Interchangeable Earpiece Cable Reel for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable sound and communication devices often require multiple components, including headsets, earpieces, and cables, which can cause damage and inconvenience due to entanglement and the need for separate cable reel assemblies for each device, and may pose health risks from prolonged use.
Innovation Solution
A combined integral extendable and retractable earpiece cable reel platform assembly that is removably attached to a mobile device's casing, allowing for interchangeable use across various devices, with a rewind mechanism and a jack plug holding area to prevent damage and reduce the number of carried items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate headset and cable components are used, then the device can function properly, but the cables and earpieces can become entangled and damaged
Solution Approach 1:
The patent combines the cable reel assembly with the protective casing to create an integrated unit. The reel housing is permanently attached to the casing platform, merging functions of cable storage, device protection, and port management into a single assembly that prevents tangling and damage.
Solution Approach 2:
The cable reel is nested within the protective casing assembly. The earpiece cables are wound around the reel which is housed inside the protective casing, creating a nested structure that keeps cables organized and protected while maintaining access to functionality.
2Adaptability or versatility
If multiple separate components are required (carrying case, headset, device), then each component can be optimized, but the user must carry and manage multiple items
Solution Approach 1:
The patent merges the carrying case function with the device protection casing and cable reel assembly into a single integrated unit. This eliminates the need for separate carrying cases and headsets, reducing the number of components from three to one while maintaining all necessary functions.
Solution Approach 2:
The protective casing assembly serves multiple functions simultaneously: it protects the mobile device, houses the cable reel mechanism, provides a platform for the reel attachment, and acts as a carrying case. This multi-functional design eliminates the need for separate dedicated components.
3Ease of operation
If a dedicated cable reel assembly is provided for each device, then cable management is improved, but the cost and complexity increase for users with multiple devices
Solution Approach 1:
The platform assembly is designed with universal compatibility to attach to various mobile electronic devices. The standardized platform allows the same cable reel assembly to be used across multiple devices, eliminating the need for device-specific reel assemblies while maintaining effective cable management.
