Solution Overview

Problem

Existing drinks crates with UHF transponder devices face challenges in error-free bulk detection due to interference from residues and impurities, leading to inaccurate data reading during the handling of empties.

Innovation Solution

The UHF transponder device is integrated into a drinks crate with a base and side walls, positioned at least 60% of the side wall's height from the bottom, within a cavity in the side wall to minimize interference, and secured using a flexible carrier element and adhesive for protection and secure fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the UHF transponder device is positioned close to the bottom of the drinks crate for compact integration, then device complexity is reduced, but measurement precision deteriorates due to interference from residues and impurities

Engineering Contradiction:
Improveintegration complexityVSAvoiddata reading accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The transponder device is relocated from the bottom surface to the side wall of the crate, changing the spatial dimension of integration. This vertical relocation along the side wall allows the antenna to be positioned away from interfering substances while maintaining compact overall structure through optimized mounting geometry

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of manufacture

If the transponder arrangement is mounted on the bottom of the crate for simple integration, then ease of manufacture is improved, but reliability deteriorates due to signal interference from residues and impurities

Engineering Contradiction:
Improveintegration easeVSAvoiddata reading reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The side wall cavity acts as an intermediary space that isolates the transponder device from interfering substances. The adhesive and carrier element serve as intermediaries to securely mount the device in this intermediate position, ensuring both reliability through interference reduction and ease of manufacture through standardized mounting procedures

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If multiple transponder devices are read simultaneously during bulk detection for increased productivity, then productivity is improved, but measurement precision deteriorates due to signal interference and reading errors

Engineering Contradiction:
Improvebulk detection speedVSAvoiddata reading accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

Each transponder device is given an optimized local position on the side wall with sufficient spacing from other devices and from interfering substances. This localized optimization of each device's electromagnetic environment ensures reliable individual readings even during simultaneous bulk detection of multiple crates

Inventive Principle:
Principle #3Local quality

AI summary

The beverage crate (2) comprises a bottom portion (10), sidewalls (6.1,6.2), and a transponder array (4) including a radio frequency (RF) or ultra-high frequency (UHF) transponder (16). The transponder array is integrated into a cavity formed in a sidewall such that the RF transponder is spaced apart from the bottom portion by at least 60% of the height the sidewall. The transponder array comprises a flexible support (18) mounted with the transponder. The support is shaped in such a way that it encloses the transponder receiving element of the transponder array. Independent claims are included for the following: (1) a method for integrating transponder array into a beverage crate; and (2) an apparatus for integrating transponder array into a beverage crate.
