Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric wire connectors fail to effectively suppress sparks and subsequent fires at the early stage, leading to potential large fires due to weak insulation and contact failures.
Innovation Solution
An electric wire connector with a fire-extinguishing module that automatically ejects fire-extinguishing powder in response to heat, utilizing a metal tube and heat dissipation pins to conduct heat to the fire-extinguishing module, and a dome-shaped compartment that explodes to visually indicate a fire, preventing ember ignition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulation processing by winding insulating tapes is used, then insulation is provided, but the fixing power is weak and the adhesive becomes sticky over time leading to fire hazards
Solution Approach 1:
The patent extracts the adhesive function from the insulation system by using a press-fit metal tube structure that mechanically secures wires without relying on adhesive bonds. The metal tube is crimped onto the wire insulation, providing a permanent mechanical connection that eliminates the sticky adhesive problem while maintaining insulation integrity.
Solution Approach 2:
The patent employs composite construction by combining the metal tube (conductive material) with the wire insulation (non-conductive material) to create a secure mechanical connection. The metal tube provides structural strength and mechanical fixation, while the wire insulation provides electrical isolation, together solving both the durability and insulation requirements.
2Device complexity
If conventional connectors without fire-extinguishing function are used, then结构简单性 is maintained, but sparks cannot be suppressed at early stage leading to large fires
Solution Approach 1:
The patent incorporates fire-extinguishing powder into the connector housing in advance, positioned to be directly accessible to any sparks that may occur at the wire connection point. This preliminary preparation ensures that when a spark occurs, the extinguishing powder is already in position to suppress it immediately, preventing fire development without adding complex active sensing or actuation systems.
Solution Approach 2:
The fire-extinguishing powder acts as an intermediary substance between the spark (harmful factor) and the surrounding environment. When a spark occurs, the powder intercepts and suppresses the combustion process, serving as a mediating element that prevents the spark from developing into a full fire while maintaining the simplicity of the overall connector structure.
3Reliability
If metal tube is used to bind conductor part, then electrical connection is secured, but heat generation may occur leading to fire risk
Solution Approach 1:
The fire-extinguishing powder serves as a protective intermediary between the metal tube (heat source) and the surrounding flammable materials. In the event that excessive heat is generated at the electrical connection point, the powder provides a fire-suppressing barrier that prevents the heat from igniting nearby materials, allowing the metal tube to maintain its electrical connection function without proportionally increasing fire risk.
