Solution Overview

Problem

Conventional dough production lines experience vibration issues due to the weight of motorized supporting structures, leading to inefficiencies and increased costs when trying to operate at higher speeds.

Innovation Solution

A line for dough production and treatment with a treatment device that moves in an alternating motion, supported by a fixed frame, using a motor that is not directly attached to the moving parts, allowing for reduced inertia and minimized vibrations, and featuring manipulator elements that can engage and rotate dough strips efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the supporting structure is motorized to enable high-speed movement of treatment elements, then productivity increases, but vibrations increase due to the weight of the motor and mechanical components

Engineering Contradiction:
Improvespeed of lineVSAvoidvibrations
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The treatment device is divided into modular treatment elements that can be independently positioned and actuated. Each treatment element can be controlled separately, allowing the system to process multiple dough pieces simultaneously at different positions along the conveyor, thereby increasing productivity without requiring a single heavy motorized structure to move the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A cable-driven actuation system serves as an intermediary mechanism between the fixed mounting structure and the treatment elements. The cables transmit force from fixed motors to the moving treatment elements, enabling precise positioning and movement without directly motorizing the supporting structure itself, thus avoiding vibrations while maintaining high-speed capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the supporting structure is made robust to support heavy motors and mechanical components, then reliability improves, but device complexity and cost increase

Engineering Contradiction:
Improveoperational stabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of mounting heavy motors on the moving supporting structure, the system inverts the arrangement by mounting motors on the fixed frame and using cable-driven actuation to move the treatment elements. This eliminates the need for a robust, complex motorized supporting structure while maintaining operational stability through the fixed mounting of heavy components.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The system replaces a direct mechanical motorized supporting structure with a cable-driven actuation system. This substitution eliminates the need for heavy motors and complex mechanical assemblies on the moving structure, reducing device complexity and cost while maintaining reliability through the simplicity of the cable-driven mechanism and fixed mounting of critical components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
