Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing processing apparatuses, such as laser and dicing machines, require operators to repeatedly confirm and operate multiple buttons to adjust the display of a workpiece, making the process tedious and time-consuming, especially for fine adjustments.

Innovation Solution

A processing apparatus with a touch-sensitive display that allows operators to move and rotate images of a workpiece by touching the screen, with the system automatically controlling the movement mechanisms based on the touch coordinates, eliminating the need to manually operate individual buttons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operator uses traditional button controls to adjust the display area, then the display can be adjusted, but the operation becomes tedious and time-consuming

Engineering Contradiction:

Improveease of display adjustmentVSAvoidtime for fine adjustments

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical button-pressing system with a touch-screen interface that responds to finger movements. The touch-screen display detects the position and movement of the operator's finger, translating these movements into corresponding adjustments of the displayed image area, thereby eliminating the need for repeated button operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The touch-screen display acts as an intermediary between the operator and the image capturing unit. Instead of directly controlling movement mechanisms through buttons, the operator interacts with the visual display itself, which then communicates the desired adjustments back to the system, streamlining the control process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If the operator needs to make fine adjustments to the display area, then precision can be achieved, but multiple button presses are required which is tedious

Engineering Contradiction:

Improveprecision of display positioningVSAvoidoperational simplicity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The touch-screen interface replaces the discrete mechanical button system with a continuous digital interface. By detecting the position and movement of the finger on the screen, the system enables precise control of the displayed image area through smooth, continuous adjustments rather than discrete button presses, achieving both precision and operational simplicity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

In a method of controlling a processing apparatus having a touch-panel display: when an operator touches the display with a finger and moves the finger in an X-axis direction, a chuck table or a processing unit is moved in the X-axis direction for a distance depending on the distance that the finger is moved, and an image of a portion of a workpiece is moved in the X-axis direction on the display; and when the operator touches the display with a finger and moves the finger in a Y-axis direction, the chuck table or the processing unit is moved in the Y-axis direction for a distance depending on the distance that the finger is moved, and the image of the portion of the workpiece is moved in the Y-axis direction on the display.
