Solution Overview

Problem

Existing packaging strap cutting methods are time-consuming and prone to inconsistent lengths, leading to user fatigue and reduced efficiency, as they require manual calculation and cutting of strap lengths.

Innovation Solution

A packing strap length cutting apparatus featuring a motor-driven strap pulling unit and a cutting unit with a positioning plate and blades, allowing for automatic cutting of a predetermined strap length, facilitated by a control device and sensing units to ensure precise and efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual pulling and cutting of packing strap is used, then device complexity is reduced, but productivity decreases and measurement precision is poor

Engineering Contradiction:
Improvecutting operation efficiencyVSAvoidapparatus structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The apparatus is divided into distinct functional modules: a strap pulling unit with motor and roller, a cutting unit with upper and lower blades, and a control unit. Each module performs a specific function (pulling, cutting, controlling), allowing the system to achieve automated precision cutting while maintaining reasonable structural complexity through functional segmentation.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If manual calculation and cutting of strap length is performed, then device complexity remains low, but measurement precision and consistency deteriorate

Engineering Contradiction:
Improvestrap length accuracyVSAvoidcutting apparatus
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The control unit receives input regarding the required strap length and coordinates the motor-driven pulling unit to dispense the exact predetermined length before activating the cutting unit. This feedback-controlled process ensures precise and consistent strap length measurement and cutting, eliminating manual measurement errors.

Inventive Principle:
Principle #23Feedback

3Productivity

If automated strap pulling and cutting is implemented, then productivity increases, but device complexity and initial time investment increase

Engineering Contradiction:
Improvecutting operation speedVSAvoidsetup and initialization time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The apparatus is pre-configured with the control unit programmed with the required strap length parameters. Before operation, the system is prepared with the cutting position and pulling distance predetermined, allowing the motor to automatically pull and cut the strap without manual intervention during actual use, thus reducing per-operation time after initial setup.

Inventive Principle:
Principle #10Preliminary action

AI summary

A packing strap length cutting device includes a main body and a control device. The main body has a first frame and a second frame. A strap pulling unit, a calculation unit and a sensing unit are electrically connected to the control device. The strap pulling unit is connected to a strap connecting unit. Thereby, a packing strap can be automatically pulled out a predetermined length through the strap pulling unit, and then the strap cutting unit is driven by a driving member of the strap pulling unit to cut the packing strap in the predetermined length, assisting a user in completing the cutting operation quickly.
