Solution Overview

Problem

Current methods for providing conductors on blister package lids are expensive and environmentally hazardous, involving costly chemicals and generating hazardous waste.

Innovation Solution

A continuous pattern of electrically conductive wire is formed on an adhesive surface of a substrate with detector segments, each having destructible portions and connector portions, connected in an arced configuration, allowing for electronic monitoring without the need for expensive chemicals or hazardous processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conductive inks or print-and-etch processes are used to provide conductors on the lid, then the blister package can be electronically monitored, but the manufacturing cost increases and hazardous waste is generated

Engineering Contradiction:
Improveelectronic monitoring capabilityVSAvoidhazardous waste
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful chemical processes (printing and etching) from the conductor formation process and replaces them with a mechanical wire placement method. The conductive wire is directly applied to the lid substrate using adhesive, eliminating the need for chemical inks, printing processes, and etching chemicals that generate hazardous waste.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the chemical-based print-and-etch process with a mechanical wire placement system. Conductive wire is mechanically positioned and adhered to the lid substrate, substituting chemical reactions with physical bonding mechanisms that do not generate hazardous waste.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If conductive inks or print-and-etch processes are used to provide conductors on the lid, then the blister package can be electronically monitored, but the manufacturing cost increases

Engineering Contradiction:
Improveelectronic monitoring capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent uses inexpensive conductive wire and adhesive materials instead of costly conductive inks and etching chemicals. The wire placement method employs low-cost materials that can be easily applied and removed if necessary, reducing overall manufacturing costs while maintaining electronic monitoring functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent removes the expensive chemical processing steps (printing and etching) from the manufacturing process and replaces them with a simpler, lower-cost wire placement method using adhesive bonding, thereby reducing material and processing costs.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-generated harmful factors

If a continuous pattern of wire with detector segments is formed on the adhesive surface, then environmental impact is reduced, but the wiring structure becomes more complex

Engineering Contradiction:
Improveenvironmental impactVSAvoidwiring structure
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The patent divides the continuous wire pattern into multiple detector segments, each capable of independent function. This segmentation allows the wiring to detect events at multiple locations (e.g., pill removal from different cavities) while using a simple wire-and-adhesive construction that avoids complex chemical processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines multiple detector segments into a single continuous wire pattern on the lid. This merging approach simplifies the overall structure by using one continuous wire rather than multiple separate wires, reducing the number of components and assembly steps while maintaining multiple detection points.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Approaches for use in making a lid for a blister package include forming a continuous pattern of electrically conductive wire on an adhesive surface of a substrate. The continuous pattern has a plurality of detector segments, and each detector segment has an outer connector portion and an inner connector portion. The outer connector portion and the inner connector portion of each detector segment are adjacent to one another, and pairs of successive first and second detector segments of the plurality of detector segments are connected by the inner connector portion of the first detector segment and the outer connector portion of the second detector segment. The forming includes forming an arced segment between the inner connector portion of the first detector segment and the outer connector portion of the second detector segment.
