Solution Overview

Problem

The existing receiving apparatus for capsule endoscopes risks losing valuable image data and damaging the portable recording medium due to accidental ejection during long examination periods, as there is no effective mechanism to prevent erroneous ejection during recording operations.

Innovation Solution

Incorporating an in-operation detector, ejection operation detector, and a warning unit that alerts the user before attempting to eject the portable recording medium, ensuring that the ejection operation is not performed during recording, thus preventing data loss and medium damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the portable recording medium is made detachable from the receiver, then the ease of operation is improved, but the reliability deteriorates due to risk of erroneous ejection during recording

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of ejection operations and issues warnings before the actual ejection occurs. The ejection operation detector detects when a user attempts to eject the portable recording medium, and the warning unit provides advance notification, allowing the user to cancel the ejection operation before data loss occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by detecting ejection operations and providing warning signals to the user. The ejection operation detector continuously monitors for ejection attempts, and when detected, the warning unit provides feedback to the user through visual or audible signals, enabling the user to respond appropriately and prevent erroneous ejection.

Inventive Principle:
Principle #23Feedback

2Reliability

If a lock mechanism is strengthened to prevent ejection during recording, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces mechanical lock mechanisms with an electronic detection and warning system. Instead of using physical locks or complex mechanical interlocks, the invention uses an ejection operation detector to sense ejection attempts and a warning unit to provide electronic warnings, significantly reducing mechanical complexity while maintaining reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system provides self-service by automatically detecting ejection operations and issuing warnings without requiring external intervention or complex control mechanisms. The ejection operation detector and warning unit work autonomously to prevent erroneous ejection, eliminating the need for manual lock management or complex mechanical safety systems.

Inventive Principle:
Principle #25Self-service

AI summary

A receiving apparatus for receiving a radio signal through an antenna. The radio signal is transmitted by a moving transmitting apparatus and has a frame configuration which includes at least a main information portion that includes information main part based on an image signal and an added portion that includes synchronization information and parameter information specific to the transmitting apparatus. The receiving apparatus includes a detecting unit that is configured to detect, from the received radio signal, an arrangement position of the parameter information in a frame configuration in which an error-correcting code is added immediately after the parameter information to be transmitted in a predetermined arrangement position of the frame configuration. A parameter information error correcting unit is configured to perform error correction on the parameter information with the error-correcting code that is added immediately after the detected arrangement position of the parameter information. An image processing unit is configured to perform image processing on the image signal of the main information portion using the corrected parameter information.
