Innovation Solution

A kit comprising a hat attachment assembly with magnetically connectable temple attachment members, allowing for secure and universal attachment of sunglasses to any type of hat without the need for extensive modification or complex installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If magnets are affixed to temples and a specialized hatband insert is used, then glasses can be securely retained, but the device complexity increases and requires multiple component pieces

Engineering Contradiction:

Improveglasses retention securityVSAvoidnumber of component pieces

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the magnet and the hatband insert into a single integrated component. The magnet is embedded within the hatband insert structure, eliminating the need for separate magnetic components and reducing the overall number of parts while maintaining secure glasses retention through magnetic attraction to the temple

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hatband insert is designed to be universally applicable to various hat types and works with standard glasses temples. The integrated magnet design allows the same component to function both as a structural element of the hatband and as a magnetic retention mechanism, reducing the need for specialized components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a retractable tether mechanism is used to attach glasses to hat, then glasses can be retained, but the solution requires specialized glasses with adjustable lenses and creates an unsightly tether appearance

Engineering Contradiction:

Improveglasses retention securityVSAvoidaesthetic appearance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the magnetic retention function from the temple area and relocates it to the hatband insert. This eliminates the need for visible tethers or adjustment mechanisms on the glasses themselves, allowing standard glasses to be used without specialized components while maintaining secure retention

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The hatband insert acts as an intermediary component that provides the magnetic retention function. Instead of modifying the glasses with tethers or adjustment mechanisms, the magnetic field is transmitted through the hatband insert to hold the glasses in place, eliminating visible tethers while maintaining security

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If magnets are attached to the sides of the hat with a cavity design, then glasses can be securely held, but the manufacturing cost increases and the magnetic cavity on the outside of the hat is undesirable

Engineering Contradiction:

Improveglasses retention securityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The magnet is integrated within the hatband insert structure rather than requiring separate cavity formations in the hat. This merging of the magnetic component with the existing hatband structure simplifies manufacturing by eliminating the need for additional cavity work while maintaining secure glasses retention

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hatband insert with embedded magnet is designed as a separate, replaceable component that can be easily attached and removed. This modular approach allows for simpler manufacturing compared to permanent cavity modifications, and the component can be replaced if needed without affecting the hat itself

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

AI summary

A kit for securing eyeglasses to headwear includes a hat attachment assembly having an engaging plate, a retaining plate, and a first magnetic material. The retaining plate defines a throughhole, and a prong extending from the engaging plate engages the retaining plate by insertion through the headwear and throughhole. A temple attachment member has a flexible hollow sleeve, a recessed surface on one side of the sleeve, and second magnetic material installed in the recessed surface. The flexible hollow sleeve can slidably engage a temple of the eyeglasses, so that the eyeglasses when placed on the headwear equipped with the attachment assembly are held thereto by attraction of the magnetic materials. The first and second magnetic materials may be interchangeably installed in the engaging plate and the flexible sleeve.
