Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-power pulsed electromagnetic field (PEMF) systems face issues with electromagnetic energy leakage and inefficiency due to the generation of high-power signals in a base housing, which can be harmful and cumbersome for patients.
Innovation Solution
The system generates a low-power control signal in a base housing, which is received by applicators to locally produce high-power PEMF signals, reducing leakage by integrating a generator and electromagnetic energy shield within the applicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high-power signals are generated in the base housing, then the system can provide sufficient power for treatment, but electromagnetic energy leakage increases and patient comfort decreases
Solution Approach 1:
The system divides the high-power signal generation function from the base housing and relocates it to the applicator head. This segmentation allows the base to generate only low-power control signals while the applicator locally generates high-power PEMF signals, reducing electromagnetic leakage in the base and improving patient comfort.
Solution Approach 2:
The high-power signal generation capability is extracted from the base housing and integrated into the applicator. This extraction removes the source of electromagnetic leakage from the base, eliminating the harmful effect while preserving the therapeutic power output at the treatment site.
2Object-affected harmful factors
If the generator is integrated into the applicators, then electromagnetic field leakage is reduced, but the device complexity increases
Solution Approach 1:
The system is segmented into two functional modules: a base housing for control and a applicator for local signal generation. This segmentation distributes complexity across separate components, allowing each to be optimized independently while reducing overall electromagnetic interference.
Solution Approach 2:
A low-power control signal acts as an intermediary between the base housing and the applicator's high-power generation system. This intermediary signal enables remote control of the high-power PEMF generation without requiring physical proximity or direct high-power connections, simplifying the overall system architecture.
3Productivity
If high-power signals are generated locally in applicators, then treatment efficiency increases, but the weight of the applicator increases
Solution Approach 1:
The system segments the power generation function to the applicator head, enabling local high-power signal generation that improves treatment efficiency. The applicator weight increase is acceptable because the therapeutic benefits of localized high-power PEMF generation outweigh the minor inconvenience of additional weight.
