Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor power supply boxes suffer from poor waterproofing due to gaps between the box and cable connections, leading to debris accumulation and operational issues.
Innovation Solution
An outdoor power supply box design featuring a housing with a rotatable cover, arc-shaped slotted compartments, and detachable waterproof components, including casings and sleeves made of flexible materials, which enhance sealing and drainage through guiding and connecting grooves and sealing walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable connection structures are used in outdoor power supply boxes, then the installation is simple, but the waterproofing performance is poor and debris can enter through gaps
Solution Approach 1:
The cable connection structure is divided into multiple segments: arc-shaped slotted compartments for cable accommodation, detachable waterproof components with first and second casings, and waterproof plugs. This segmentation allows each component to perform its specific function while collectively achieving excellent waterproofing without excessive overall complexity.
Solution Approach 2:
The waterproof component employs a nested structure where the first casing and second casing are assembled together, with waterproof plugs nested within the cable access openings. The arc-shaped slotted compartments are nested within the housing, creating multiple layers of protection that enhance waterproofing while maintaining a compact design.
2Object-affected harmful factors
If the power supply box has a fully enclosed housing, then protection against debris is improved, but cable access and ventilation are restricted
Solution Approach 1:
The housing provides full enclosure for overall protection, but the cable access openings are equipped with detachable waterproof components that can be opened or closed as needed. The arc-shaped slotted compartments provide localized cable management while the waterproof plugs can be removed for cable installation and replaced for sealing, allowing flexible operation without compromising overall protection.
Solution Approach 2:
The cable access system is designed to be dynamic rather than static. The detachable waterproof components and removable waterproof plugs allow the structure to transition between sealed and open states, enabling easy cable access when needed while maintaining full enclosure and debris protection during normal operation.
3Ease of operation
If cable access openings are provided in the housing, then cable installation is facilitated, but waterproofing performance deteriorates
Solution Approach 1:
The cable access openings are pre-equipped with detachable waterproof components and waterproof plugs that are designed to be installed before final cable placement. The arc-shaped slotted compartments are pre-formed with guiding grooves that align cables during installation, allowing seamless cable installation while maintaining sealing performance through the pre-installed waterproof components.
Solution Approach 2:
The waterproof plugs and detachable waterproof components act as intermediaries between the cable access openings and the enclosed housing. These intermediary elements provide a transition that allows cable passage while maintaining the sealing barrier, enabling both cable installation and waterproofing performance to coexist.
4Adaptability or versatility
If multiple cable access openings are provided, then adaptability to different cable configurations is improved, but the risk of water and debris infiltration increases
Solution Approach 1:
The arc-shaped slotted compartments with detachable waterproof components provide a universal cable access solution that can accommodate different cable configurations, sizes, and quantities. The same basic structure with adjustable waterproof plugs can adapt to various cable arrangements while maintaining consistent waterproofing and debris protection across all access points.
Solution Approach 2:
Each cable access opening is equipped with its own detachable waterproof component and waterproof plug, providing localized sealing at each penetration point. This ensures that water and debris infiltration risk is minimized at each individual opening while the overall system maintains adaptability to different cable configurations through the modular nature of these localized sealing solutions.

AI summary
An outdoor power box includes a housing and a detachable waterproof component on the front side of the housing for cable connection. The housing includes a base box and a rotatable cover that fully encloses it. Both have arc-shaped slots, forming a cavity for wire accommodation. The walls of the slots are provided with at least one groove. The waterproof component includes a rigid first casing, a second casing, a first waterproof sleeve, and a second waterproof sleeve. The first casing and the second casing are equipped with clasps that cooperate with the grooves, and the first casing is installed on the cover by clasping, while the second casing is installed on the base box by clasping. The power box only has slots and channels, ensuring a good overall sealing effect. Waterproof components and plugs greatly enhance the waterproof performance and ensure reliable sealing when used outdoors.
