Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof and breathable plugs for electrical boxes are prone to insect damage, have fixed air openings that cannot regulate airflow effectively, and are susceptible to deformation in adverse weather conditions, limiting their waterproof and ventilation capabilities.
Innovation Solution
A waterproof and breathable plug with a protection net assembled in arched blocks to prevent insect damage, featuring adjustable free openings and a collet to secure the membrane, ensuring increased airflow and preventing deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof and breathable membrane is used in the plug, then waterproofing capability is improved, but the membrane is easily damaged by insects
Solution Approach 1:
A protection net is introduced as an intermediary element between the insects and the waterproof and breathable membrane. The net acts as a barrier that allows air and water vapor to pass through while physically blocking insects from contacting and damaging the membrane, thus resolving the contradiction between maintaining waterproofing capability and preventing insect damage
2Reliability
If the plug has a constant-sized opening for waterproofing, then waterproofing is maintained, but air ventilation amount is limited
Solution Approach 1:
The plug design incorporates adjustable openings that can dynamically change size according to ventilation requirements. The protection net structure allows the opening size to be modified while maintaining waterproofing capability, enabling the system to adapt between prioritizing waterproofing or air ventilation based on environmental conditions
3Productivity
If the membrane is made breathable for ventilation, then air flow is improved, but the membrane is likely to deform in bad weather
Solution Approach 1:
The protection net is designed as a flexible structure that can accommodate membrane expansion and contraction during weather changes. The net's flexibility allows it to maintain its protective function while preventing excessive membrane deformation, thus preserving both breathability and structural stability under varying environmental conditions

AI summary
A waterproof and breathable plug is provided. A protection net is assembled with one side or two sides of a waterproof and breathable membrane, to prevent insects from contacting and damaging the waterproof and breathable membrane. A collet is further assembled with the waterproof and breathable membrane, to prevent the waterproof and breathable membrane from moving, contracting and being deformed. The collet is also easily to be assembled in a breathable bolt. The waterproof and breathable plug is adjustable to regulate the breathing rate, fitting different electrical boxes or different weather conditions. Therefore, the problems of the prior art that the conventional waterproof and breathable membrane is easily bit by insects, the waterproof and breathable membrane has a constant-sized opening that cannot regulate the air amount, and the waterproof and breathable membrane is likely deformed due to the bad weather and high humidity and temperature are thus overcome.
