Food Processor Locking Device with Detection-Verified Securing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processor locking devices often fail to ensure a secure and accurate assembly of the vessel and lid, leading to potential leakage during food preparation, as they lack a reliable mechanism to prevent rotational play and ensure correct installation of the securing element.
Innovation Solution
A locking device with a securing element that secures the non-rotatable connection between the locking element and lever, utilizing a detection device to verify the correct assembly by measuring the position of the locking lever, and incorporating a securing element in the force flow of the actuator to prevent play and ensure proper alignment, along with an acoustic or optical sensor to confirm correct installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device with locking element and locking lever is used, then the vessel and lid can be connected, but rotational play and incorrect assembly prevent secure connection
Solution Approach 1:
The patent applies preliminary action by providing a detection device that checks the assembly state of the locking element and locking lever before the locking operation is completed. The detection device verifies whether the locking lever is in the correct position and whether the locking element is properly engaged, preventing incorrect assembly from compromising the secure connection.
Solution Approach 2:
The patent implements feedback through a detection device that monitors the position and assembly state of the locking components. The detection device provides information about whether the locking lever and locking element are correctly assembled, allowing the system to verify proper connection before completing the locking operation, thus ensuring reliability while maintaining manufacturing precision.
2Ease of operation
If locking element and locking lever are rotatably connected for assembly flexibility, then installation is easier, but rotational play prevents firm connection
Solution Approach 1:
The patent applies preliminary action by using the detection device to verify the assembly state before final locking. The detection device checks whether the locking lever has been properly positioned and whether the locking element is correctly engaged, ensuring that the rotational flexibility during installation does not compromise the stability of the final connection.
Solution Approach 2:
The patent implements feedback through continuous monitoring of the locking lever position and locking element engagement state. The detection device provides real-time information about the assembly stability, allowing the system to confirm that the rotatable connection has been properly secured before completing the locking operation, thus maintaining both ease of installation and connection stability.
3Device complexity
If no detection device is used, then the device complexity is reduced, but incorrect assembly cannot be detected
Solution Approach 1:
The patent implements feedback through a detection device that monitors the assembly state of the locking components. The detection device provides information about whether the locking lever and locking element are correctly assembled, allowing the system to verify proper connection. This feedback mechanism ensures reliability while adding only the necessary complexity for assembly verification.
Solution Approach 2:
The patent applies self-service by enabling the locking device to automatically verify its own assembly state through the detection device. The detection device monitors the position and engagement of the locking components, allowing the system to self-verify correct assembly without external intervention, thus maintaining reliability while minimizing the complexity of external verification systems.

AI summary
The invention relates to a food processor, in particular a blender, with a housing (2) on which a vessel can be arranged, the housing (2) having a locking device for locking the vessel to a lid, the locking device having at least one locking element (3) a locking lever (4) which can be connected in a rotationally fixed manner to the locking element (3) and an actuator (5), the locking lever (4) and the actuator (5) being operatively connected in such a way that the locking lever (4) moves as a result of actuation of the actuator ( 5) can be moved from an open position to a locked position and vice versa, in particular can be pivoted as a result of actuation of the actuator (5). To ensure proper assembly of the locking device, it is proposed that the locking element (3) and the locking lever (4) can be moved into a form-fitting position by rotating them relative to one another, and that the form-fitting position be secured by a separately inserted securing element (7), which is in the flow of force from the actuator (5) applied locking force is fixable.
