Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate cutting tools are used to sever binding elements, then the binding machine can perform cutting function, but the device complexity increases
Solution Approach 1:
The patent combines the cutting function and welding function into a single laser device. The laser welding device emits a laser beam that can both weld overlapping sections of the binding element together and cut through the binding element to sever it, eliminating the need for separate cutting tools and reducing machine complexity.
Solution Approach 2:
The laser welding device is designed to perform multiple functions: it can weld binding element sections together to secure the loop around objects, cut through the binding element to release it, and potentially perform other operations. This multi-functionality reduces the number of separate components needed in the machine.
2Adaptability or versatility
If separate cutting tools are used, then cutting can be performed, but the quantity of components increases
Solution Approach 1:
The patent merges the cutting tool and welding device into a single laser welding device. The laser beam serves dual purposes: welding overlapping binding element sections together and cutting through the binding element to sever it, thereby reducing the total number of components in the system.
3Ease of manufacture
If binding element coils are not fully utilized, then splicing is not required, but waste of binding element increases
Solution Approach 1:
The laser welding device performs preliminary welding to join the end of one binding element coil to the beginning of the next coil before the binding process is complete. This allows continuous operation without interruption and ensures full utilization of each binding element coil, minimizing waste.
Solution Approach 2:
The splicing capability enabled by the laser welding device allows binding element coils to be joined seamlessly, maintaining continuous operation of the binding machine. This continuity ensures that each coil is fully utilized before splicing to the next coil, preventing waste of partially used binding elements.

AI summary
A binding machine comprising: —a feeding device for feeding a binding element (3) in the form of a wire or strap in a loop around one or more objects to be bound and subsequently retracting the binding element to draw it tightly around said objects; and—a laser welding device for forming a welded joint between a section at the leading end of the binding element and an adjoining section at the trailing end of the part (3a) of the binding element fed in a loop around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device is configured to cut off the binding element at said trailing end to thereby release said part (3a) of the binding element from the remaining part (3b) of the binding element.
