Solution Overview
Problem
Existing label producing apparatuses require multiple motors for cutting and discharging mechanisms, leading to increased size, weight, and cost due to the complexity of separate motor systems.
Innovation Solution
A label producing apparatus utilizing a single motor to drive both the cutting and discharging mechanisms through a gear mechanism and coordinated movement of a movable blade and driven roller, reducing the number of motors needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate motors are provided for the cutting mechanism and tape discharging mechanism, then the reliability of each function is improved, but the device size and weight increase
Solution Approach 1:
The patent combines the cutting mechanism and tape discharging mechanism into a single integrated unit sharing one motor. The motor drives both the movable blade for cutting and the driving roller for tape discharge through a unified mechanical structure, eliminating the need for separate motors and reducing overall apparatus weight while maintaining functional reliability through coordinated operation.
Solution Approach 2:
The single motor in the integrated mechanism serves multiple functions: it drives the movable blade for cutting the label tape and simultaneously drives the driving roller for discharging the cut label. This multi-functional design reduces the number of components and apparatus weight while ensuring both cutting and discharging functions operate reliably under unified control.
2Ease of operation
If separate motors are provided for the cutting mechanism and tape discharging mechanism, then each function can be controlled independently, but the device complexity increases
Solution Approach 1:
The patent merges the cutting mechanism and tape discharging mechanism into a single integrated unit with one motor, reducing motor system complexity from two separate systems to one unified system. The integrated design simplifies the overall structure while maintaining operational effectiveness through coordinated mechanical linkages.
Solution Approach 2:
The integrated mechanism employs dynamic coordination where the movable blade and driven roller advance and retreat in a coordinated sequence driven by the single motor. This dynamic coordination allows the system to perform cutting and discharging functions sequentially with appropriate timing, maintaining ease of operation without requiring independent motor control.
3Weight of stationary object
If a single motor drives both cutting and discharging mechanisms, then the apparatus size is reduced, but the coordination between mechanisms becomes more difficult
Solution Approach 1:
The patent combines cutting and discharging mechanisms into one integrated unit sharing a common motor and mechanical linkages. This integration reduces apparatus weight and simplifies the overall structure while the internal mechanical design ensures proper coordination between the movable blade and driven roller through shared structural elements.
Solution Approach 2:
The integrated mechanism uses dynamic coordination where the movable blade and driven roller advance and retreat in a coordinated sequence. The single motor drives both components through mechanical linkages that ensure proper timing and sequencing, allowing the system to perform cutting followed by discharge operations smoothly without requiring complex independent control systems.
