Innovation Solution
A modular, mobile food preparation device featuring a heating plate with an integrated filter and cover device that uses a multi-armed mechanism for parallel displacement, providing a compact and lightweight solution that includes a filter system for odor removal and a covering device that acts as a splash guard and extractor hood, with adjustable airflow and temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a covering device is used to prevent spills and odors, then food preparation safety is improved, but the device complexity increases
Solution Approach 1:
The patent combines the covering device, filter device, and exhaust air extraction system into a single integrated unit. The cover device (4) is operatively connected to the filter device (3), and the exhaust air flow channel integrates the covering device with the filter device, creating a unified system that reduces overall complexity while maintaining safety functions
Solution Approach 2:
The integrated device performs multiple functions simultaneously: the covering device prevents spills and odors, the filter device removes unwanted odors, and the exhaust air flow channel provides ventilation. This multi-functional design improves food preparation safety without requiring separate devices for each function
2Object-generated harmful factors
If a filter device is integrated to remove odors, then odor control is improved, but the device complexity increases
Solution Approach 1:
The filter device is merged with the covering device through operative connection, allowing odor filtration to be performed as part of the existing cover structure rather than as a separate component. The exhaust air flow channel further integrates these functions by routing exhaust air through both the covering and filtering systems
3Ease of operation
If a multi-armed mechanism is used for parallel displacement, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical displacement mechanisms with a parallel swivel arm mechanism that uses minimal moving parts. The multi-armed mechanism enables smooth parallel displacement of the covering device without requiring multiple separate actuators or complex linkages, reducing mechanical complexity while improving operability
