Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current micro puree machines face difficulties in user feedback regarding correct bowl installation and blade assembly, leading to inefficiencies in the ice cream making process and impracticality for preparing non-dessert food products.
Innovation Solution
A micro puree machine equipped with a microswitch that interacts with projections on the bowl and a plunger of the lid and blade assembly to provide user feedback on correct installation and assembly through a cam member system, ensuring proper alignment and activation of the microswitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a micro puree machine uses a simple mechanical assembly without detection mechanisms, then the device complexity is reduced, but the user cannot discern when the bowl has been correctly installed or when the blade has been properly assembled
Solution Approach 1:
The patent implements feedback mechanisms through microswitches that detect the presence and correct positioning of the bowl and blade assembly. When the bowl is properly installed, a first microswitch is activated. When the blade is correctly assembled to the lid, a second microswitch is activated. These feedback signals provide real-time information to the user about the correctness of assembly, resolving the information loss problem without requiring complex detection systems.
Solution Approach 2:
The patent uses microswitches as intermediary detection elements between the mechanical components (bowl, lid, blade) and the control system. These microswitches act as mediators that convert mechanical positioning information into electrical signals, providing a simple yet effective way to detect assembly correctness without direct complex sensing of the mechanical components themselves.
2Ease of operation
If the machine provides detailed detection and feedback mechanisms for correct assembly, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The microswitch-based feedback system provides clear, binary information to the user about assembly correctness through the control interface. This simple feedback mechanism greatly improves ease of operation by eliminating uncertainty about proper assembly, while the underlying detection system remains mechanically simple and does not significantly increase overall device complexity.
3Measurement precision
If the machine uses a cam member system with multiple positions and plungers for detection, then the measurement precision of assembly correctness is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex electronic sensing systems with a mechanically-driven detection approach using cam members and plungers. The cam member's rotational position directly controls plunger engagement with microswitches, converting rotational position detection into simple mechanical contact detection. This substitution maintains high measurement precision for assembly correctness while keeping the detection system mechanically simple and reliable.

AI summary
A micro puree machine has a microswitch for interacting with projections on a bowl to alert the user that the bowl has been installed correctly to the machine housing. The microswitch also interacts with a plunger of a lid and blade assembly to alert the user that the blade has been properly assembled to the lid.
