Solution Overview

Problem

Resettable in-line fuses are inconvenient due to the difficulty in identifying when they are tripped and the need to open and inspect them for resetting.

Innovation Solution

A waterproof cover with a translucent seal mount and flexible dome that allows visualization of the reset button when tripped, enabling easy identification and resetting without opening the fuse, while maintaining water resistance through seals on both ends.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a traditional opaque cover is used for the fuse, then the fuse is waterproof and protected, but the reset button cannot be seen when tripped and the fuse cannot be easily identified or reset

Engineering Contradiction:
Improvewaterproof protectionVSAvoididentification and resetting
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The cover transitions from an opaque state to a translucent state through a color change mechanism. When the fuse is tripped, the cover changes from opaque to translucent, allowing the reset button to be visible through the cover. This enables visual identification of the tripped state and easy location of the reset button without opening the cover, while maintaining waterproof protection.

Inventive Principle:
Principle #32Color changes

2Ease of operation

If the cover is made translucent to see the reset button, then the fuse can be identified when tripped, but water resistance may be compromised

Engineering Contradiction:
Improveidentification of tripped stateVSAvoidwater resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cover has different optical properties in different states. When the fuse is normal, the cover is opaque for water resistance. When the fuse is tripped, the cover becomes translucent locally at the reset button area to allow visibility. This local quality change enables identification while maintaining overall water resistance through the seal mechanism.

Inventive Principle:
Principle #3Local quality

3Device complexity

If the cover remains opaque to maintain simplicity and water resistance, then manufacturing is easier, but multiple fuses cannot be quickly inspected to identify the tripped one

Engineering Contradiction:
Improvecover structureVSAvoidinspection speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The cover automatically changes its optical property (from opaque to translucent) when the fuse is tripped, without requiring any manual intervention. This self-service mechanism allows rapid identification of tripped fuses by simply looking through the covers, greatly improving inspection speed while maintaining the simplicity of the overall structure.

Inventive Principle:
Principle #25Self-service

AI summary

A waterproof cover for a resettable in-line fuse having a cover with a top end and a bottom end; a seal mount on the top end; and a flexible seal for the seal mount. The seal mount has a hollow interior and an annular flange. The flexible seal has a top portion, a middle portion, and bottom portion. A translucent flexible dome is positioned on the top portion and an internal annular groove is positioned in the middle portion to engage the annular flange. A seal is positioned in the bottom end of the cover and positioned around a female section of the resettable in-line fuse. A seal is also positioned in a bottom end of the female section of the resettable in-line fuse to produce a waterproof fuse. A reset button is visible in the translucent flexible dome when the resettable in-line fuse is tripped. The fuse can be reset by pushing the flexible dome against the reset button.
