Solution Overview

Problem

The existing methods for controlling multiple helical antennas in electronic cigarette cartridges are time-consuming and complex, leading to reduced productivity due to the need to evaluate the correct functioning of each antenna while distinguishing its response from nearby antennas.

Innovation Solution

A method and machine are developed to efficiently control a group of articles, specifically electronic cigarette cartridges with multiple coils, by using a winding machine that winds and welds coils in various orientations, allowing for simultaneous control of all coils in a single unit of time, thereby optimizing the control process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If controls are carried out to verify the correct operation of each antenna by discriminating the response of each single antenna from the response of other nearby antennas, then measurement precision is improved, but productivity deteriorates

Engineering Contradiction:
Improvecontrol precisionVSAvoidoperating speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent applies segmentation by dividing the control process into two distinct phases: a first control phase that evaluates all antennas collectively using a group evaluation function, and a second control phase that evaluates individual antennas using a differential evaluation function. This segmentation allows the system to maintain measurement precision for individual antennas while improving overall productivity by avoiding the need to discriminate individual responses during the initial screening phase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements partial action by applying different levels of control scrutiny to different antennas based on their evaluation results. Antennas that pass the first control phase with the group evaluation function proceed to the second phase with individual evaluation, while those that fail are rejected without requiring full individual discrimination. This partial application of excessive control measures optimizes the balance between precision and productivity.

Inventive Principle:
Principle #16Partial or excessive action

2Reliability

If controls are carried out to evaluate the correct functioning of each single antenna, then reliability is improved, but loss of time increases

Engineering Contradiction:
Improvecontrol reliabilityVSAvoidcontrol time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control process is segmented into two phases: a first reliable group evaluation that quickly screens multiple antennas, and a second phase that provides individual reliability verification only when necessary. This segmentation reduces the total control time while maintaining reliability by avoiding redundant individual evaluations for all antennas.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first control phase with group evaluation function serves as a preliminary action that pre-screens antennas before individual evaluation. This preliminary filtering reduces the number of antennas that require time-consuming individual discrimination, thereby reducing overall loss of time while maintaining control reliability through the two-stage approach.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If a plurality of helical antennas are used with different orientations in space, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication effectivenessVSAvoidcontrol complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by using a single transponder with multiple helical antennas that can operate in different orientations in space, allowing the same device to maintain effective communication regardless of its spatial position or orientation. This multi-functional antenna system eliminates the need for separate transponders for different orientations, thereby improving adaptability while managing device complexity through a unified design.

Inventive Principle:
Principle #6Universality (Multi-functionality)
