A cooler comprising ice-cream making machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ice-cream making machines in freezer compartments face inefficiencies due to suboptimal positioning of the motor and transmission mechanism, leading to increased air temperature and prolonged freezing times, which hinder effective mixing and freezing processes.
Innovation Solution
A trigger mechanism is introduced that allows for easy detachment and reconnection of the chamber from the ice-cream making machine, enabling the shaft and mixer to be disconnected from the transmission mechanism, facilitating efficient removal and repositioning of the chamber within the freezer compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor and transmission mechanism are positioned in front of the cold air blowing ducts, then the structure is simplified, but the air temperature increases and freezing efficiency deteriorates
Solution Approach 1:
The ice-cream making machine is divided into separable components: the chamber can be detached from the housing, and the mixer can be disconnected from the shaft. This segmentation allows optimal positioning of each component - the chamber away from hot air paths and the motor/transmission mechanism in suitable locations without compromising freezing efficiency.
Solution Approach 2:
The trigger mechanism enables dynamic reconfiguration of the system. The chamber can be easily attached to and detached from the housing, and the mixer connected to or disconnected from the shaft, allowing the system to adapt its configuration based on operational requirements and thermal conditions.
2Stability of the object's composition
If the chamber is permanently fixed to the ice-cream making machine, then structural stability is improved, but ease of operation deteriorates
Solution Approach 1:
The system is segmented into detachable components connected through standardized interfaces. The chamber separates from the housing via the trigger mechanism, and the mixer disconnects from the shaft, enabling easy removal and cleaning while maintaining structural integrity during operation.
Solution Approach 2:
The trigger mechanism acts as an intermediary device that facilitates easy detachment. By actuating the trigger, the chamber can be quickly released from the housing without requiring forceful manipulation or complex disassembly procedures.
3Productivity
If the mixer remains continuously connected to the shaft, then motion transmission efficiency is improved, but ease of operation deteriorates
Solution Approach 1:
The connection between the mixer and shaft is made dynamic rather than fixed. The trigger mechanism enables the mixer to be connected to the shaft during operation for efficient motion transmission, and easily disconnected when the chamber needs to be removed or cleaned, providing operational flexibility.
Solution Approach 2:
The trigger mechanism is designed to be actuated by the user through a simple motion, enabling self-service detachment of the mixer from the shaft without requiring external tools or assistance, thereby maintaining ease of operation while preserving motion transmission efficiency during use.
