Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a traditional integrated bridge design is used, then structural strength is maintained, but manufacturing complexity and alignment precision are worsened

Engineering Contradiction:
Improvealignment precisionVSAvoidmanufacturing complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bridge is divided into multiple modular components including a carrier component, support components, and guide means that can be manufactured separately and assembled together. This segmentation enables each component to be precision-manufactured independently using standard machining processes, improving overall alignment precision while reducing manufacturing complexity through modular assembly

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support surface is designed with an inclined orientation at a specific angle relative to the second axis, creating a three-dimensional geometric relationship that naturally aligns the carrier with the guide means. This angular dimension provides self-aligning features that simplify assembly and improve precision without requiring complex adjustment mechanisms

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

2Ease of operation

If the laser processing unit is positioned far from the bridge, then accessibility is improved, but weight distribution and compactness are worsened

Engineering Contradiction:
ImproveaccessibilityVSAvoidcompactness
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The bridge and carrier are designed with asymmetric geometric features including inclined surfaces and offset mounting positions that create an optimized weight distribution. The carrier is positioned at an angle and distance that balances accessibility requirements with compact overall dimensions, preventing excessive overhang while maintaining operational access

Inventive Principle:
Principle #4Asymmetry

3Reliability

If multiple guide means are provided on the bridge, then guidance reliability is improved, but device complexity is worsened

Engineering Contradiction:
Improveguidance reliabilityVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple guide means are implemented as separate, standardized modular components rather than integrated features. Each guide means can be independently manufactured, installed, and maintained, improving guidance reliability through redundancy while managing complexity through standardization and modularity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide means are designed with universal mounting interfaces and standardized geometries that allow the same component design to be replicated at multiple locations. This universality enables reliable multi-point guidance while reducing overall system complexity through component standardization

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

AI summary

The invention relates to a bridge for a laser processing machine (1), in particular a laser cutting machine, wherein the bridge (5) comprises a support (6) which extends along a first axis (y) and has a receiving side (7) for movably guiding a laser processing unit (9) along the first axis (y), and wherein one or more guide means (17) are provided on the bridge (5) for movably guiding the bridge (5) along a second axis (x), which runs essentially perpendicular to the first axis (y). In the bridge according to the invention, each guide means (17) is provided in a separate support component (13), which is detachably connected to the carrier (6) and has a support surface (22), on which the carrier (6) rests with a contact surface (29), wherein the support surface (22) runs perpendicular to the receiving side (7) and is inclined at an angle of inclination (α) relative to the second axis (x), so that the support surface (22), with increasing distance from the receiving side (7) of the bridge (5), approaches a base (19) of the support component (13), which faces away from the support surface (22).
