Electric brewing machine comprising an infusion accessory equipped with a gripping member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric brewing machines face challenges in balancing ergonomic design, safety, and contamination prevention, particularly with infusion accessories that have gripping parts located under the lid, which can lead to burning risks and water spillage.
Innovation Solution
The electric brewing machine features a gripping member located outside the container, a sealing device with offset annular seals, and a steam evacuation system to prevent water and steam spillage, ensuring safety and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the gripping part is arranged entirely under the lid in the internal volume, then contamination of water is limited and burning risk is reduced, but the height of the container must be increased or the gripping part size reduced, affecting ergonomics
Solution Approach 1:
The gripping member is divided into two functional parts: a gripping portion for user manipulation and a connecting portion that extends into the internal volume. This segmentation allows the gripping portion to remain outside the water (reducing burning risk) while the connecting portion provides structural connection, resolving the contradiction between safety and ergonomics
Solution Approach 2:
The gripping member extends in a vertical dimension from the infusion accessory body through the lid to the external environment. This vertical arrangement allows the gripping portion to be accessible from above while maintaining connection to the infusion accessory, eliminating the need to increase container height while preserving ergonomic access
2Object-affected harmful factors
If the gripping part is kept outside the water to prevent burning and contamination, then safety is improved, but the structure becomes more complex requiring a lid that partially covers the infusion accessory
Solution Approach 1:
The lid serves multiple functions: it closes the container opening, partially covers the infusion accessory for aesthetic and protective purposes, and provides a mounting surface for the gripping member. This multi-functionality reduces the need for additional separate components, mitigating the complexity increase
Solution Approach 2:
The gripping member is integrated with the lid structure, where the connecting portion of the gripping member extends through or alongside the lid. This merging of functions allows the lid to both cover the container and support the gripping mechanism, reducing overall structural complexity
3Ease of operation
If the gripping member extends between the lid and container, then the gripping part can be accessed from outside, but water spillage risk increases
Solution Approach 1:
The connecting portion of the gripping member acts as an intermediary element that extends through the lid structure. This intermediary design allows the gripping portion to be externally accessible while the connection to the infusion accessory is maintained through the sealed lid, preventing direct water exposure
Solution Approach 2:
The gripping portion is extracted from the internal water volume and positioned externally through the lid. This extraction removes the user's hand and gripping surface from the hazardous water environment while maintaining functional connection through the lid barrier
