Antenna Holder with Interlinking Mechanism for Variable Body Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna holders for capsule endoscope systems face challenges in securely attaching receiving antennas on subjects with varying body types, such as normal and obese builds, requiring adjustments to ensure optimal positioning and stability of the antennas for effective wireless signal reception.
Innovation Solution
An antenna holder with a detachable antenna attachment portion featuring multiple fixing positions, an interlinking mechanism for variable positioning, and expanding and contracting portions to accommodate different body shapes, allowing for secure and adjustable attachment of receiving antennas without the need for manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If receiving antennas are fixed at predetermined positions on the antenna holder, then the structure is simple and easy to manufacture, but the antenna holder cannot accommodate subjects with varying body types (normal and obese builds)
Solution Approach 1:
The antenna holder employs a flexible interlinking portion that enables dynamic adjustment of the antenna attachment portion's position and shape. This flexible connection allows the holder to adapt to different body types (normal and obese builds) while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
The antenna holder is divided into multiple segments including the antenna attachment portion, interlinking portion, and fitting portion. This segmentation allows each part to perform its specific function independently, enabling adaptability through the interlinking portion while keeping the manufacturing of individual components simple.
2Reliability
If the antenna holder is designed to fit tightly on the subject's body, then the antennas are securely positioned, but it becomes difficult to accommodate different body builds
Solution Approach 1:
The antenna holder utilizes a flexible belt-like structure that can conform to different body shapes while maintaining secure contact. The flexibility allows the holder to adapt to various body builds (normal and obese) while ensuring reliable antenna positioning through tight fitting, thus resolving the contradiction between stability and adaptability.
Solution Approach 2:
The flexible interlinking portion provides dynamic adaptability, allowing the antenna holder to adjust its shape and size to match different body builds while maintaining secure positioning of the antennas through the fitting portion.
3Reliability
If multiple receiving antennas are attached to the antenna holder, then wireless signal reception is improved, but the weight and bulk of the antenna holder increases
Solution Approach 1:
Multiple receiving antennas are integrated into a single antenna holder unit, combining their functions while sharing common structural support. This merging approach improves wireless signal reception through multiple antennas while avoiding the cumulative weight and bulk of separate holders, as all antennas are attached to one unified structure.
