Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry-forming methods for cellulose products face challenges in efficiently removing the formed products from the forming mould without the need for costly and complex mechanical devices, which complicates the process and increases time consumption.
Innovation Solution
The use of an ejection element attached to the forming mould, configured as a resilient protruding body that expands from a compressed state to a non-compressed state to separate the formed cellulose products from the mould, eliminating the need for mechanical removal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical removal devices are used to remove cellulose products from the forming mould, then the cellulose products can be removed, but the device complexity and cost increase significantly
Solution Approach 1:
The forming mould is designed with an integrated ejection element that enables self-ejection of the formed cellulose product. The resilient protruding body automatically expands upon springing of the mould to push the product off the mould surface, eliminating the need for separate mechanical removal devices and making the system self-sufficient for product ejection
Solution Approach 2:
The ejection function is extracted from complex mechanical removal devices and integrated directly into the forming mould structure as a simple resilient protruding body. This extraction simplifies the overall system by removing the need for separate ejection mechanisms while maintaining effective product removal capability
2Ease of operation
If mechanical removal devices are used to remove cellulose products, then complete removal is achieved, but the production time increases due to complicated operation
Solution Approach 1:
The ejection element remains in contact with the cellulose product throughout the forming process, continuously applying ejection force as the mould springs open. This continuous action ensures complete product removal without interruption or additional操作步骤, reducing the time loss associated with separate removal operations
Solution Approach 2:
The forming mould automatically ejects the product through its integrated resilient protruding body when the mould springs open, eliminating the need for manual or mechanical intervention in the removal process. This self-ejection capability significantly reduces the time required for product removal compared to complicated mechanical devices
3Device complexity
If simple ejection elements are used, then device complexity is reduced, but the ejection effectiveness may be insufficient
Solution Approach 1:
The ejection element is designed as a resilient protruding body that dynamically changes its state from compressed during forming to expanded during ejection. This dynamic behavior allows the simple ejection element to generate sufficient ejection force reliably when the mould springs open, compensating for its structural simplicity
Solution Approach 2:
The resilient protruding body utilizes changes in its physical state (compression to expansion) driven by the mould springing action. This parameter change enables the simple ejection element to generate the necessary force for effective product ejection without requiring complex mechanical structures

Function Achieved in This Case
The ejection element facilitates efficient and fast removal of cellulose products from the mould, ensuring they are not stuck, allowing for a simpler and more efficient production process.
Implementation Method 1
The ejection element is arranged as a resilient protruding body extending in a pressing direction of the forming mould relative to a surrounding surface of the forming mould in a non-compressed state. The ejection element is configured for separating the formed cellulose products and/or the residual parts of the cellulose blank structure from the forming mould upon expansion of the ejection element from a compressed state to the non-compressed state
