Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional earring back-fasteners require precise alignment with a hole, which can be inconvenient and may exert pressure on the earlobe, especially for individuals with stretched or enlarged earlobes, and do not accommodate various earring post sizes and shapes effectively.

Innovation Solution

An ornamental earring backing without a hole, made from a flexible elastomer such as silicone, that can be securely attached to earrings of any shape and size, allowing the post to be inserted from any side and providing superior support without additional pressure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional earring back-fastener with a hole is used, then the earring can be secured to the earlobe, but precise alignment is required which makes operation inconvenient and may exert pressure on the earlobe

Engineering Contradiction:

Improveease of attachmentVSAvoidpressure on earlobe

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention removes the hole from the earring backing, extracting the alignment constraint that caused operational inconvenience and pressure on the earlobe. The post can now be inserted from any direction without requiring precise alignment with a pre-defined hole location.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The earring backing is made from a flexible elastomer material that can deform to accommodate the earring post insertion from any angle. This flexibility allows the backing to conform to different earlobe shapes and sizes without exerting excessive pressure, while still providing secure retention.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If a conventional earring back-fastener with a hole is used, then the earring can be secured, but it does not accommodate various earring post sizes and shapes effectively

Engineering Contradiction:

Improveaccommodation of post sizes and shapesVSAvoidsecure attachment

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The holeless earring backing design provides universal compatibility with earring posts of various sizes, shapes, and materials. The flexible elastomer material and absence of a fixed hole allow the backing to adapt to different post configurations while maintaining reliable attachment through friction and elastic deformation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention changes the physical parameters of the backing by using a flexible elastomer material with appropriate durometer properties. This allows the backing to deform during post insertion and then maintain a secure fit, accommodating variations in post diameter and shape while ensuring reliable attachment for all earring types.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the earring backing is made from a flexible elastomer without a hole, then versatile attachment is achieved, but the structure becomes more complex compared to traditional hole-based designs

Engineering Contradiction:

Improveversatility of attachmentVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges the functions of alignment guidance, post retention, and pressure distribution into a single integrated flexible elastomer component. By eliminating the separate hole feature and using the continuous flexible material to provide all necessary functions, the overall device complexity is actually reduced despite the increased material sophistication.

Inventive Principle:

Principle #5Merging (Combining)
