Inductive Feed System for Lyophilizer Slider Energy Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy feed systems for lyophilization machines in the pharmaceutical sector are bulky, costly, and generate dust, fumes, or magnetic forces, complicating maintenance and cleaning, and creating interference with lyophilized substances, while energy accumulation means require recharging and increase production costs.
Innovation Solution
A static energy feed system that supplies electric energy to sliders within the lyophilization chamber using insulated pathways or wireless induction coils, allowing for continuous energy transfer without mobile energy sources, reducing interference and simplifying maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If mechanical cables or electric cables are used to supply power to sliders, then energy can be transmitted to moving parts, but dust, fumes, magnetic forces, and cleaning complexity are generated
Solution Approach 1:
The patent replaces mechanical cable-based power transmission with a magnetic field-based inductive coupling system. Primary coils are mounted on the stationary slider support structure, while secondary coils are mounted on the movable slider. Electrical energy is transmitted wirelessly through magnetic induction between these coils, eliminating the need for physical cable connections that generate dust, fumes, and magnetic interference.
2Use of energy by moving object
If energy accumulation means are installed on board the slider, then mobile energy supply is achieved, but system complexity and maintenance requirements increase
Solution Approach 1:
The patent extracts the energy accumulation function from the movable slider and relocates it to the stationary support structure. The primary coils mounted on the stationary structure serve as the energy source, eliminating the need for batteries or capacitors on the slider itself. This extraction simplifies the moving components while maintaining continuous energy supply through inductive coupling.
3Ease of operation
If command and control means are interfaced with cables, then communication is established, but electromagnetic disturbances are created
Solution Approach 1:
The patent replaces cable-based communication with wireless communication using antennas mounted on the slider and corresponding receivers on the stationary structure. This substitution eliminates the electromagnetic interference that would be generated by cable connections while maintaining full communication capability for controlling slider operations.
