Solution Overview

Problem

Conventional lamination shaping apparatuses face challenges in reducing machining errors during subsequent cutting while avoiding upsizing and cost increases, and they struggle with simultaneous laser machining and cutting, leading to increased time and dimension errors in secondary machining.

Innovation Solution

A lamination shaping apparatus with a machining head that includes a tool bit capable of shaping reference surfaces perpendicular and parallel to the shaping table, allowing for precise positioning and reducing the need for large drivers, enabling downsizing and minimizing cutting allowances.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a combined machine includes a driver for operating a cutting tool, then cutting capability is improved, but the entire machine or chamber tends to be upsized

Engineering Contradiction:
Improvecutting capabilityVSAvoidmachine size
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent extracts the cutting function from a separate dedicated machine and integrates only the essential cutting capability into the lamination shaping apparatus. By removing unnecessary components and keeping only the critical cutting elements, the apparatus achieves cutting capability without requiring the full size of a conventional combined machine.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The machining head is designed to perform multiple functions - both lamination shaping and cutting operations. This multi-functionality allows the apparatus to handle both forming and finishing operations without requiring separate dedicated machines, thereby avoiding the size increase associated with full combined machines while maintaining versatility.

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

2Ease of manufacture

If a combined machine performs dry cutting without cutting oil, then lubrication effects are lost, but high runout accuracy must be maintained to suppress tool runout

Engineering Contradiction:
Improvedry cutting capabilityVSAvoidrunout accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the conventional mechanical cutting system with high runout requirements with a cutting tool that operates with minimal runout through alternative mechanical design. The cutting tool is designed to accommodate dry cutting conditions while maintaining sufficient precision through modified mechanical characteristics rather than relying on high runout accuracy.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Volume of stationary object

If a lamination shaping apparatus does not have a cutting mechanism, then the apparatus remains small, but the shaped product must be fed to another machine for secondary machining

Engineering Contradiction:
Improveapparatus sizeVSAvoiddimensional accuracy in secondary machining
Core Design Contradiction:
Volume of stationary objectVSManufacturing precision

Solution Approach 1:

The patent merges the lamination shaping function with a simplified cutting mechanism in a single integrated apparatus. This combination allows the shaped product to undergo both forming and finishing operations in one machine, eliminating the need for secondary machining on separate equipment and the associated dimensional accuracy problems.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If a combined machine performs laser machining and cutting simultaneously, then production line efficiency is improved, but the machine complexity increases

Engineering Contradiction:
Improvesimultaneous operation capabilityVSAvoidmachine complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the simultaneous operations into sequential or semi-independent functions. The lamination shaping and cutting operations are designed to be performed in a coordinated manner rather than fully simultaneous, reducing the complexity of coordinating multiple high-speed operations while still improving overall productivity compared to completely separate processes.

Inventive Principle:
Principle #1Segmentation
