Drink Maker Lever Coupling to Reduce Mixing Vessel Installation Effort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frozen drink makers require significant user effort to install and uninstall the mixing vessel, straining the plastic and making the process challenging.
Innovation Solution
A lever mechanism that allows for easy coupling and uncoupling of the mixing vessel to the upper housing section using minimal force, facilitated by a flexible seal and a cam feature, enabling one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional mixing vessel installation method is used, then the mixing vessel can be securely installed, but significant user effort is required and the plastic housing is strained
Solution Approach 1:
The patent applies a spring-loaded lever mechanism that dynamically adjusts during the installation process. When the lever is actuated, the spring provides progressive force to push the mixing vessel into the housing, maintaining secure installation while requiring minimal initial user effort. The dynamic spring force adapts to the resistance encountered during installation.
Solution Approach 2:
The lever acts as an intermediary mechanical element between the user and the mixing vessel. Instead of directly applying force to the vessel, the user operates the lever, which then translates this into the necessary installation force through its mechanical advantage and spring-assisted motion, reducing strain on the plastic housing.
2Reliability
If a secure coupling mechanism is used, then the mixing vessel is firmly attached, but the installation and uninstallation process becomes difficult
Solution Approach 1:
The spring-loaded lever creates a dynamic coupling system. During installation, the spring-loaded motion guides the vessel into place and secures it firmly. During uninstallation, the same spring mechanism, when activated, provides the force needed to release the coupling, making both operations easier while maintaining firm attachment during normal use.
Solution Approach 2:
The lever mechanism operates through periodic cycles of engagement and disengagement. Each actuation of the lever represents a periodic action that either secures or releases the mixing vessel, allowing the system to transition between firmly attached and easily removable states as needed.

AI summary
A drink maker is described that includes a housing, a mixing vessel configured to be removably coupled to the housing and receive a drink product, a dasher configured to mix the drink product within the mixing vessel, a drive motor configured to drive the dasher, and a controller. The controller is configured to detect an unsafe condition associated with the drink maker and, in response to detection of the unsafe condition, execute at least one control action comprising at least one of: alerting a user of the drink maker, deactivating the drive motor, preventing activation of the drive motor, or any combination thereof.
