Solution Overview

Problem

Shirt cuffs with buttoned cuffs cannot easily accommodate cuff links, limiting the variety of cuff link configurations that can be used.

Innovation Solution

A cuff link accessory with a base member having opposed ends, featuring a first hole section for engaging the cuff link post and a second hole section for the shirt cuff button, allowing the cuff link to be securely attached to a buttoned cuff shirt by folding the cuff back and using a toggle mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional button and button hole system is used for shirt cuffs, then the cuff can be securely fastened, but the cuff link configuration options are limited

Engineering Contradiction:
Improvecuff link configuration optionsVSAvoidcuff fastening system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a cuff link accessory as an intermediary component that bridges the conventional button system and the desired cuff link functionality. The accessory includes a base member with a first hole section for the cuff link post and a second hole section for the button, allowing the cuff link to be attached to a buttoned cuff shirt without modifying the original button system. This intermediary device enables versatility in cuff link configurations while maintaining the simplicity of the existing button fastening mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a cuff link accessory is designed with multiple hole sections and toggle mechanisms, then the cuff link can be securely attached to buttoned cuffs, but the manufacturing cost and complexity increase

Engineering Contradiction:
Improvecuff link attachment securityVSAvoidmanufacturing cost and complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The cuff link accessory is divided into distinct functional segments: a base member with a first hole section for the cuff link post, a second hole section for the button, and a toggle mechanism for securing the cuff link. This segmentation allows each component to be manufactured separately using simple processes and then assembled, reducing overall manufacturing complexity while ensuring reliable attachment through the specialized hole sections and toggle design.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the cuff link accessory uses a pliable material substrate with elongated slit holes, then the accessory can be easily installed and adjusted, but the structural strength and durability may be reduced

Engineering Contradiction:
Improveinstallation and adjustment easeVSAvoidaccessory structural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The base member is constructed from a pliable material substrate that provides flexibility for easy installation and adjustment. The elongated slit holes are formed within this flexible substrate, allowing the accessory to be bent and positioned easily on the cuff. While the substrate is flexible, the overall structure maintains sufficient strength through the strategic placement of the hole sections and the toggle mechanism, which provides additional structural support where needed.

Inventive Principle:
Principle #30Flexible shells and thin films
