Rotatable Stator Turning Knob for Multiple Key Withdrawal Combinations
Solution Overview
Problem
Existing turning knobs with locks that allow multiple key withdrawals often require multiple stators to achieve different combinations, increasing manufacturing costs and assembly complexity.
Innovation Solution
A turning knob with a stator that can be positioned in various ways using complementary notches and flutes, allowing for multiple key withdrawal positions from a single stator, along with a sensitivity ring and lock-cover for assembly facilitation and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple stators are used to achieve different key withdrawal combinations, then the versatility of the turning knob is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple stator functions into a single stator by making the stator body itself rotatable relative to the body. This single stator can assume multiple positions (first position with first lateral opening, second position with second lateral opening) to provide different key withdrawal combinations, eliminating the need for multiple separate stators and reducing manufacturing complexity while maintaining versatility
2Adaptability or versatility
If multiple stators are used to achieve different key withdrawal combinations, then the versatility of the turning knob is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges the functionality of multiple stators into a single rotatable stator component. By making the stator rotatable and positionable at different angular orientations, one stator can provide multiple key withdrawal combinations that would otherwise require several separate stators, thereby reducing manufacturing costs through standardized production of a single component type
Solution Approach 2:
The stator is designed with multi-functionality, serving as both a stationary component and a rotatable element. The same stator structure can be positioned in different orientations to create various key withdrawal combinations, making it a universal component that replaces multiple specialized stators and simplifies manufacturing
3Adaptability or versatility
If multiple stators are used to achieve different key withdrawal combinations, then the versatility of the turning knob is improved, but the assembly complexity increases
Solution Approach 1:
The patent combines multiple stator assembly operations into a single assembly process. The rotatable stator is assembled once into the body, and then can be rotated to different positions during operation. This eliminates the need to assemble multiple separate stators, each requiring precise positioning, thereby reducing assembly complexity and the potential for assembly errors

AI summary
A turning knob with a lock for an electric circuit indicating a body for receiving a barrel rotating relative to a stator. The barrel includes springs receiving a key configured while rotating to take up at least two functional retained or released positions and having at one of its ends a shank configured to be actuated by rotating the key. The body has an inner cylindrical sleeve whereon the stator is urged to be positioned, the inner sleeve having a number of identical members for positioning the stator, each positioning member of the inner sleeve matching a corresponding positioning member of the stator, so as to select the position of the stator relative to the body.
