Solution Overview

Problem

Existing adjustable wrench packaging interferes with the ability to test adjustment experience and is difficult to remove after purchase, necessitating a balance between security and interactivity in display means.

Innovation Solution

A hang tag design with a base member, folding member, and locking assembly that securely holds the wrench for display while allowing access to the worm gear, enabling two-finger operation without removing the tag.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional packaging is used to secure the wrench for display, then security and protection are improved, but customer ability to test operation and ease of removal deteriorate

Engineering Contradiction:
ImprovesecurityVSAvoidability to test operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The packaging system is divided into separate functional components: a display tag portion and a removable packaging portion. The display tag remains attached to the wrench handle after purchase, while the packaging can be easily removed. This segmentation allows the wrench to be securely displayed yet easily tested and removed after purchase.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The worm gear access function is extracted from the packaging structure and integrated directly into the display tag through an opening or window. This allows customers to access and test the worm gear operation directly through the display tag without removing the entire packaging, maintaining security while enabling interaction.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If packaging completely encloses the wrench for security, then protection is improved, but accessibility to test worm gear operation deteriorates

Engineering Contradiction:
ImproveprotectionVSAvoidaccessibility to worm gear
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The display tag incorporates a localized opening or window positioned to provide direct access to the worm gear area. This localized modification allows customers to test worm gear operation through the tag without compromising the overall protective enclosure, maintaining security while enabling specific interactive access.

Inventive Principle:
Principle #3Local quality

3Reliability

If packaging is designed to be secure and difficult to remove, then theft prevention is improved, but customer convenience and ease of removal after purchase deteriorate

Engineering Contradiction:
Improvetheft preventionVSAvoidease of removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The packaging system employs dynamic characteristics with different removal resistances for different components. The display tag is designed to remain permanently attached to the wrench handle, while the packaging portion is designed for easy removal. This dynamic design allows the system to provide security during display while facilitating convenient removal after purchase.

Inventive Principle:
Principle #15Dynamics

AI summary

A hang tag for display of an adjustable wrench having a fixed jaw and a movable jaw may include a base member, and a folding member that folds to engage with the base member to retain the adjustable wrench in the hang tag. The base member may include a hanging portion that includes a hanging aperture through which a hook or other protrusion is insertable to suspend the hang tag, and a retaining portion that also includes the folding member and that retains the adjustable wrench responsive to the folding member contacting the base member to enclose a neck of the adjustable wrench via a locking assembly. An operating window may be formed at the retaining portion of the base member to enable access to a worm gear on opposite sides of the adjustable wrench.
