Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample storage devices face challenges in maintaining efficient radio wave transmission and reception between transponders and antennas due to increased distance caused by thicker rails supporting the weight of containers and racks, which can hinder communication.
Innovation Solution
The design incorporates paired rail sections with an antenna array substrate positioned between them, paired slide sections with a support plate transparent to radio waves, and a storage box system that allows for stable and efficient transmission between radio tags and antennas by minimizing the distance between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the rails is increased to bear the weight of the rack and containers, then the structural strength is improved, but the distance between the transponders and antennas increases, causing radio wave transmission failure
Solution Approach 1:
The base is divided into two functional layers: an upper base portion that provides structural support for the rails and rack, and a lower base portion that houses the antennas. This segmentation allows the upper portion to be thick enough for structural strength while keeping the lower portion close to the transponders for radio wave communication.
Solution Approach 2:
The antenna array is positioned in a direction perpendicular to both the separating direction (between paired rail sections) and the extending direction (from opening toward depth), creating a three-dimensional spatial arrangement that optimizes both structural support and radio wave transmission paths.
2Weight of moving object
If the rack and containers are guided through thick rails, then the weight-bearing capacity is improved, but the radio wave transmission between transponders and antennas is hindered
Solution Approach 1:
The base is segmented into an upper base portion for mechanical support and a lower base portion for antenna placement. This allows the rails to be supported by the upper portion while the antennas in the lower portion remain accessible to radio waves from transponders, resolving the conflict between weight-bearing capacity and transmission reliability.
3Reliability
If the distance between transponders and antennas is reduced for efficient radio wave transmission, then the communication efficiency is improved, but the structural support for the rack becomes insufficient
Solution Approach 1:
By segmenting the base into upper and lower portions, the invention allows the upper base portion to provide structural support for the rails and rack, while the lower base portion positions the antennas close to the transponders. This resolves the contradiction between structural support strength and radio wave transmission efficiency.
Solution Approach 2:
The antenna array is arranged in a direction perpendicular to both the separating direction and extending direction, creating optimal three-dimensional positioning that maintains close proximity for radio wave transmission while preserving structural integrity through the layered base design.
