Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trolleys for introducing dough blanks into multi-level ovens require significant manual effort and typically need two operators, limiting flexibility and efficiency in handling and placement.
Innovation Solution
A trolley with independent motor-driven cloth pullers for each storage level, allowing individual control and operation, along with a rechargeable battery for power and a control device for centralized or decentralized motor control, enabling single-operator operation and flexible handling of dough blanks under varying conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cloth-lifting devices are used to load dough blanks into multi-tiered ovens, then the equipment structure remains simple, but significant physical effort is required and two operators are always needed
Solution Approach 1:
The trolley is divided into multiple independent storage levels, each with its own motor-driven cloth puller. This segmentation allows each level to be operated independently, reducing the physical effort required per operator while maintaining a manageable overall structure.
Solution Approach 2:
The system transitions from static manual operation to dynamic motor-driven operation. Each storage level has an independently controllable motor that can be activated as needed, providing adaptable automation that reduces manual effort without requiring complete system complexity.
2Adaptability or versatility
If a common motor drive is used for all cloth removal devices, then the device structure is simplified, but flexibility in handling different baking conditions is reduced
Solution Approach 1:
The common motor drive is segmented into individual motors for each storage level. This allows each level to be controlled independently, enabling flexible response to different baking conditions (different times, temperatures) while keeping each motor unit relatively simple in structure.
Solution Approach 2:
Each storage level has its own motor with independent control, allowing local adaptation to specific baking requirements. Different levels can operate with different speeds, timings, or even be deactivated entirely based on local baking needs, providing versatility without requiring complete system redesign.
3Adaptability or versatility
If all cloth removal devices are moved simultaneously by a common drive, then the operation process is simplified, but the ability to respond to individual baking requirements is limited
Solution Approach 1:
The simultaneous movement system is segmented into independently controllable motors at each storage level. Operators can now select which levels to activate and when, allowing individual control for different baking requirements while maintaining straightforward motor operation without complex coordination mechanisms.
Solution Approach 2:
The system transitions from rigid simultaneous operation to dynamic selective operation. Each storage level can be activated independently based on real-time baking needs, providing adaptability while keeping the control mechanism simple through individual motor switches or basic control interfaces.
4Adaptability or versatility
If the entire trolley is pushed into the oven for loading, then the device structure remains fixed and simple, but flexibility in placement and handling is reduced
Solution Approach 1:
The fixed trolley structure is segmented into independently movable storage levels. Each level can be extended or retracted independently via its own motor, allowing flexible placement of dough blanks at different positions and times without requiring the entire trolley to be moved, while maintaining a relatively simple base structure.
Solution Approach 2:
The static trolley structure becomes dynamically adaptable. Storage levels can be extended or retracted as needed, providing placement flexibility for different oven configurations and baking requirements while keeping the overall device structure simple through modular design.
