Pressure cooker equipped with a support and a lid which is movable with respect to said support
Solution Overview
Problem
Existing pressure cooking appliances face issues with sensors being permanently active, leading to potential malfunctions due to erroneous information, and existing sensor systems are not adaptable to various locking mechanisms, complicating construction and increasing costs.
Innovation Solution
A pressure cooking appliance with a cover sub-assembly that includes a support allowing the lid to move between unlocking and locking configurations, using first and second devices separated by a predetermined distance to deliver information and control signals, ensuring proper locking and operational status without unnecessary complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensors are permanently active to continuously monitor pressure cooker status, then information availability is improved, but reliability deteriorates due to erroneous information and malfunctions
Solution Approach 1:
The patent implements periodic action by using a control member that is manually actuated to periodically activate sensors only when needed (during locking/unlocking operations). This replaces continuous sensor operation with intermittent activation triggered by user action, ensuring information is collected at appropriate moments while avoiding erroneous readings from permanently active sensors.
Solution Approach 2:
The control member enables self-service by allowing the user to manually trigger sensor activation during locking/unlocking operations. The system serves itself by using the mechanical action of lid movement to activate the sensing function, eliminating the need for permanent electronic activation and reducing reliance on continuously powered sensors.
2Reliability
If additional control means are added to prevent malfunctioning, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the control function with the mechanical locking/unlocking mechanism. The control member is integrated into the lid assembly and uses the existing mechanical movement of the lid to activate sensors, combining structural and control functions into a single system rather than adding separate electronic control means.
Solution Approach 2:
The control member serves multiple functions: it acts as both the mechanical element for locking/unlocking the lid and the trigger for sensor activation. This multi-functional design eliminates the need for separate control systems while maintaining reliability through the unified mechanism.
3Measurement precision
If sensor systems are adapted to particular locking types, then measurement precision is improved, but adaptability deteriorates
Solution Approach 1:
The control member is designed with universal applicability to work with different locking mechanisms (bayonet, jaw, stirrup, flexible cover). The same basic control member structure can be adapted to various locking types without requiring completely different sensor systems, maintaining measurement precision through consistent activation methodology across different locking mechanisms.
Solution Approach 2:
The control member is designed to be dynamic and adaptable in its configuration. It can be positioned and configured to work with different locking mechanisms while maintaining the core function of triggering sensor activation, allowing the system to adapt to various locking types without sacrificing detection accuracy.
4Ease of operation
If locking mechanism movement is used to activate sensors, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system uses self-service by allowing the user's natural locking/unlocking action to automatically trigger sensor activation. The control member is positioned so that the user's manual operation of the lid directly activates the sensors without requiring separate control actions, making operation simple while incorporating the control function into the existing mechanical movement.
