Solution Overview

Problem

Existing machine tools for machining flat workpieces face challenges in avoiding collisions between guides and equipment, leading to potential damage and limitations in flexibility and efficiency.

Innovation Solution

The machine tool design features adjustable beams with guides arranged below the upper surface, allowing carriages to move without contact, and includes multiple carriages with adjustable blocking members, such as suction cups, to securely hold workpieces while preventing collisions with the guides.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If guides are arranged on the upper surface of the beam for carriage movement, then carriages can be easily guided, but the guides are at risk of being hit by equipment and damaged

Engineering Contradiction:
Improvecarriage guidanceVSAvoidguide integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The guides are relocated from the upper surface of the beam to the lateral surfaces of the beam. This spatial relocation moves the guides to a different dimension (from top surface to side surfaces), allowing carriages to be guided while protecting the guides from being hit by equipment placed on the upper surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If equipment is mounted on the upper surface of the beam, then workpiece holding functionality is improved, but the risk of collision with guides increases

Engineering Contradiction:
Improveworkpiece holding capabilityVSAvoidcollision risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

By positioning guides on the lateral surfaces rather than the upper surface, the patent separates the guidance function from the equipment mounting area. This allows equipment to be freely mounted on the upper surface for various workpiece holding applications without creating collision risks with the guides, which are now located in a different spatial zone.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If guides are positioned at the upper surface level, then carriage engagement is simplified, but the guides are more exposed to potential damage

Engineering Contradiction:
Improvecarriage-guide engagementVSAvoidguide exposure to damage
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The guides are positioned on the lateral surfaces of the beam at a level that provides both easy engagement for carriages and protection from damage. This lateral positioning allows carriages to engage the guides from the side while the guides remain below the upper surface level, reducing their exposure to potential impacts from equipment.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
