Solution Overview

Problem

Conventional multi-tool gantry machining centers face a trade-off between the number of tools and processing efficiency due to the inverse proportionality between the travel length of movable seats and the number of seats, leading to increased base construction costs and space inefficiency.

Innovation Solution

An extendable gantry with a transverse bridge that has an axial length greater than its width, allowing multiple movable seats with constant travel length without requiring additional base length, featuring a working area for active seats and a waiting area for idle seats, enabling efficient tool processing and compact design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of movable seats is increased to provide diversity of tools, then the tool diversity is improved, but the travel length of each movable seat decreases

Engineering Contradiction:
Improvetool diversityVSAvoidtravel length of movable seat
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The transverse bridge extends in the X-axis direction beyond the base width, creating an extended dimension for the movable seats to travel. This allows multiple movable seats to be accommodated while maintaining sufficient travel length in the Y-axis direction, effectively adding spatial dimension to resolve the contradiction between tool diversity and travel length.

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

2Adaptability or versatility

If the number of movable seats is increased to provide diversity of tools, then the tool diversity is improved, but the processing efficiency decreases

Engineering Contradiction:
Improvetool diversityVSAvoidprocessing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By extending the transverse bridge in the X-axis direction beyond the base width, the invention creates additional spatial room that allows multiple movable seats to operate with adequate travel length in the Y-axis direction. This dimensional extension enables both high tool diversity and maintained processing efficiency simultaneously.

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

3Length of moving object

If the base width is increased to accommodate more movable seats with sufficient travel length, then the travel length is maintained, but the construction cost increases

Engineering Contradiction:
Improvetravel length of movable seatVSAvoidconstruction cost
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

Instead of increasing the base width in the X-axis direction to accommodate more movable seats, the invention extends the transverse bridge beyond the base width in the X-axis direction. This allows the base to remain compact and cost-effective while the transverse bridge provides the necessary extended space for multiple movable seats to travel with sufficient length.

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

4Length of moving object

If the base width is increased to accommodate more movable seats with sufficient travel length, then the travel length is maintained, but the space usage becomes inefficient

Engineering Contradiction:
Improvetravel length of movable seatVSAvoidbase area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The invention extends the transverse bridge in the X-axis direction beyond the base width, effectively utilizing the extended dimension rather than expanding the base area. This allows multiple movable seats to have sufficient travel length while the base maintains a compact footprint, optimizing space usage efficiency.

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