Solution Overview

Problem

The existing band take-up devices require manual and time-consuming fixation of the tape end after cutting, which is tedious and inefficient in industrial production settings, especially when handling and transporting full coils.

Innovation Solution

A tape take-up device with a thermal energy introduction system, using either a heating element or electrodes to melt and weld the tape end to the already wound tape on the coil, eliminating the need for manual adhesive fixation and allowing for adjustable and precise connection strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual fixation of the tape end is used, then the tape can be secured to the full reel, but the process is time-consuming and tedious

Engineering Contradiction:
Improvetape fixation reliabilityVSAvoidproduction efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical fixation process with an automated thermal welding system. The welding device applies heat to melt the tape end and bond it to the full reel, eliminating the need for manual adhesive application and securing operations. This substitution of mechanical/manual processes with thermal/automated processes directly resolves the contradiction by maintaining reliable fixation while dramatically improving production efficiency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The thermal welding system enables the tape to secure itself to the reel through automated heating and melting. The tape end is automatically positioned, heated, and bonded without requiring manual intervention for adhesive application or securing. This self-service automation maintains fixation reliability while eliminating the time-consuming manual operations that reduced productivity.

Inventive Principle:
Principle #25Self-service

2Extent of automation

If thermal energy is introduced into the tape, then the tape melts and adheres to the wound tape automatically, but additional equipment is required

Engineering Contradiction:
Improvefixation process automationVSAvoidwinding device complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent integrates the thermal welding device directly into the existing tape winding system. The welding device is combined with the winding mechanism so that the tape can be continuously wound and automatically welded at the appropriate moment without requiring separate standalone equipment. This merging of functions achieves high automation while minimizing the increase in overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The winding device is designed to perform multiple functions: winding the tape onto the reel and automatically welding the tape end to the full reel. By making the device universal and multi-functional, the patent achieves automated fixation without proportionally increasing device complexity, as the same system handles both winding and welding operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the tape is melted superficially, then the tape can be easily detached if necessary, but the bonding strength may be reduced

Engineering Contradiction:
Improvetape detachment easeVSAvoidbonding strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent controls the thermal welding parameters (temperature, duration, pressure) to achieve superficial melting of the tape. By precisely adjusting these parameters, the system creates a bond that is sufficiently strong for handling and transport while remaining detachable if needed. This parameter control allows optimization of both bonding strength and ease of detachment, resolving the contradiction between these opposing requirements.

Principle #35Parameter changes
