Solution Overview

Problem

The existing method of attaching an SD memory card packaging bag to an instruction manual packaging bag using tape can damage the instruction manual packaging bag when updating map data, as it requires peeling off the tape to access the SD memory card.

Innovation Solution

A packaging bag structure with exposed zipper profiles, allowing two bags to be joined and easily detached without damaging the packaging, by engaging male and female zipper profiles when closed, eliminating the need for adhesive tape.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tape is used to attach the SD packaging bag to the instruction manual packaging bag, then the SD packaging bag is securely attached and prevents loss, but the packaging bag is damaged when peeling off the tape to update map data

Engineering Contradiction:

Improveattachment securityVSAvoidpackaging bag integrity

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The packaging bag is divided into separate functional components: the main bag body and a detachable zipper profile component. This segmentation allows the zipper profile to be removed and reattached without damaging the main bag body, resolving the contradiction between secure attachment and packaging integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The zipper profile is designed to be dynamically detachable and reattachable through zipper engagement mechanisms. This dynamic design enables easy removal for map data updates while maintaining secure attachment during normal use, eliminating the need for damaging tape removal.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If tape is used to attach the bags, then the bags remain connected during shipping, but the appearance of the packaging bag degrades when tape is removed

Engineering Contradiction:

Improvebag connection stabilityVSAvoidpackaging bag appearance

Core Design Contradiction:

Stability of the object's compositionVSShape

Solution Approach 1:

The attachment function is extracted from the main bag body and placed into a separate zipper profile component. This extraction allows the connection to be made and removed without affecting the appearance of the main bag, as the zipper profile can be detached cleanly without leaving residue or damaging the bag's exterior.

Inventive Principle:

Principle #2Taking out (Extraction)

3Volume of moving object

If the SD packaging bag is made smaller to fit the SD memory card, then the packaging is optimized for the small item, but the bag is more prone to getting lost in the packaging box

Engineering Contradiction:

Improvepackaging bag sizeVSAvoidbag retention

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The small SD packaging bag is merged with the larger instruction manual packaging bag through the zipper profile attachment system. This combining allows the small bag to be securely retained on the larger bag during shipping, preventing loss while maintaining the optimized small size for the SD memory card.

Inventive Principle:

Principle #5Merging (Combining)
