Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing systems for marking electrical conductors are limited to specific label applications and require manual mounting of printed labels, leading to increased material waste and inefficiency due to the need for separate units for printing and application.
Innovation Solution
A device with a mechanical interface for mounting to a printer, featuring a pivotable eccentric mechanism that moves the print head and print medium between printing and open positions, allowing for efficient printing and application of markings around conductors without additional material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the functionality required for the application is shifted to a unit that can be separated from the printer, then the adaptability of the printing system is improved, but the printing material is wasted due to the additional feed path without printing
Solution Approach 1:
The print head is made dynamically movable between a printing position (where it contacts the print medium) and an open position (where it is separated from the print medium). This dynamic positioning allows the system to adapt between different operational modes: when the applicator is attached, the print head moves to the open position during non-printing feed to prevent material waste; when the applicator is removed, the print head returns to the printing position for standard printing operations.
Solution Approach 2:
The printing system is designed with universal functionality to operate in multiple modes: it can function as a standalone printer or integrate with an applicator device for automated label application. The mechanical interface and movable print head enable the same printer to serve both purposes, providing versatility while preventing material waste through intelligent positioning based on the attached configuration.
2Adaptability or versatility
If a separable applicator unit is used to extend functionality, then the versatility of the system is improved, but the device complexity increases due to the additional mechanical interface and motion control
Solution Approach 1:
The mechanical interface is designed with universal compatibility, using standard components such as a centering pin and lever mechanism that can accommodate different applicator configurations. This universal design approach enables the printer to work with various separable units while maintaining a relatively simple and standardized interface structure, thereby improving versatility without proportionally increasing complexity.
3Device complexity
If the print head remains in contact with the print medium during non-printing feed, then the system simplicity is maintained, but the printing material is wasted
Solution Approach 1:
The print head is equipped with a movable mechanism that dynamically adjusts its position based on operational requirements. During non-printing feed operations when an applicator is attached, the print head automatically moves to the open position, separating from the print medium to prevent unnecessary material consumption. This dynamic behavior resolves the contradiction by introducing minimal complexity that yields significant material savings.
Solution Approach 2:
The system incorporates self-regulating behavior where the presence or absence of the applicator automatically triggers the appropriate print head positioning through mechanical linkage. The lever mechanism and eccentric component create self-actuating motion that requires minimal external control, allowing the system to automatically prevent material waste without complex control systems.

Enables flexible and efficient marking of conductors by allowing the same printer to be converted for different applications without increasing material consumption, reducing manual effort and waste, and enabling automatic motion of the print head for saving printing material.
Implementation Method 1
at least one eccentric supported at the material interface to be pivotable about a pivot axis; and at least one print head actuator configured to move the at least one eccentric into a first pivot position and into a second pivot position different from the first pivot position

AI summary
A device for providing a marking arranged or arrangeable around an object includes: a mechanical interface for releasably or irreversibly mounting the device to a printer; a material interface for receiving a print medium, which is printed by the printer using a print head, as a printed product in a longitudinal direction; at least one eccentric supported at the material interface to be pivotable about a pivot axis; and at least one print head actuator for moving the at least one eccentric to a first pivot position and to a second pivot position different from the first pivot position to provide the marking originating from the printed product. The eccentric, in a state of the device mounted to the printer using the mechanical interface, moves the print head and the print medium towards each other into a printing position for printing the print medium when the eccentric moves.
