Solution Overview

Problem

Existing methods for transmitting instructions to operators on process units, such as those used in woodworking or plastic processing, are prone to errors and time-consuming, especially when actions need to be performed at locations distant from the control panel, leading to increased risk of incorrect machine adjustments and operator safety hazards.

Innovation Solution

A method utilizing a contactless interface to transmit process data from a process unit to a portable conversion device, such as a smartphone, via optical or wireless means, allowing operators to access instructions as coded symbols like QR codes, enabling error-free and timely access to handling instructions without mechanical connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If instructions are displayed on the control panel, then the operator can access handling instructions, but the operator must walk back and forth between the control panel and the machine location, increasing time consumption and error risk

Engineering Contradiction:
Improveinstruction transmission accuracyVSAvoidoperator travel time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

A portable conversion device (smartphone, tablet, or portable display) serves as an intermediary between the control panel and the operator. The device receives process data via wireless transmission (Bluetooth, Wi-Fi, or other wireless protocols) from the control panel and displays the converted instructions locally at the machine location, eliminating the need for the operator to return to the control panel repeatedly.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical system of physical paper printing with an electronic wireless transmission system. Instead of printing instructions on paper (mechanical process), the system uses wireless data transmission and electronic display to deliver instructions instantly to the portable device, reducing both time and material consumption.

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

2Ease of operation

If a printer is provided on the control panel to print action information, then the operator has instructions at the location, but providing a printer on each machine is expensive and printing is time-consuming and error-prone

Engineering Contradiction:
Improveinstruction accessibilityVSAvoidhardware cost
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The portable conversion device serves multiple functions: it acts as a display instrument, a wireless receiver, and an instruction converter. Instead of requiring separate printers at each machine location, a single portable device can serve multiple machines by moving between locations, reducing overall hardware requirements and costs.

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

Solution Approach 2:

The system creates digital copies of the control panel's process data and transmits them wirelessly to the portable device. This eliminates the need for physical printing while providing the operator with accessible instructions at the machine location, reducing both hardware costs and time consumption.

Inventive Principle:
Principle #26Copying

3Loss of time

If additional display instruments are provided on the machine, then the operator travels less distance, but the purchase of additional display instruments is expensive

Engineering Contradiction:
Improveoperator travel timeVSAvoidhardware cost
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The display location is made dynamic rather than static. Instead of installing fixed display instruments at multiple predetermined locations, the portable conversion device can be dynamically positioned wherever the operator needs instructions, providing flexibility and eliminating the need for expensive fixed installations at every possible location.

Inventive Principle:
Principle #15Dynamics
