Handheld Material Quality Tester with Maximum-Compression Indicator

Solution Overview

Problem

Existing methods for testing the quality of packaging materials, such as corrugated board, are not well-suited for use in field settings, leading to uncertain quality control and potential damage to products during shipping and handling.

Innovation Solution

A quality-control device comprising a housing, a biasing member, a reciprocating puncturing member, and a maximum-compression indicator that allows for easy, inexpensive, and universal testing of material strength by correlating the furthest point of puncture with a gauge, providing a simple or quantitative measure of material quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If known testing methods are used to assess material strength, then measurement capability is provided, but the methods are not suitable for field use and require complex equipment

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the essential testing function from complex laboratory equipment and implements it in a simplified handheld device. The puncturing member and spring mechanism isolate only the necessary components for strength testing, eliminating unnecessary complexity while maintaining field usability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The device uses inexpensive, replaceable components such as the puncturing member and spring mechanism that can be easily replaced or recalibrated. This allows the device to remain simple and portable while maintaining testing accuracy through component replacement rather than complex recalibration systems.

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

2Reliability

If quality control is strengthened to ensure material specifications, then product protection is improved, but testing cost and time increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The device enables preliminary quality checks to be performed at the point of use rather than requiring materials to be sent to laboratories for testing. The spring mechanism and puncturing member provide immediate strength assessment, allowing quality control to be integrated into the normal workflow without significant time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The device is designed for self-testing by end users without requiring specialized training or laboratory infrastructure. The gauge provides automatic reading interpretation, and the device requires minimal calibration, allowing users to perform quality control themselves without external support.

Inventive Principle:
Principle #25Self-service

3Strength

If material strength is increased to ensure adequate protection, then product safety is improved, but material cost increases

Engineering Contradiction:
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The gauge provides immediate feedback on material strength through the position of the maximum-compression indicator. This allows users to verify that materials meet minimum strength requirements without over-specifying, enabling cost-effective material selection based on actual performance data rather than conservative over-engineering.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The device enables users to test and compare different material parameters (strength, compression resistance) to select the minimum adequate specification rather than using over-engineered materials. The spring mechanism and gauge provide quantitative data to optimize material selection for cost-effectiveness.

Inventive Principle:
Principle #35Parameter changes

AI summary

A quality-control device comprises a housing, a biasing member disposed within the housing, and a reciprocating puncturing member that is configured and oriented to selectively move inwardly of the housing in opposition to the biasing member. A maximum-compression indicator is configured to move inwardly of the housing in tandem with the puncturing member and a gauge serves to correlate a particular location of the maximum-compression indicator to a corresponding measure of compression as corresponds to a material being tested for quality. By one approach the indicator moves in response to inward movement of the puncturing member but is also configured to not move when the puncturing member moves outwardly of the housing. So configured the maximum-compression indicator will remain located at a point that corresponds to the furthest inward incursion of the puncturing member in opposition to the biasing member when the user presses the puncturing member against the material.
