Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal lines for devices such as electrical equipment, electric vehicles, and mechanical control systems require separate power and signal transmission, leading to wiring difficulties, potential damage from errors, and challenges in waterproofing and mass production, especially with traditional connectors.
Innovation Solution
A transmission cable set featuring symmetrical male and female plugs with conductive interfaces and elastic sheets, allowing for quick and secure connection, preventing reverse wiring errors, and facilitating easy assembly and mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power lines and signal lines are configured, then power transmission and signal transmission can be achieved independently, but wiring complexity increases and the risk of wiring errors increases
Solution Approach 1:
The patent combines power transmission and signal transmission into a single integrated transmission cable system. The cable includes both power conductors and signal conductors within the same insulation layer, allowing simultaneous transmission of both power and signals through one cable rather than requiring separate cables for each function.
Solution Approach 2:
The patent employs asymmetric connector design where the male and female connectors have non-symmetrical contact arrangements. The signal contacts and power contacts are positioned at different locations and orientations, creating a keyed connection that prevents incorrect wiring through physical incompatibility of mismatched configurations.
2Object-affected harmful factors
If traditional waterproof connectors with special mechanisms are used, then waterproof performance is achieved, but manufacturing complexity increases and mass production becomes difficult
Solution Approach 1:
The patent uses an insulation layer that extends beyond the connector contacts to form a protective covering. This insulation layer acts as a waterproof barrier, sealing the connection interface without requiring complex mechanical waterproofing mechanisms such as buckles or special sealing structures.
Solution Approach 2:
The connector is designed with modular components including the insulation layer, metal shell, and contact elements that can be manufactured separately and assembled. This segmentation allows each component to be optimized for its specific function while simplifying the overall manufacturing process and enabling easier mass production.
3Adaptability or versatility
If additional signal lines or power lines are added through wiring, then transmission requirements are met, but construction difficulty increases and equipment may be damaged due to wiring errors
Solution Approach 1:
The transmission cable is designed with multiple conductors that can simultaneously carry power and various signal types. The cable structure supports both power transmission and data communication functions within a single integrated system, eliminating the need for separate wiring for different transmission requirements.
Solution Approach 2:
The cable is pre-configured with insulated conductors arranged in specific patterns before connection. The insulation layers and conductor arrangements are established during manufacturing, eliminating the need for complex field wiring and reducing the risk of construction errors during installation.
