Solution Overview

Problem

Current cable coil packaging requires users to open the cover to check the state of unwinding, which is time-consuming and difficult, especially when the cable is being unwound, leading to inefficiencies in use.

Innovation Solution

A transport device with a viewing window in the envelope allows users to visualize the cable coil without opening the packaging, featuring a reusable, flexible material cover with a resealable opening and a transparent viewing window that can be strategically positioned for quick assessment of the cable's unwinding state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the packaging cover is opened to check the cable coil state, then the user can see the unwinding status, but time is lost and operation becomes difficult

Engineering Contradiction:
Improvecable unwinding state informationVSAvoidtime to open and check packaging
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent applies a transparent or translucent material for the packaging cover, allowing visual detection of the cable coil's unwinding state without opening the packaging. This optical property change enables users to monitor the cable status through the cover, eliminating the need to open and close the packaging repeatedly, thus saving time and improving operational efficiency.

Inventive Principle:
Principle #32Color changes

2Loss of information

If the packaging cover is opened to check the cable coil, then the unwinding status can be seen, but the operation becomes difficult when cable is being unwound

Engineering Contradiction:
Improvecable unwinding state informationVSAvoidease of opening packaging during unwinding
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

By using a transparent or translucent packaging cover, the invention allows users to visually monitor the cable unwinding status through the cover itself. This eliminates the need to physically open the packaging during the unwinding process, making the operation easier and safer when the cable is in motion.

Inventive Principle:
Principle #32Color changes

3Loss of information

If a transparent viewing window is formed in the envelope, then the cable ring can be visualized, but the envelope material must be transparent which may reduce durability

Engineering Contradiction:
Improvecable coil visibilityVSAvoidenvelope material strength
Core Design Contradiction:
Loss of informationVSStrength

Solution Approach 1:

The patent applies transparent or translucent material specifically to the cover or viewing window portion of the packaging, while the rest of the envelope can use more durable, opaque materials. This local application of transparency allows cable visibility where needed while maintaining overall packaging strength and durability through the use of robust materials in non-transparent sections.

Inventive Principle:
Principle #3Local quality
