Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching transponders to objects, such as beverage crates, are labor-intensive and inefficient, requiring mechanical contact and individual handling of each transponder.
Innovation Solution
A device and method utilizing a lance with a wing profile and air pressure to contactlessly attach transponders to objects, involving detection of unreadable transponders, cleaning, and vacuum-assisted transportation of transponders to the object, allowing for non-mechanical application and secure adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mechanical contact methods are used to attach transponders to objects, then secure attachment is achieved, but labor intensity and time consumption increase significantly
Solution Approach 1:
The patent replaces manual mechanical handling with an automated system that uses a lance equipped with a suction device and compressed air mechanism. The lance automatically positions, attaches, and secures transponders to objects without manual intervention, substituting human labor with an automated mechanical system that operates through coordinated suction and pressure cycles.
Solution Approach 2:
The patent employs pneumatic principles through the lance's suction device that creates negative pressure to hold the transponder, and subsequently applies positive pressure via compressed air to release and secure it. This pneumatic mechanism enables automated, contactless handling and attachment of transponders, dramatically reducing labor intensity while maintaining secure attachment.
2Manufacturing precision
If individual transponders are manually handled and attached, then precise placement is achieved, but production efficiency decreases
Solution Approach 1:
The lance system performs self-positioning and self-adjustment through its design features, including the wing profile that automatically orients the lance correctly and the suction mechanism that automatically grasps and positions the transponder. This self-service capability eliminates the need for manual positioning while maintaining precise placement accuracy.
Solution Approach 2:
The lance is pre-equipped with the suction device and compressed air mechanism before the attachment process begins. The wing profile is pre-configured to provide automatic orientation guidance. These preliminary preparations enable the system to execute precise, high-speed attachments without requiring manual intervention during the actual attachment process.
3Productivity
If compressed air is applied to the lance, then transponder release and secure attachment is achieved, but control precision challenges arise
Solution Approach 1:
The lance features a localized wing profile at its front end that creates a specific airflow pattern and pressure distribution zone. This localized structural feature ensures that compressed air is applied precisely where needed, maintaining control over the transponder release and attachment position even during high-speed operation.
Solution Approach 2:
The system dynamically transitions between suction mode (negative pressure) and release mode (positive pressure) through the lance's compressed air mechanism. This dynamic pressure control allows the system to adapt to different stages of the attachment process, maintaining precision while enabling high-speed operation.
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
Enables efficient, contactless, and secure attachment of transponders to objects, reducing labor and potential damage, while ensuring effective identification of crates through reliable transponder placement.
Implementation Method 1
A wing-like profile on the lance creates lift as the compressed air escapes. This results in a lower pressure between the lance and the transponder, allowing the wing profile to slide very close to the transponder
Implementation Method 2
the interior of this lance is pressurized with a vacuum to draw in and hold a transponder and insert it onto or into the object
Implementation Method 3
after reaching the object, the lance is pressurized so that the label is applied to the object without contact
