Solution Overview

Problem

Existing dough processing devices struggle to efficiently separate and enlarge the distance between dough pieces, leading to potential deformation and increased maintenance costs due to complex mechanisms.

Innovation Solution

A device comprising a first and second conveyor belt system, where the second belt operates at a higher speed than the first, and a rotating wave with radially positioned driver elements that move dough pieces from the first to the second conveyor belt using gravity and own weight, minimizing deformation and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If pressure rollers or rotating shafts are used to move dough pieces between conveyor belts, then the dough pieces can be transferred from the first conveyor belt to the second conveyor belt, but the complexity of the device increases and maintenance costs increase

Engineering Contradiction:
Improvedough piece separation efficiencyVSAvoidmechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of dough piece transfer by using only the driver elements on the rotating shaft, eliminating the need for complex pressure rollers or additional conveyor belt systems. The driver elements directly engage with the dough pieces to push them onto the second conveyor belt, simplifying the overall mechanism while maintaining separation efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a rotating shaft with driver elements that dynamically engage and disengage with the dough pieces during rotation. This dynamic mechanism allows for efficient transfer of dough pieces without requiring complex stationary or multi-component systems, reducing device complexity while maintaining productivity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If complex mechanisms are used to separate dough pieces, then the separation function is achieved, but maintenance costs and operational complexity increase

Engineering Contradiction:
Improveseparation reliabilityVSAvoidmaintenance ease
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent segments the separation mechanism into simple, independent driver elements mounted on the rotating shaft. Each driver element is a separate, easily replaceable component that can be independently maintained or replaced without affecting the entire system, significantly improving ease of repair while maintaining separation reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotating shaft with driver elements operates using its own rotational motion to transfer dough pieces, eliminating the need for additional complex mechanisms or external assistance. The system serves itself by using the rotational energy already present in the conveyor belt movement, reducing maintenance requirements and improving operational reliability.

Inventive Principle:
Principle #25Self-service

3Productivity

If force is applied to move dough pieces from the first conveyor belt to the second conveyor belt, then the transfer is achieved, but the risk of dough deformation increases

Engineering Contradiction:
Improveconveying speedVSAvoiddough deformation risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies only the necessary minimal force through the driver elements to push the dough pieces onto the second conveyor belt. The driver elements make contact with the dough pieces just enough to transfer them, avoiding excessive force that could cause deformation. This partial action approach maintains conveying speed while minimizing harmful effects on the dough.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent changes the parameter of force application by using a rotating shaft mechanism that distributes the transfer force over time and space. The rotational motion allows for gradual, controlled engagement with the dough pieces rather than sudden, high-force contact, reducing the risk of deformation while maintaining efficient transfer.

Inventive Principle:
Principle #35Parameter changes
