Solution Overview

Problem

Current panel processing systems are not operated efficiently and safely, as they rely on pre-programmed sequences that do not adapt to the actual status of the workpiece or operator, requiring significant cognitive effort and lacking intuitive feedback.

Innovation Solution

A panel processing system that incorporates a light signal device capable of emitting optical signals based on the actual status of the workpiece and operator, using lighting modes such as color, duration, rhythm, and location to provide intuitive and adaptive feedback, enhancing operator interaction and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If pre-programmed sequences are used to control panel processing systems, then the system can operate automatically, but the operator requires significant cognitive effort and the system lacks adaptability to actual status

Engineering Contradiction:
Improveautomatic operationVSAvoidcognitive effort
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The patent implements feedback by using detection devices to monitor the actual status of workpieces and operators, then using light signaling devices to provide real-time visual feedback. This allows the automated system to adapt to actual conditions without requiring the operator to constantly monitor and interpret complex programmed sequences, thereby reducing cognitive effort while maintaining automation.

Inventive Principle:
Principle #23Feedback

2Extent of automation

If pre-programmed sequences are used to control panel processing systems, then the system can operate automatically, but the system cannot adapt to the actual status of workpiece or operator

Engineering Contradiction:
Improveautomatic operationVSAvoidadaptability to actual status
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The system uses detection devices to continuously monitor actual workpiece status and operator actions, feeding this information back to the control unit which then adjusts light signaling accordingly. This enables the automated system to adapt to real-time conditions without losing automation benefits.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent makes the system dynamic by transitioning from static pre-programmed sequences to dynamic light signaling that changes in real-time based on detected status. The light signals adapt their color, position, and pattern dynamically according to actual workpiece position and operator actions, enabling adaptability while maintaining automatic operation.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If conventional screens or projectors are used to display information, then detailed information can be provided, but the operator requires relevant cognitive abilities and the interface becomes complex

Engineering Contradiction:
Improveinformation transmissionVSAvoidcognitive ability requirement
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent uses color changes in light signals to convey different types of information and status. Different colors represent different meanings (e.g., green for ready, red for stop), allowing detailed information transmission through intuitive color coding that requires minimal cognitive processing compared to text-based displays.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent replaces complex mechanical/electronic display systems (screens and projectors) with a simplified light signaling system. This substitution maintains information transmission capability while dramatically reducing the cognitive abilities required, as light signals are intuitively understood without requiring literacy or interpretation skills.

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

4Reliability

If the light signal device provides comprehensive real-time feedback, then operator safety and efficiency improve, but the device complexity increases

Engineering Contradiction:
Improveoperator safetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the information feedback system into simple, discrete light signals rather than one complex display system. Multiple simple light sources are distributed at relevant locations, each providing specific feedback. This segmentation improves safety through comprehensive coverage while keeping individual components simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light signaling devices act as intermediaries between the complex automated system and the operator. They translate complex system status into simple, intuitive visual signals that the operator can easily understand and respond to, thereby improving safety without requiring the operator to directly interact with or understand the complex underlying system.

Inventive Principle:
Principle #24Intermediary (Mediator)
