Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and high cost of multipurpose machines for producing thermoplastic containers, along with the risk of human error in programming, are exacerbated by the need for multiple operating parameters and databases that are difficult to update, especially when manufacturing containers for different liquid types or temperatures.
Innovation Solution
A method involving a two-dimensional barcode on each mold that stores compatible operating parameter values, allowing an optical reader to automatically transmit these values to the electronic control unit, limiting parameter choices to compatible settings and eliminating the need for additional databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multipurpose machine is used to produce many types of containers, then productivity and versatility are improved, but device complexity and programming difficulty increase
Solution Approach 1:
The mold carries its own identification data (barcode or RFID tag) that automatically provides the control unit with the necessary forming parameters when the mold is installed. This self-service approach eliminates the need for complex manual programming by the operator, as the system automatically retrieves and applies the correct parameters stored with each mold.
Solution Approach 2:
The forming parameters are copied and stored on portable data carriers (barcodes or RFID tags) attached to each mold. This allows the parameters to be transferred automatically from the mold's data carrier to the machine's control system, replacing complex database management and manual parameter entry while maintaining versatility across different container types.
2Reliability
If predefined recipes are used to limit human error, then reliability is improved, but adaptability and fine-tuning capability deteriorate
Solution Approach 1:
The system dynamically adapts the forming parameters based on the specific mold installed. Rather than using fixed predefined recipes, the control unit automatically retrieves and applies parameters specific to each mold type, allowing fine-tuned optimization for each container configuration while maintaining reliability through automated parameter selection.
Solution Approach 2:
Each mold carries its own optimized parameters in the form of identification data, enabling the system to automatically select the correct parameters for each mold without relying on predefined recipes. This self-service mechanism ensures both reliability (by preventing human selection errors) and adaptability (by providing mold-specific optimized parameters).
3Adaptability or versatility
If a complex database is used to store and manage operating parameters, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The centralized database is segmented and distributed to individual molds through portable data carriers (barcodes or RFID tags). Each mold carries its own parameter set locally, eliminating the need for a complex centralized database system while maintaining the ability to manage multiple container types through decentralized parameter storage.
Solution Approach 2:
The forming parameters are copied from the centralized database to portable data carriers attached to each mold. This copying process simplifies the system architecture by distributing data storage to the point of use, eliminating complex database management requirements while maintaining full adaptability across different container types.
4Adaptability or versatility
If manual programming is used to select operating parameters, then adaptability is improved, but reliability deteriorates due to human error
Solution Approach 1:
The mold provides its own identification data through barcodes or RFID tags, enabling the control unit to automatically retrieve and apply the correct forming parameters without human intervention. This eliminates human error in parameter selection while maintaining adaptability through mold-specific parameter identification.
Solution Approach 2:
The manual mechanical process of parameter selection and input is replaced with an automated optical or electromagnetic reading system (barcode scanner or RFID reader). This substitution eliminates human error in parameter selection while maintaining the ability to adapt to different container types through automated parameter retrieval.
