Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable simplified image display apparatuses struggle with determining the strength of radio signals from capsule endoscopes, especially in environments with blood flow, leading to weak signal transmission and difficulty in real-time observation, and lack effective measures for identifying abnormal capsule endoscopes with weak output before examination.
Innovation Solution
A portable simplified image display apparatus with an integral antenna that detects and displays the strength of radio signals from capsule endoscopes, using a detector and notifying unit to visually, audibly, or through light patterns indicate signal strength, and includes a built-in memory for storing image data, allowing for real-time observation and identification of abnormal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are distributed and fixedly arranged on the body surface to receive signals from the capsule endoscope, then signal reception coverage is improved, but signal strength remains weak in areas with blood flow blocking transmission
Solution Approach 1:
The patent makes the receiving antenna movable rather than fixed, allowing it to be repositioned to find optimal signal reception locations. The antenna can be moved along the body surface to areas where blood flow does not block the radio signal transmission, thereby maintaining strong signal strength while ensuring reliable reception.
Solution Approach 2:
The patent incorporates a signal strength detector that provides real-time feedback on the received signal strength. This feedback mechanism allows the system to monitor signal quality and determine when the antenna needs to be repositioned to maintain optimal reception, enabling adaptive adjustment based on actual transmission conditions.
2Ease of operation
If a portable simplified image display apparatus is made compact for portability, then ease of carrying is improved, but the display unit size and signal processing capability are reduced
Solution Approach 1:
The patent extracts the signal processing function from the portable display apparatus and assigns it to the receiving device. This allows the portable apparatus to be kept compact while still achieving full image display capability, as the receiving device handles the computationally intensive signal processing tasks.
Solution Approach 2:
The receiving device serves multiple functions: it performs signal reception, signal processing, and can also display images. This multi-functionality reduces the need for separate dedicated components in the portable apparatus, allowing for a more compact design while maintaining full functionality.
3Productivity
If real-time image display is implemented during capsule endoscope examination, then diagnostic efficiency is improved, but the system complexity and cost increase
Solution Approach 1:
The patent combines the real-time display function with the existing receiving device that is already being used for capsule endoscope examinations. By integrating these functions into a single system rather than adding separate equipment, the solution achieves real-time diagnostic capability while minimizing the increase in system complexity and cost.
4Adaptability or versatility
If the capsule endoscope transmits signals through blood-containing internal organs, then comprehensive examination coverage is improved, but signal transmission strength deteriorates due to blood flow interference
Solution Approach 1:
The movable antenna design allows the receiving device to dynamically adapt to different examination scenarios. When examining areas with significant blood flow, the antenna can be repositioned to locations where signal transmission is less blocked, thereby maintaining adequate signal strength while preserving comprehensive examination coverage.

AI summary
A portable simplified image display apparatus and a receiving system are provided, which can sensuously know the state of received strength of radio signals transmitted from a body-insertable apparatus, in either case of before examination or during examination. A viewer (7) includes a detector that detects received strength of a radio signal transmitted from a capsule endoscope (2) and a notifying unit that notifies the detected state of received strength in a display pattern such as a picture display of a capsule (41). Therefore, in either case of before examination or during examination, the state of received strength of radio signals transmitted from the capsule endoscope (2) can be sensuously known according to the notification result of the state of received strength. If it is during examination, supplementary observation can be performed based on an excellent received image by searching a site having strong received strength, thereby enabling contribution to satisfactory examination.
