Solution Overview
Problem
The existing receiving devices for capsule endoscopes face interference issues when wirelessly transmitting image signals in real-time, leading to increased power consumption and the need for larger size due to electromagnetic interference shielding, which complicates their portability and usability.
Innovation Solution
A receiving device with a receiving unit, a transmitting unit, and a control unit that separates the receiving and transmitting periods, allowing the device to wirelessly transmit image signals during non-receiving periods, thereby avoiding interference and reducing power consumption without the need for shielding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the receiving device wirelessly transmits image signals in real-time while receiving signals from the capsule endoscope, then the usability and portability are improved, but electromagnetic interference occurs between receiving and transmitting operations
Solution Approach 1:
The receiving device alternates between receiving operations and transmitting operations in periodic time slots. During receiving periods, the device receives image signals from the capsule endoscope. During transmitting periods, the device wirelessly transmits the received signals to the external display device. This periodic alternation prevents electromagnetic interference while maintaining real-time transmission capability.
2Object-affected harmful factors
If electromagnetic interference shielding is added to prevent interference between receiving and transmitting operations, then interference is reduced, but the device size and weight increase
Solution Approach 1:
Instead of using physical shielding structures that increase device size, the patent employs temporal separation of receiving and transmitting operations. The device switches between receiving mode and transmitting mode in periodic intervals, eliminating the need for electromagnetic shielding hardware and thus avoiding increased device volume and weight.
3Object-affected harmful factors
If electromagnetic shielding components are included to prevent interference, then interference protection is improved, but power consumption increases
Solution Approach 1:
The patent avoids using passive electromagnetic shielding materials that would continuously consume power or require active compensation systems. Instead, it uses temporal multiplexing where the device alternates between receiving and transmitting modes, eliminating the need for power-consuming shielding components and reducing overall power consumption.
