless bale loading and unloading without strap interference, ensuring secure transport and reducing the risk of damage to the bales and equipment, while maintaining effective compression and securing mechanisms.
Implementation Method 1
powerful linear motion actuators which may forcibly slide the rear bulkhead jaw forwardly against loaded bales
Implementation Method 2
Each jaw among the 'C' clamp's front and rear bulkhead jaws preferably has a lower bulkhead segment, and has at least a first, and preferably first and second or left and right, pivotable upper bulkhead segments

AI summary
A bale carrier including a “C” clamp whose front and rear jaws have lower segments and upper segments, the “C” clamp having a load bed frame; first hydraulic cylinders connected to one of the jaws for extending and retracting the front and rear jaws, second hydraulic cylinders connected to the jaws' upper segments for extending and retracting the upper segments; bale straps extending between the jaws' upper segments, pivot joints interconnecting the jaws' lower and upper segments for pivoting the bale straps for bale securing and bale clearing; and a plurality of wheels fixedly attached to and extending downwardly from the load bed frame.
