Solution Overview

Problem

Conventional apparatuses for producing thermal-break profiles require multiple machines and manual intervention, leading to increased space requirements, installation costs, and reduced productivity due to the need for manual handling and potential damage to profile parts.

Innovation Solution

An apparatus that integrates knurling and bar insertion processes in a single unit, minimizing the need for separate machines and manual handling by using a transfer unit and assembly station with adjustable components to facilitate seamless processing of profile parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional apparatuses use multiple separate machines for knurling and bar insertion, then each machine can be specialized and simple in structure, but the apparatus requires increased space, has higher installation costs, and reduced productivity due to manual handling between stations

Engineering Contradiction:
Improvestructure of individual machineVSAvoidproductivity
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent combines multiple separate machines (knurling machine, bar insertion machine, transfer apparatus) into a single integrated apparatus. The working units are arranged along a common work path with automated transfer, eliminating the need for manual handling between separate stations while maintaining specialized functions for each operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated apparatus performs multiple functions (knurling, bar insertion, transfer, positioning) within a single system. The working units can process different profile parts sequentially along the work path, making the apparatus versatile for various thermal-break profile configurations.

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

2Ease of operation

If profile parts are moved manually between separate machines, then flexibility in operation is maintained, but the process requires several operators and increases the time required to complete the operation

Engineering Contradiction:
Improveflexibility in operationVSAvoidtime required to complete the operation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The apparatus enables self-service operation through automated transfer mechanisms. Profile parts are automatically transferred between working units along the work path without requiring manual intervention. The system manages its own material flow and positioning, reducing operator involvement to monitoring and initialization only.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The integrated apparatus enables continuous processing of profile parts through automated transfer and sequential operations. Multiple working units operate in sequence without interruption, eliminating the time losses associated with manual handling and positioning between separate machines.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of manufacture

If profile parts are moved and overturned between stations, then processing can be completed in separate machines, but the profile parts are subjected to shocks with consequent damage

Engineering Contradiction:
Improveprocessing in separate machinesVSAvoiddamage to profile parts
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

By integrating all processing operations within a single apparatus, the patent eliminates the need to move and overturn profile parts between separate machines. All working units operate along a common work path, keeping profile parts in stable positions throughout the manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The automated transfer apparatus acts as an intermediary between working units, providing controlled and stable transfer of profile parts. The transfer mechanism maintains proper orientation and positioning, preventing shocks and damage that would occur with manual handling and overturning.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If three separate working regions are provided for knurling and bar insertion, then each region can be optimized for its specific function, but adequate space must be set aside for the plant and costs increase

Engineering Contradiction:
Improveoptimization for specific functionVSAvoidspace required
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent arranges working units along a linear work path in a space-efficient configuration. Instead of providing separate horizontal areas for each machine, the operations are stacked or sequenced along a compact work path, reducing the overall footprint of the plant while maintaining functional optimization.

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

Solution Approach 2:

Multiple working units that would traditionally require separate locations are merged into a single integrated apparatus. The knurling unit, bar insertion unit, and transfer mechanisms share common infrastructure and workspace, significantly reducing the total space required while preserving the specialized functionality of each unit.

Inventive Principle:
Principle #5Merging (Combining)
