Innovation Solution
A system comprising a storage device for foldable flat elements, gripping means for precise extraction and positioning, a supporting and folding element for accurate folding, and housings for fixing the folded element to the bag, along with adjustable components for varying sizes and conveyor belt integration for efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a folded element is applied to bags of flexible material, then information reporting and consumer attraction are improved, but the application process becomes complex
Solution Approach 1:
The application system is divided into separate functional modules: a storage device for foldable elements, gripping means for extraction and positioning, a supporting and folding element for shaping, and housings for fixing to the bag. Each module performs a specific task, simplifying the overall complexity while maintaining effectiveness.
Solution Approach 2:
The foldable element is designed to be self-supporting during the application process. The supporting and folding element temporarily holds the foldable element in the correct position and shape, allowing the system to automate the application without complex positioning mechanisms.
2Productivity
If existing folding systems are used, then folding capability is provided, but speed and precision of application are not guaranteed
Solution Approach 1:
The foldable element is pre-prepared with folding lines and creases that define the exact folding position. The supporting and folding element is positioned beforehand to guide the folding process, ensuring both speed and precision without requiring complex real-time adjustment mechanisms.
Solution Approach 2:
The supporting and folding element acts as an intermediary between the foldable element and the bag. It temporarily holds the foldable element in the correct position and shape during folding, ensuring precision, then releases it for rapid attachment to the bag, improving overall application speed.
3Manufacturing precision
If the folding line is parallel to the upper end of the bag, then proper positioning is achieved, but the system requires precise alignment
Solution Approach 1:
The housing and supporting and folding element are designed with corresponding alignment features that automatically position the folding line parallel to the upper end of the bag. This equipotential design ensures proper alignment without requiring complex adjustment mechanisms, as the components naturally align when brought together.
