Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a base is fixed to the casing of the container, then the container provides a secure structure, but the shape becomes relatively complex which is difficult to produce in glass material
Solution Approach 1:
The container is divided into separate components: a glass envelope and a base that can be assembled together. This segmentation allows the glass envelope to maintain a simple, easy-to-manufacture shape while the base provides the necessary structural stability and functional features.
Solution Approach 2:
The base is designed to be assembled with the glass envelope through a coupling mechanism (screw thread connection), merging the structural benefits of a fixed base with the manufacturing simplicity of a separate glass component. This combination resolves the contradiction by integrating functions while maintaining manufacturing ease.
2Stability of the object's composition
If a base is fixed to the casing of the container, then the container provides structural stability, but access to the tool holder plate is made difficult requiring a specific tool
Solution Approach 1:
The base is designed as a separate, removable component that can be detached from the glass envelope. This segmentation provides structural stability when assembled while maintaining ease of access to the tool holder plate when the base is removed, eliminating the need for specific tools.
3Ease of manufacture
If the container is made with simple shape glass envelope and plastic base attached by gluing, then manufacturing is easier, but gaps at the junction are very difficult to clean and conducive to bacteria development
Solution Approach 1:
The base and glass envelope are designed as separate components that can be completely detached from each other. This segmentation eliminates permanent junctions and gaps where bacteria could develop, while maintaining manufacturing ease through simple assembly and disassembly operations.
Solution Approach 2:
The base is designed to be removable from the glass envelope, extracting the connection interface that would otherwise create hard-to-clean gaps. This allows complete access to all surfaces for cleaning while maintaining the manufacturing benefits of separate component production.
4Ease of operation
If the base is integral in translation with the envelope and rotatably mounted, then cleaning is facilitated by rotating the base to evacuate impurities, but the structure becomes more complex
Solution Approach 1:
The base is designed with rotational freedom relative to the glass envelope, allowing dynamic movement during cleaning operations. This dynamic capability facilitates easy evacuation of impurities by rotating the base, while the rotational mechanism is implemented through simple geometric features rather than complex mechanical components.

AI summary
The container (2) has a glass casing (4) comprising a lower end provided with an opening (41) to receive a removable tool-carrier plate (5). The plate is fixed, by rotation, on a coupling sleeve (42) surrounding the opening. An unremovable base of the casing includes a peripheral skirt (31) extending around the sleeve, where the base is made of plastic material. The base is connected in translation to the casing and mounted on the casing in a freely rotatable manner. The base freely rotates along a longitudinal axis of the sleeve, and includes driving fingers (55) for freely driving the plate. An independent claim is also included for an electric household culinary preparation appliance comprising a case provided with a receiving base plate.
