Implantable Instrument Antenna Positioning for Stable Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable instruments with wireless communication capabilities often experience unstable communication due to the display section blocking radio waves, which affects the reliability of wireless communication.
Innovation Solution
The design includes a touch panel display with a fixing member and antennas positioned to avoid overlap in the thickness direction, allowing for stable wireless communication by ensuring the antennas are not shielded by the fixing member, and are disposed between the first and second housings to facilitate unobstructed radio wave transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication section is disposed between the wall surface and the display section, then the display section blocks radio waves for wireless communication, but this arrangement is compact and easy to manufacture
Solution Approach 1:
The patent transitions from a two-dimensional layout where the antenna is positioned between the wall and display section to a three-dimensional arrangement where the antenna is disposed on the rear surface of the housing. This dimensional change allows the antenna to be positioned outside the blocking path of the display section while maintaining a compact overall structure, thereby resolving the contradiction between communication reliability and device complexity
2Ease of manufacture
If the display section is positioned to block radio waves, then the structure is simplified, but wireless communication becomes unstable
Solution Approach 1:
The patent extracts the antenna from the internal space between the wall and display section and positions it on the rear surface of the housing. This extraction removes the source of the blocking problem while maintaining the simplified structural arrangement of the display section, thereby resolving the contradiction between ease of manufacture and communication reliability

AI summary
An implantable instrument includes a first housing having a front surface having an opening, a second housing having at least part embedded in a building member, a touch panel display, four antennas for wireless communication, and a control board. The second housing is disposed to face a rear surface of the first housing to form an accommodation space between the first housing and the second housing. The touch panel display includes: a display section having a plate-like shape; and a fixing member having a plate-like shape, being disposed to face a rear surface of the display section, and fixing the display section to the first housing. The touch pane display is disposed in the accommodation space so that the display section is visually perceivable through an opening. The antenna is disposed at a location not overlapping the fixing member in a thickness direction of the fixing member.
