Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for switches with rotary generators face issues due to complex gear mechanisms that are sensitive to foreign bodies and require isolation from the external environment, limiting their reliability and functionality.
Innovation Solution
A remote control device with a movable control member, a coaxially mounted stator and rotor, and a coupling mechanism involving a drive bar and attachment element that forces the rotor into a rest position, allowing for efficient rotation and energy generation without external power sources, using a transverse flux machine and spring return mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex gear mechanisms are used in the coupling mechanism, then the rotation of the rotor can be achieved, but the device becomes sensitive to foreign bodies and requires isolation from the external environment
Solution Approach 1:
The patent removes the complex gear transmission mechanism from the coupling between the control member and rotor. Instead, it directly couples the control member to the rotor through a simplified mechanical linkage, extracting the problematic intermediate gears that were sensitive to foreign bodies and required isolation.
Solution Approach 2:
Rather than using gears to transform the control member's movement into rotor rotation, the patent inverts the approach by directly linking the control member's linear or angular movement to the rotor's rotation through a simplified coupling mechanism, eliminating the need for complex intermediate transmission elements.
2Use of energy by moving object
If a rotary generator is used to generate electrical energy, then remote control signals can be transmitted, but the device requires a power source which complicates the structure
Solution Approach 1:
The control device generates its own electrical energy through the rotary generator, which is driven by the actuation of the control member itself. The mechanical energy from user interaction with the control member is directly converted to electrical energy by the generator, making the system self-powered without external batteries or power sources.
Solution Approach 2:
The patent replaces traditional electrical power sources (batteries, power supplies) with a mechanical-to-electrical energy conversion system. The rotary generator converts the mechanical energy from control member actuation into electrical energy, substituting a passive power source with an active energy conversion mechanism that eliminates the need for separate power supply components.
3Productivity
If the control member is actuated between two switching positions, then the rotor can be rotated to generate energy, but the rotor needs to be returned to a rest position which requires additional mechanisms
Solution Approach 1:
The patent combines the rotor return function with the control member's own movement. The control member's reciprocating motion between two switching positions directly drives the rotor forward, and the return movement of the control member automatically returns the rotor to its rest position through the coupling mechanism, merging the return function into the existing actuation cycle without separate return mechanisms.
Solution Approach 2:
The system utilizes periodic reciprocating motion of the control member between two switching positions to drive the rotor. Each complete cycle of the control member's movement (forward and return) generates a corresponding rotation cycle of the rotor, converting the periodic mechanical input into continuous energy generation through the generator.
