Earring Support Device Transferring Weight to Ear Cartilage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for earrings fail to adequately mitigate the stretching and tearing of the earlobe caused by heavy jewelry, as they redistribute weight to the earlobe rather than leveraging the stronger cartilage structure.
Innovation Solution
A support device with a first portion attachable to the earlobe and a second portion extending to attach to the ear's cartilage, utilizing adhesive layers and materials with varying tensile strengths to transfer the weight from the earlobe to the cartilage, along with an applicator to protect against earring post injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If existing support devices redistribute weight to the earlobe, then some weight support is achieved, but the earlobe stretching and tearing problem worsens
Solution Approach 1:
The patent introduces an intermediary support structure (the device with first and second portions) that mediates between the earring weight and the earlobe. The second portion attaches to the cartilage framework which has higher structural strength, acting as an intermediary load-bearing element that prevents direct weight transmission to the vulnerable earlobe tissue.
Solution Approach 2:
The support device is segmented into two distinct portions: a first portion that contacts the earlobe and a second portion that attaches to the cartilage. This segmentation allows different parts of the device to perform different functions - the first portion provides a comfortable interface with the earlobe while the second portion handles the structural load-bearing function on the stronger cartilage tissue.
2Ease of operation
If the support device uses adhesive layers for attachment, then ease of application is improved, but potential skin irritation or damage may occur
Solution Approach 1:
The adhesive layers are designed with controlled parameters including thickness (0.1-2.0 mm), tensile strength (0.5-5.0 MPa), and elasticity modulus (0.1-1.0 MPa) to balance ease of application with skin safety. These parameter optimizations ensure the adhesive is strong enough for secure attachment but flexible and gentle enough to minimize skin irritation and damage risk.
3Strength
If the first portion has higher tensile strength than the second portion, then attachment security to earlobe is improved, but the device complexity increases
Solution Approach 1:
The device employs local quality differentiation where the first portion (contacting the earlobe) has higher tensile strength (0.5-5.0 MPa) compared to the second portion (0.1-2.0 MPa). This localized strength optimization ensures secure attachment at the critical earlobe interface while maintaining overall device simplicity through a uniform elastic material composition and straightforward geometric design.

Function Achieved in This Case
Effectively reduces the stretching and tearing of the earlobe by distributing the weight of earrings to the stronger cartilage, providing cosmetic improvements, comfort, and protection while preventing further damage.
Implementation Method 1
The support device may comprise an adhesive layer for attaching the first portion to the earlobe and the second portion to the part of the ear comprising cartilage

AI summary
A support device for transferring at least part of the weight of an earring from an earlobe to a part of the ear that comprises cartilage, the device comprising a first portion (P1′) capable of being attached to the earlobe and a second portion (P2′) protruding from the first portion and capable of, when the first portion is attached to the earlobe, extending from the earlobe to attach to the part of the ear comprising cartilage.
