Solution Overview

Problem

The existing wire electrical discharge machine requires a lengthy clamping process for transportation due to individual clamping of multiple components, making preparation troublesome.

Innovation Solution

A machine tool configuration that includes a first clamp member to fix the relative position between the bed and the table, reducing the number of clamp members and shortening the clamping time, with additional clamp members fixing the positions of the column and quill to suppress movement without individual clamping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multiple components (saddle, table, UV-axis saddle, UV-axis table, quill) are individually clamped to prevent movement during transportation, then the stability and position fixation is improved, but the number of clamp members increases and the clamping time becomes long

Engineering Contradiction:
Improveposition fixationVSAvoidclamping time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent combines multiple clamping functions into a single integrated clamp member structure. The clamp member includes a clamp body with multiple clamping portions that can simultaneously clamp the saddle, table, and UV-axis components, reducing the total number of clamp members needed while maintaining position fixation stability during transportation

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If multiple components are individually clamped with separate clamp members, then each component's position is securely fixed, but the device complexity and number of clamp members increase

Engineering Contradiction:
Improvecomponent position fixationVSAvoidnumber of clamp members
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent integrates multiple clamping functions into a single clamp member structure with multiple clamping portions. This unified structure can simultaneously secure the saddle, table, and UV-axis components, reducing the total number of separate clamp members while maintaining secure position fixation for all components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The clamp member is designed as a multi-functional device where a single clamp body can perform multiple clamping operations on different components (saddle, table, UV-axis saddle, UV-axis table, quill). This universal design reduces the number of specialized clamp members needed while ensuring stable position fixation for all components

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

AI summary

This machine tool comprises: a saddle which moves relative to a bed in a first direction; a table which moves relative to the saddle in a second direction perpendicular to the first direction; and a first clamp member which is fixed to the bed and the table and fixes the relative position of the bed and the table.
