Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing filled dough products face challenges in achieving reliable adhesion between dough and fillings, particularly with dimensionally stable or pasty fillings, leading to inefficiencies and disruptions in the production process.
Innovation Solution
A device featuring a conveyor system with tethers and a folding device equipped with pivotable hooks that engage with the dough to enhance wrapping reliability, combined with an adjustable wrapping element and a suction device to ensure secure adhesion and prevent filling displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing device is used to create adhesion between dough and filling, then adhesion is improved, but reliable adhesion is not always achieved and additional measures like wetting are required
Solution Approach 1:
A suction device is introduced as an intermediary mechanism between the dough and filling. The suction device creates a vacuum that actively holds the filling in place on the dough, providing more reliable adhesion than pressing alone without requiring additional wetting measures. This resolves the contradiction by achieving reliable adhesion through a dedicated vacuum holding mechanism rather than complex multi-step processes.
Solution Approach 2:
The mechanical pressing action is replaced or supplemented by a suction-based holding system. Instead of relying solely on mechanical pressure to create adhesion, the system uses vacuum suction to hold the filling securely on the dough, providing more consistent and reliable adhesion without requiring additional wetting steps.
2Adaptability or versatility
If swivel arms are used as winding components, then wrapping capability is improved, but pasty filling material is smeared and filling is displaced
Solution Approach 1:
The suction device acts as an intermediary that holds the filling securely in place during the wrapping process. By creating a vacuum that firmly holds the filling on the dough, the system prevents the filling from being smeared or displaced by the winding components, while still maintaining the ability to wrap various types of fillings.
Solution Approach 2:
The suction device is activated before and during the wrapping process to pre-position and secure the filling on the dough. This preliminary action ensures the filling is firmly held in place before the winding components make contact, preventing smearing and displacement during the wrapping operation.
3Object-generated harmful factors
If winding components are spaced apart transversely, then filling smearing is reduced, but dimensionally stable fillings are displaced or pushed down
Solution Approach 1:
The suction device serves as an intermediary that holds the filling securely in place regardless of the spacing between winding components. By creating a vacuum that firmly anchors the filling to the dough, the system maintains filling position stability even when winding components are spaced apart to prevent smearing, eliminating the trade-off between these two parameters.
4Ease of operation
If dough is turned upwards on its front edge, then wrapping is enabled, but filling goods are displaced or rolled away
Solution Approach 1:
The suction device acts as an intermediary that holds the filling securely in place during the dough turning and wrapping process. By creating a vacuum that firmly anchors the filling to the dough, the system enables the dough to be turned upwards for wrapping without causing the filling to be displaced or rolled away, resolving the contradiction between wrapping enablement and filling position stability.
