Solution Overview

Problem

Existing optical joint closures do not provide a means for mounting the assembled enclosure to a wall during the service life, leading to inefficient use of space and installation challenges, especially in manholes and footway boxes.

Innovation Solution

The optical joint closure incorporates a bracket that is integrated within the closure cap, featuring protruding portions for mounting to a wall, allowing the enclosure to be securely attached without external brackets, thus saving space and simplifying installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external mounting brackets and tethers are used to attach the optical joint closure to a wall, then the closure can be securely mounted during service life, but the overall space required increases and installation complexity increases

Engineering Contradiction:
Improvemounting securityVSAvoidoverall space required
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The mounting bracket is merged with the closure cap as an integrated component. The bracket extends through the closure cap with protruding portions that mount to the wall, eliminating the need for separate external mounting brackets and tethers. This integration maintains secure mounting while reducing the overall space required by up to 20%.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If external mounting brackets are used to attach the optical joint closure to a wall, then the closure can be securely mounted, but the device complexity increases due to additional external components

Engineering Contradiction:
Improvemounting securityVSAvoidnumber of external components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The mounting bracket is integrated into the closure cap structure, combining what were previously separate components (closure cap, external bracket, and tether) into a single unified assembly. This reduces device complexity by eliminating multiple external components while maintaining secure mounting capability through the bracket's protruding portions.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If external mounting brackets and tethers are used, then the closure can be attached to a wall, but installation time increases due to additional assembly steps

Engineering Contradiction:
Improvemounting securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The mounting bracket is pre-integrated into the closure cap during manufacturing, with protruding portions already positioned for wall mounting. This preliminary integration eliminates the need for installers to assemble separate brackets and tethers on-site, significantly reducing installation time while maintaining secure mounting.

Inventive Principle:
Principle #10Preliminary action

4Volume of stationary object

If the bracket is contained within the contour of the closure cap, then space is saved, but the bracket must be integrated through the closure cap structure

Engineering Contradiction:
Improveoverall space requiredVSAvoidintegration complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The bracket is designed to extend through the closure cap in a dimensional configuration where the main body of the bracket is contained within the closure cap's contour, while protruding portions extend outward for mounting. This spatial arrangement saves space while managing integration complexity through careful structural design.

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