RFID Basket Reader Housing for Wave Containment and Easy Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless tag reading apparatuses face challenges in improving operability while maintaining reading performance, as customers need to hold baskets up to accommodate them, leading to potential radio wave leakage and decreased performance.
Innovation Solution
The apparatus features an accommodation part with a bottom surface and vertically provided peripheral surfaces, including a peripheral surface opening for easy basket entry and exit, and a cover part that covers part of the top surface, forming a contiguous top surface opening to prevent radio wave leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the front surface of the accommodation part is opened to improve operability, then customers can easily slide baskets in without lifting, but radiowaves leak to the outside causing reading performance to decline
Solution Approach 1:
A cover part is introduced as an intermediary component that selectively covers the top surface opening of the accommodation part. The cover part includes a through hole that allows radiowaves to pass through while preventing leakage from the front surface opening, thus mediating between the need for operability and reading performance
Solution Approach 2:
The cover part is positioned specifically at the top surface opening rather than covering the entire accommodation part. This localized covering approach allows the front surface to remain open for easy basket insertion while the cover prevents radiowave leakage from the top, maintaining reading performance only where needed
2Ease of operation
If the top surface of the accommodation part is fully opened to improve basket insertion ease, then customers can easily place baskets, but radiowaves leak causing reading performance to decline
Solution Approach 1:
The cover part selectively covers only the top surface opening of the accommodation part, leaving the front surface opening uncovered. This localized approach allows radiowaves to be contained in the regions that matter for reading performance while still permitting easy basket insertion through the front opening
3Reliability
If the accommodation part is completely enclosed to prevent radiowave leakage, then reading performance is maintained, but operability deteriorates as customers must lift baskets to insert them
Solution Approach 1:
The cover part is applied selectively to the top surface opening rather than enclosing the entire accommodation part. This creates a differentiated structure where the top opening is covered to prevent radiowave leakage and maintain reading performance, while the front surface remains open for easy basket insertion without lifting
Solution Approach 2:
The opening configuration is segmented into two distinct openings: a top surface opening that is covered to prevent radiowave leakage, and a front surface opening that remains uncovered for easy basket insertion. This segmentation allows simultaneous achievement of reading performance and operability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances operability by allowing customers to easily slide baskets into the apparatus without lifting them, while maintaining reading performance by preventing radio wave leakage and ensuring intense radio field intensity inside the accommodation part.
Implementation Method 1
The wireless tag reading apparatus reads tag information using a radio frequency identification (RFID) technology
Implementation Method 2
radiowaves are prevented from leaking to the outside, and the wireless tag reading apparatus maintains reading performance by ensuring radio field intensity inside the accommodation part
