Solution Overview

Problem

Conventional biochemical test strips in moistureproof containers suffer from inefficient moisture absorption, leading to poor moistureproof effects and difficulty in removing the strips, which can result in dampness and affected test results over time.

Innovation Solution

A moistureproof unit with semicircular or hemispherical water absorption units is applied to the container structure, enhancing moisture absorption by increasing the absorption area and reducing the strength required for thermocompression, allowing for easier strip removal and improved moisture management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If moistureproof grains are filled in the cover body, then moisture absorption is provided, but the moisture absorption efficiency is poor and the biochemical test strip is difficult to remove

Engineering Contradiction:

Improvemoistureproof effectVSAvoidease of removing test strip

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The moistureproof grains are segmented into two groups: first moistureproof grains in the cover body and second moistureproof grains in the container body. This segmentation allows moisture to be absorbed from both the upper chamber (above test strip) and lower chamber (below test strip), improving moistureproof efficiency while maintaining ease of test strip removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention transitions from a single-location moisture absorption approach (only in cover body) to a multi-location approach (both cover body and container body). This spatial dimensionality change enables comprehensive moisture absorption from all directions, resolving the contradiction between moistureproof effectiveness and ease of operation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If moistureproof grains are disposed only in the cover body, then the structure is simple, but the moisture absorption area is insufficient leading to poor moistureproof effect

Engineering Contradiction:

Improvestructure complexityVSAvoidmoistureproof effect

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The moistureproof function is segmented across two locations: cover body and container body. This segmentation increases the total moisture absorption area without significantly complicating the overall structure, as each location uses simple grain-filled chambers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the container are assigned moistureproof functions: the cover body handles moisture from the upper chamber while the container body handles moisture from the lower chamber. This local quality assignment optimizes moisture absorption efficiency without requiring complex centralized structures.

Inventive Principle:

Principle #3Local quality

3Reliability

If the thermocompression strength is high, then the sealing is good, but the user must use excessive force to tear off the packaging

Engineering Contradiction:

Improvesealing qualityVSAvoidforce required to remove packaging

Core Design Contradiction:

ReliabilityVSForce

Solution Approach 1:

The thermocompression sealing is applied locally only at the periphery of the packaging sheet rather than across the entire surface. This localized sealing maintains adequate sealing quality for moistureproofing while significantly reducing the force required by users to tear off the packaging.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of applying full-strength thermocompression across the entire packaging surface, the invention uses partial action by sealing only the peripheral region. This partial sealing provides sufficient moistureproof protection while making the packaging easier to open.

Inventive Principle:

Principle #16Partial or excessive action
