Solution Overview

Problem

Existing solutions for managing cables with electronic devices, such as mobile phones and chargers, often result in tangled, damaged, or lost cables due to chaotic winding and separate spools, and existing cable tidies are complex and expensive.

Innovation Solution

A unified casing with integral receiving and winding portions, designed for compact storage and defined cable winding, featuring protrusions, lateral extensions, and holding sections to secure cables without separate components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If cables are wound around the electronic device, then the cable is stored during transport, but the cable may get damaged when wound in a too small radius and causes disadvantageous appearance

Engineering Contradiction:
Improvecable storageVSAvoidcable damage
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The casing is divided into two distinct portions: a receiving portion for the electronic device and a winding portion for the cable. This segmentation allows the cable to be wound in a dedicated space with appropriate radius, preventing damage while maintaining compact transport storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The winding portion extends in a direction perpendicular to the receiving portion, creating a three-dimensional structure. This dimensional extension provides sufficient winding radius for the cable without increasing the footprint area, solving the conflict between compact storage and cable protection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If a separate cable spool is used, then the cable can be wound properly, but the spool may get lost when not in use

Engineering Contradiction:
Improvecable damage preventionVSAvoidnumber of separate parts
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cable winding function is merged with the electronic device housing by integrating the winding portion directly into the casing. This eliminates the need for separate cable spools while maintaining proper cable winding capabilities, preventing loss and reducing the number of components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The casing serves multiple functions: it protects the electronic device in the receiving portion and simultaneously provides cable winding and storage in the winding portion. This multi-functionality eliminates the need for separate cable management devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the casing is made in one piece, then the manufacturing is simplified and costs are reduced, but the receiving portion and winding portion must be permanently connected

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidcasing configuration flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The casing is designed as a single integrated piece with distinct receiving and winding portions. This monolithic structure simplifies manufacturing through processes like injection molding while the internal segmentation provides functional flexibility for different cable and device configurations.

Inventive Principle:
Principle #1Segmentation
