Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inductive energy transmission devices for linear transport systems lack the ability to quickly and dynamically adjust energy transfer from the carriage guide to the carriage, failing to provide separate and independent voltage supplies for control and load components efficiently.
Innovation Solution
The inductive energy transmission device features a secondary winding with separate control voltage and load voltage winding sections, allowing for independent voltage generation and adjustment, with the control voltage winding section providing a stable 24 V and the load voltage winding section capable of generating a higher 48 V, enabling flexible energy distribution and efficient operation of electrical consumers on the carriage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single secondary winding is used for both control voltage and load voltage, then the device complexity is reduced, but the ability to independently adjust and control different voltage outputs is lost
Solution Approach 1:
The secondary winding is divided into two separate winding sections: a control voltage winding section and a load voltage winding section. Each section can be independently adjusted to provide different voltage levels (e.g., 24V for control and 48V for loads), enabling independent control of different electrical consumers without requiring a single complex winding structure.
Solution Approach 2:
Different sections of the secondary winding are designed with different local properties - the control voltage winding section has specific turn ratios and conductor characteristics optimized for control electronics, while the load voltage winding section has different characteristics optimized for high-power loads. This allows each section to be tailored to its specific functional requirements.
2Ease of operation
If separate control voltage and load voltage winding sections are implemented, then independent voltage control and adaptability are improved, but the device complexity increases
Solution Approach 1:
The secondary winding is segmented into distinct control voltage and load voltage sections with separate adjustment mechanisms. This segmentation enables independent control of each voltage output through separate tap connections or adjustment means, allowing operators to optimize voltages for different operational conditions without affecting the other section.
Solution Approach 2:
The winding sections are designed with dynamic adjustment capabilities, allowing the voltage outputs to be changed during operation. Control voltage can be maintained at a stable level (e.g., 24V) while load voltage can be quickly adjusted or switched off as needed, providing operational flexibility and ease of control.
3Duration of action of stationary object
If energy transmission is continuously provided to the carriage, then the duration of energy supply is improved, but energy efficiency deteriorates when loads are not active
Solution Approach 1:
Instead of continuous energy transmission, the system uses periodic or on-demand energy transmission. The control voltage winding section can maintain a stable voltage for control electronics that need continuous power, while the load voltage winding section can be activated only when loads are present or active, reducing energy waste during periods when loads are not in use.
Solution Approach 2:
The energy transmission system is designed to be dynamic rather than static. The load voltage output can be quickly switched on or off based on load detection or control signals, while the control voltage remains continuously available. This dynamic control allows the system to adapt energy supply to actual needs, improving overall energy efficiency.
