Earphone Storage Device With Helical Groove Bobbin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Earphone cords tend to tangle and become damaged due to their long length, leading to inconvenience and potential wear and tear.
Innovation Solution
A cylindrical earphone storage device featuring a bobbin with a helical groove and protrusion, along with a latching assembly, that securely winds and stores earphone cords, preventing tangling and damage, while allowing easy access and adjustment for different cord lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If earphone cords are made long to provide sufficient length for use, then usability is improved, but tangling and damage occur more frequently
Solution Approach 1:
The patent extracts the cord management function from the earphone cord itself by introducing a separate storage device (bobbin) that the cord can be wound around. This separates the cord's primary function (audio transmission) from its storage function, allowing the cord to be neatly coiled and secured, preventing tangling and damage while maintaining sufficient length for usability.
2Reliability
If a storage device is designed to securely hold earphone cords, then cord integrity is improved, but the device structure becomes more complex
Solution Approach 1:
The storage device is segmented into distinct functional components: a bobbin for winding the cord, a locking mechanism for securing it, and a housing for protection. This segmentation allows each component to perform its specific function efficiently while keeping the overall design relatively simple and manageable.
Solution Approach 2:
The patent employs a nested structure where the earphone cord is wound around the bobbin, the bobbin is placed inside the housing, and the locking mechanism integrates with the housing structure. This nesting approach maximizes space utilization and secures the cord while avoiding unnecessary structural complexity.
3Reliability
If a storage device is designed with secure locking mechanisms, then cord security is improved, but ease of access is reduced
Solution Approach 1:
The locking mechanism is designed to be dynamic rather than fixed, allowing it to transition between locked and unlocked states. This enables the cord to be securely held during storage while allowing quick and easy access when needed, balancing security with convenience.

AI summary
An earphone storage device includes a storage body having a bobbin, a track, and two sliders. The bobbin has a peripheral surface, an upper surface, a lower surface, a helical groove, and a protrusion. The helical groove is formed on the peripheral surface. The protrusion extends from the lower surface. The protrusion has a side surface and a hole formed in the side surface. The track is secured to the upper surface of the bobbin. The sliders are disposed on the track. The storage body stores earphones with an audio plug, earphone cords, and a pair of earbuds. The audio plug is inserted into the hole of the protrusion of the bobbin, the earphone cords are wound in the helical groove of the bobbin, and the earbuds are held by the sliders. The earphones can be securely stored, and the earphone cords do not tangle.
