Solution Overview

Problem

Gantry machine tools pose safety risks due to elevated support structures that require protective barriers and complex guide systems, complicating accessibility and increasing installation and maintenance costs.

Innovation Solution

The gantry machine tool features support structures that are coplanar with the worktable, incorporating guides on lateral surfaces for carriage movement, eliminating height differences and allowing a walkable surface, reducing the need for protective barriers and simplifying access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If support structures are raised or embedded in the floor to support carriages, then structural stability is improved, but operator safety deteriorates due to increased risk of falling and injury

Engineering Contradiction:
Improvestructural stabilityVSAvoidoperator safety
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent relocates the guide means from the upper surface of the support structure to its lateral surface. This dimensional shift allows the horizontal top surface to remain flat and walkable while the guides are positioned on the vertical side, eliminating the need for protective barriers and improving operator safety without compromising structural stability

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

2Manufacturing precision

If guide means are positioned on the upper surface of support structures, then carriage guidance is improved, but accessibility deteriorates due to need for protective covers and roller shutters

Engineering Contradiction:
Improvecarriage guidanceVSAvoidaccessibility
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The guide means are positioned on the lateral surface of the support structure rather than the upper surface. This allows the horizontal top surface to remain completely walkable and accessible, while the guides function effectively on the vertical side surface, eliminating the need for telescopic covers or roller shutters

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

3Object-affected harmful factors

If protective barriers are installed around support structures, then operator safety is improved by preventing accidental contact, but device complexity increases due to additional components

Engineering Contradiction:
Improveoperator safetyVSAvoidprotective barrier system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent extracts the guide means from the upper surface location and relocates them to the lateral surface of the support structure. This removal of guides from the walkable surface eliminates the need for protective barriers entirely, as operators can safely walk over the entire top surface without risk of contacting moving guide components

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lateral surface guides inherently provide safety by being positioned on the vertical side rather than the horizontal top. The structure itself serves the dual function of supporting carriages and eliminating safety hazards, without requiring additional protective barrier systems

Inventive Principle:
Principle #25Self-service

4Reliability

If telescopic covers or roller shutters are used to protect guide means, then structural protection is improved, but ease of operation deteriorates due to slippery surfaces and need to skirt around

Engineering Contradiction:
Improvestructural protectionVSAvoidwalkability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By positioning guide means on the lateral surface rather than upper surface, the entire horizontal top surface remains as a continuous walkable area. Operators can walk directly over the support structures without encountering slippery covers or needing to navigate around obstacles

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