Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Utility junction boxes on exterior structures are prone to corrosion, weather damage, and difficulty in access for repairs, leading to leaks and costly repairs due to lack of resistance against extreme weather conditions like hurricanes and high winds.

Innovation Solution

A utility junction box design featuring weather-resistant materials, sloping weather guards, and a secure lid mechanism with gas assist struts and locking systems to protect utility lines from weather and facilitate easy access for maintenance, including apertures for directing utility lines and using weatherproofing materials for sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional utility junction boxes are used on exterior structures, then they provide basic protection for utility lines, but they are prone to corrosion and weather damage leading to degradation over time

Engineering Contradiction:

Improveresistance to corrosion and weather damageVSAvoidservice life of utility junction box

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The utility junction box is constructed from corrosion-resistant materials such as stainless steel, aluminum, or other suitable materials that provide enhanced protection against weather degradation and corrosion, extending the service life of the junction box in exterior applications

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The junction box design incorporates modified structural parameters including reinforced walls, improved sealing features, and weather-resistant coatings that change the physical properties of the box to resist environmental degradation and extend durability

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If utility junction boxes are installed on exterior structures, then they protect utility lines from weather, but they can begin to leak causing utility line connections and components to be damaged

Engineering Contradiction:

Improveprotection from rain and windVSAvoidsealing integrity against leaks

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The junction box incorporates flexible gaskets, seals, and membrane structures that create weather-tight barriers while accommodating thermal expansion and contraction, preventing leaks during extreme weather conditions such as hurricanes and high winds

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The design includes removable and replaceable seal components that can be inspected, maintained, or replaced independently of the main junction box structure, ensuring continuous sealing integrity and preventing water infiltration

Inventive Principle:

Principle #34Discarding and recovering

3Reliability

If utility junction boxes are installed on exterior structures, then they house utility lines and connections, but they are not easy to access within for repairs

Engineering Contradiction:

Improveprotection of utility connectionsVSAvoidaccessibility for maintenance and repairs

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The junction box is designed with modular components including removable panels, hinged lids, and segmented walls that can be easily opened and accessed for maintenance, allowing technicians to reach utility connections without dismantling the entire structure while maintaining protection when closed

Inventive Principle:

Principle #1Segmentation

4Object-affected harmful factors

If utility junction boxes are used in extreme weather climates, then they provide basic weather protection, but they are not designed for hurricanes, hail, high winds and potential for high velocity missile impact damage

Engineering Contradiction:

Improveresistance to extreme weather conditionsVSAvoidresistance to hurricane and missile impact

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The junction box incorporates curved and rounded structural elements that better distribute impact forces from hail and missile strikes, reducing stress concentration points and enhancing resistance to extreme weather conditions including hurricanes

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The junction box is pre-engineered with reinforced structural features, impact-resistant materials, and hurricane-rated construction standards before installation, providing proactive protection against extreme weather events rather than relying on post-event repairs

Inventive Principle:

Principle #10Preliminary action

AI summary

There is provided a utility junction box including a plurality of sidewalls forming a housing having an open bottom opening into an interior volume for receiving one or more utility lines from a first location, one or more apertures formed in at least one sidewall of the housing, a weather guard disposed on an exterior of the at least one sidewall having a downwardly sloping front face having formed therein one aperture corresponding to each of the one or more apertures formed in the at least one sidewall of the housing and disposed directly opposite therefrom. Each aperture formed in the sidewall of the housing is configured to allow a utility line to pass from within the interior volume of the housing through the aperture and direct the utility line through the corresponding aperture formed in the weather guard to a second location exterior to the utility junction box.
