Solution Overview

Problem

Existing laser machines face challenges in safe and easy handling of tool holders during assembly and disassembly, often resulting in complicated and potentially hazardous processes.

Innovation Solution

A laser machine with a guiding system that allows sideways movement of the tool holder into or out of a tool bay, combined with a locking system using operable locking magnets and an adjustment system with screw elements and contact elements for precise alignment, ensuring safe and easy handling and alignment of the tool holder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the tool holder is removed from the laser machine using conventional methods, then the tool holder can be detached, but the process becomes complicated and time-consuming

Engineering Contradiction:
Improveease of disassemblyVSAvoidtime for disassembly
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The locking system is segmented into multiple independent locking elements (first locking element, second locking element) that can be individually actuated. This allows the tool holder to be released in a controlled sequence, simplifying the disassembly process while maintaining security during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking elements are designed to be dynamically controllable through the control unit, which can selectively actuate each locking element based on operational requirements. This dynamic control enables quick release when needed while maintaining secure locking during operation, reducing both assembly and disassembly time.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the tool holder is made easily removable, then assembly and disassembly become simple, but the tool holder may fall and break creating safety hazards

Engineering Contradiction:
Improveease of assemblyVSAvoidsafety during handling
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The guiding system with guiding rails and guiding slots is designed to automatically guide the tool holder into the correct position during assembly before the locking elements are engaged. This preliminary alignment action ensures the tool holder is properly positioned and secured, preventing accidental drops while maintaining ease of assembly through automatic guidance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The guiding system provides self-aligning functionality where the guiding rails and slots automatically ensure proper positioning of the tool holder during insertion. This self-service alignment mechanism eliminates the need for manual positioning adjustments and prevents misalignment that could lead to safety issues.

Inventive Principle:
Principle #25Self-service

3Reliability

If the tool holder is securely locked during operation, then safety is improved, but the assembly and disassembly process becomes more complex

Engineering Contradiction:
Improvesecure fastening during operationVSAvoidcomplexity of locking system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking system replaces complex mechanical locking mechanisms with a more sophisticated system that uses controllable locking elements actuated by a control unit. This substitution allows for secure locking during operation through automated control while simplifying the assembly and disassembly process through electronic actuation rather than manual mechanical operations.

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

4Manufacturing precision

If the tool holder alignment is manually adjusted repeatedly, then precise positioning can be achieved, but time is lost during each adjustment

Engineering Contradiction:
Improvealignment precisionVSAvoidtime for adjustments
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The guiding system with precisely engineered guiding rails and guiding slots performs the alignment action preliminarily during the assembly process. The tool holder is automatically guided into its correct position by these fixed precision guides, eliminating the need for repeated manual adjustments and saving time while maintaining high alignment precision.

Inventive Principle:
Principle #10Preliminary action
