Solution Overview

Problem

Conventional packing methods for instrument strings require twisting and inserting the string end between twisted portions to prevent it from springing out, leading to deformation and increased packing complexity, which affects sound quality and storage efficiency.

Innovation Solution

A package with a base plate and fastening units that allow the instrument string to be wound and inserted between the base plate and fasteners, eliminating the need for twisting and minimizing deformation, while enabling multiple strings to be packed in a single bundle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the instrument string is wound in a circle and twisted to prevent the end from springing out, then the packing reliability is improved, but the instrument string undergoes permanent deformation that affects sound quality

Engineering Contradiction:

Improvepacking reliabilityVSAvoidstring straightness

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent introduces a base plate as an intermediary object between the wound instrument string and the packing bag. The base plate provides a flat surface that supports the wound string, preventing the end from springing out without requiring twisting of the string itself. This mediator enables reliable packing while maintaining string straightness and sound quality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the instrument string is twisted and the end is inserted between twisted portions to prevent springing out, then the packing reliability is improved, but the packing process complexity increases

Engineering Contradiction:

Improvepacking reliabilityVSAvoidpacking process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the function of preventing the string end from springing out from the string itself and transfers it to the base plate. Instead of twisting the string and inserting the end between twisted portions, the base plate provides a flat surface that naturally secures the wound string, eliminating complex packing steps while maintaining reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If multiple instrument strings are packed separately in individual packing bags, then each string is protected, but the storage volume increases

Engineering Contradiction:

Improvestring protectionVSAvoidstorage volume

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent merges multiple wound instrument strings together on a single base plate, allowing them to be packed as one unit rather than in separate packing bags. This combining approach maintains protection of each string while significantly reducing the total storage volume required for multiple strings.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A package for an instrument string includes a base plate, and a fastening unit which includes at least two fasteners provided on the base plate to receive the instrument string where the instrument string that is in a wound state is inserted between the base plate and the at least two fasteners and fastened to the base plate before the instrument string is packed into a packing bag to make a work of packing the instrument easy.
