Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual opening of sealed packages in warehouse facilities is time-consuming, inefficient, and poses an injury risk, as it requires each facility worker to carry a cutting tool.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual opening of packages is used, then workers can open packages with simple tools, but the process is time-consuming and inefficient
Solution Approach 1:
The patent replaces manual mechanical cutting with an automated laser cutting system that uses optical radiation to cut sealing elements. The laser system is controlled by a computing device that automatically detects package positions and controls cutting parameters, eliminating the need for workers to manually handle cutting tools and significantly increasing processing speed.
Solution Approach 2:
The system performs preliminary actions by pre-positioning packages on the conveyor system and pre-aligning them before cutting. The computing device pre-calculates cutting paths and parameters based on detected package characteristics, so that when a package reaches the cutting position, all parameters are already optimized for immediate cutting, reducing overall processing time.
2Ease of operation
If manual cutting tools are used by workers, then package opening can be performed, but injury risk increases
Solution Approach 1:
The patent replaces dangerous manual cutting operations with an automated laser cutting system. The laser is positioned and controlled remotely by a computing device, eliminating the need for workers to be in close proximity to cutting operations or to handle sharp cutting tools, thereby eliminating injury risk while maintaining ease of package opening.
Solution Approach 2:
The laser cutting system acts as an intermediary between the package and the worker. Instead of workers directly interacting with cutting tools, the automated system performs the cutting function remotely, mediating the dangerous interaction and protecting workers from harm while still achieving the desired package opening.
3Productivity
If high throughput cutting is implemented, then processing speed increases, but wear on cutting equipment increases
Solution Approach 1:
The patent uses a laser cutting system where cutting parameters (power, speed, focal position) can be dynamically adjusted by the computing device based on real-time detection of package characteristics. This allows optimal cutting parameters to be selected for each package, preventing excessive wear that would occur with fixed high-power settings, thereby maintaining high throughput while extending equipment life.
Solution Approach 2:
The laser cutting system is fully dynamic, with the computing device continuously adjusting cutting parameters based on detected package properties. The laser power, cutting speed, and focal position are dynamically modified for each package, allowing the system to operate at high throughput rates without applying excessive stress to the equipment, thus extending its operational duration.
4Productivity
If consistent package alignment is achieved, then cutting efficiency increases, but system complexity increases
Solution Approach 1:
The conveyor system is designed with multi-functional components that perform both transport and alignment functions. The same conveyor mechanism that moves packages through the system also automatically positions them for cutting, eliminating the need for separate alignment devices and reducing overall system complexity while maintaining high cutting efficiency.
Solution Approach 2:
The patent merges the alignment function with the conveyor system itself. Rather than adding separate alignment mechanisms, the conveyor is designed to inherently position packages correctly during transport, combining multiple functions into a single integrated system that achieves consistent alignment without proportionally increasing complexity.

Function Achieved in This Case
The system significantly increases throughput, reduces wear on equipment, and minimizes line stoppages by aligning packages for consistent cutting, allowing for efficient processing of up to 2000 packages per hour with reduced risk of injury.
Implementation Method 1
The optical radiation source applies the optical radiation to cut, damage, ablate, remove, pierce or burn the sealing element (e.g., tape) on the package
Data Source
AI summary
Systems and methods described herein are optimized for cutting sealing elements on packages using optical radiation. Packages can pass through a cutting device that applies the optical radiation to damage, vaporize, or cut the sealing element (e.g., tape) on the package. The systems and methods control several aspects of the cutting process to adjust throughput, improve efficiency, and reduce line stoppages. Systems can include an in-feed conveyor that orients packages and rejects packages that are out of specification, which can lead to issues such as jamming or damage to the equipment. Systems can include a variable-speed cut conveyor controlled by a computing system to dynamically adjust the speed of packages based upon historical cut quality, environmental measurement data, and height data related to a vertical dimension of the package.
