Solution Overview

Problem

Conventional conical crimping and sealing machines have low production capacities, suffer from product tearing and misalignment issues, especially at high speeds, and face challenges with thin or slippery materials, leading to decreased packaging quality and safety concerns due to hot glue contamination.

Innovation Solution

A high-capacity conical crimping and sealing machine with advanced features such as a product loading edge alignment system, a circular product loading drum with high-friction coating, and a servo-controlled feeding system that ensures continuous and synchronized feeding, gluing, and crimping, preventing angular rotation and double feeding, while maintaining precise alignment and pressure to handle various product sizes efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional machines use claws to hold products at an angle during feeding, then products can be kept stable, but products separate from the chamber and tear when accelerating to high speeds

Engineering Contradiction:
Improveproduct stabilityVSAvoidfeeding speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The feeding system is divided into multiple zones: a loading chamber for stable product placement, a transition zone with gradually reducing claws, and a feeding zone for high-speed operation. This segmentation allows products to be held stably during loading while enabling smooth acceleration without tearing during feeding.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The claw length and angle are made dynamically adjustable during the feeding process. The claws start at a longer length and steeper angle for stable product holding, then gradually reduce in length and angle as products are fed, allowing smooth acceleration to high speeds without product damage.

Inventive Principle:
Principle #15Dynamics

2Reliability

If claws are made long to keep products stable, then products can be held at angle, but products separate from chamber and tear during acceleration

Engineering Contradiction:
Improveproduct holding stabilityVSAvoidproduct tearing
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The claw dimensions and positioning are dynamically adjusted during the feeding cycle. Initially, longer claws at steeper angles provide stable product holding. As feeding progresses, claws gradually retract and reduce in length, maintaining product stability while enabling smooth acceleration without causing product separation or tearing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Products are pre-positioned and stabilized in the loading chamber using the full-length claws before feeding begins. This preliminary stable positioning ensures products are properly oriented and secured before the feeding system accelerates, preventing tearing during the transition to high-speed operation.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If machine speed is increased to improve production capacity, then productivity increases, but product tearing and misalignment occur

Engineering Contradiction:
Improveproduction capacityVSAvoidproduct alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The machine employs dynamic speed control where the feeding system accelerates gradually rather than operating at constant high speed. The claw angle and position are simultaneously adjusted during acceleration, maintaining product alignment precision even as production capacity increases through higher operating speeds.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Sensors monitor product position and alignment in real-time during high-speed feeding. The control system uses this feedback to dynamically adjust claw positioning and feeding speed, ensuring products remain properly aligned even at increased production capacities.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If conventional machines use horizontal stacking at 70 degrees, then loading is simplified, but chamber changes are needed for different product sizes causing long changeover times

Engineering Contradiction:
Improveloading simplicityVSAvoidproduct size adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The loading chamber is designed with universal, adjustable components including variable-angle support bars and reconfigurable claw mechanisms. These multi-functional elements can accommodate different product sizes and shapes without requiring chamber changes, maintaining simple loading operations while providing versatility for various product specifications.

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

Solution Approach 2:

The chamber geometry and support structures are made dynamically adjustable rather than fixed. Support bar angles and claw positions can be modified during operation to suit different product sizes, eliminating the need for physical chamber changes and reducing changeover times while maintaining ease of loading.

Inventive Principle:
Principle #15Dynamics
