Locking mechanism for coffee machine, and working method therefor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee machine locking mechanisms either lack convenience in operation or sealing performance, failing to meet consumer requirements.
Innovation Solution
A locking mechanism that operates by lifting or pressing an operating plate to move a pressing block up and down, which in turn rotates a rotation locking disk via an oblique guiding connection, engaging or misaligning locking blocks with grooves for locking and unlocking, and applying pressure for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is provided to prevent water leakage, then reliability is improved, but device complexity increases due to additional locking arms and sensors
Solution Approach 1:
The patent combines multiple locking arms into a single integrated locking mechanism that can simultaneously engage with multiple lugs on the water tank. This merging approach maintains the reliability of preventing water leakage while reducing the number of separate components and simplifying the overall structure compared to having independent locking arms for each corner.
Solution Approach 2:
The locking mechanism is designed to perform multiple functions: it not only prevents water leakage by securing the water tank but also enables the coffee machine to detect the water tank's presence and orientation through integrated sensors. This multi-functionality reduces the need for separate detection mechanisms, thereby simplifying the overall device complexity.
2Device complexity
If the water tank is not fixed firmly, then device complexity is reduced, but productivity decreases due to frequent disconnections during operation
Solution Approach 1:
The locking mechanism incorporates a sensor-based detection system that dynamically monitors the water tank's position and connection status. When the water tank is properly locked, the sensor confirms the connection and enables brewing operations. This dynamic detection ensures firm fixation during operation to maintain productivity while allowing easy installation and removal when needed, balancing complexity and operational continuity.
3Ease of manufacture
If simple mounting structure is used, then ease of manufacture is improved, but reliability worsens due to water leakage and disconnection issues
Solution Approach 1:
The locking mechanism is divided into modular components including locking arms, lugs, and sensors that can be manufactured separately and assembled. This segmentation allows each component to be produced using simple, standardized processes while the assembled mechanism provides reliable connection stability, preventing both water leakage and accidental disconnections during brewing operations.

AI summary
Disclosed are a locking mechanism for a coffee machine, and a working method therefor. The locking mechanism for a coffee machine comprises an operation plate, a gland assembly and a supporting seat, wherein the gland assembly comprises a pressing block, a rotary lock disk and a guide column; the operation plate is connected to the pressing block; the guide column is longitudinally arranged; the pressing block is in sliding fit with the guide column; a guide connecting position, which is arranged, in an inclined manner, on the rotary lock disk; the pressing block drives the rotary lock disk to rotate by means of the guide connecting position; a lock block is arranged on the rotary lock disk; and a lock groove fitted to the lock block is provided in the supporting seat. The locking mechanism can effectively achieve a locking function, is convenient to operate, has a good sealing performance, and can better meet use requirements of consumers.
