Solution Overview

Problem

Large web processing equipment limits the versatility of web processing machines due to its inability to be easily moved from one station to another, restricting the production of various products.

Innovation Solution

A positioning apparatus with a linear axis and rotary axis, mounted to a web processing machine, allows for the movement of web processing equipment between stations by disengaging axis brakes, unlocking positioning pins, and implementing motion profiles to avoid interferences, enabling the equipment to be raised, moved, and lowered into operational positions across the machine face.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If large web processing equipment is mounted on a web processing machine, then the machine can process web material, but the equipment cannot be easily moved from one station to another, limiting versatility

Engineering Contradiction:
Improvemachine versatilityVSAvoidequipment mobility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by transforming the equipment mounting system from a static fixed position to a dynamic reconfigurable system. The positioning apparatus includes a linear axis with a carriage that can move along the linear axis, and a rotary axis that can rotate the mount and equipment. This dynamic positioning system allows the equipment to be moved between multiple web processing stations, enabling the web processing machine to handle different products and processes, thereby improving machine versatility while maintaining ease of operation through automated positioning control.

Inventive Principle:
Principle #15Dynamics

2Productivity

If web processing equipment is fixed at one station, then the equipment is stable and reliable, but the machine cannot quickly convert to produce different products

Engineering Contradiction:
Improveconversion speedVSAvoidequipment stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies the preliminary action principle by pre-positioning the equipment at multiple potential stations along the linear axis and preparing the positioning system in advance. The controller is pre-programmed with station positions and equipment parameters. When a product change is needed, the system quickly retrieves pre-stored positioning information and executes the movement to the appropriate station, enabling fast conversion between different products while maintaining equipment stability during operation at each station.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the equipment is made movable between stations, then versatility improves, but the positioning system becomes more complex

Engineering Contradiction:
Improveproduct varietyVSAvoidpositioning apparatus complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the universality principle by designing a multi-functional positioning apparatus that combines linear movement along the axis, rotary movement for angle adjustment, and automated control functions. The same positioning system serves multiple purposes: moving equipment between stations, orienting equipment at different angles, and accommodating various product types. This universal positioning platform reduces the need for separate specialized mechanisms for each function, thereby improving product variety capability while managing overall system complexity through integrated design.

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