Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric brewing machines face challenges in ensuring a simple, ergonomic, and economical design while maintaining high safety, particularly in the handling and sealing of infusion accessories, which can lead to boiling water leakage and user burns.
Innovation Solution
An electric brewing machine with a movable gripping device that transitions between raised and lowered configurations, combined with a cover that presses against the gripping device to maintain it in the lowered position, ensuring easy handling and sealing, and includes features like steam evacuation circuits to prevent water spillage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gripping part extends outside the container to facilitate removal of the infusion accessory, then the ease of operation is improved, but the reliability deteriorates due to increased risk of boiling water flowing outside the container
Solution Approach 1:
The gripping device is made movable between a raised configuration (when lid is open) and a lowered configuration (when lid is closed). This dynamic adjustment allows the gripping part to extend outside the container during removal operations while retracting inside during sealed operation, thus resolving the contradiction between ease of operation and sealing reliability
2Reliability
If the gripping part is arranged entirely under the lid to prevent water leakage, then the reliability is improved, but the ease of operation deteriorates due to reduced accessibility for manipulation
Solution Approach 1:
The gripping device transitions from a static position to a dynamic one, allowing it to extend outward when needed for manipulation and retract when sealing is required. This dynamic behavior simultaneously achieves both reliability and ease of operation
3Object-affected harmful factors
If the gripping part is kept outside the water to prevent contamination and user burns, then the safety is improved, but the device complexity increases to achieve the movable configuration
Solution Approach 1:
A simple movable mechanism allows the gripping device to dynamically adjust its position, keeping it outside the water during operation for safety while avoiding the need for complex sealing structures or multiple components
Solution Approach 2:
The lid itself provides the pressing force to move the gripping device into the lowered configuration, utilizing the existing closing motion to achieve the safety function without additional actuators or complex mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a safe and efficient brewing experience by preventing water leakage and user burns, while maintaining a compact design and easy handling of infusion accessories.
Implementation Method 1
when the cover is in the closed position, the cover is configured to exert a pressing force against the gripping device
Implementation Method 2
the infusion accessory comprises a biasing device configured to elastically bias the gripping device towards the raised configuration
