Hinge Connector With Rotating Second Connector For High Current
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors in display devices are inadequate for handling high current requirements for power voltages, leading to reduced signal transmission pads and increased cable and connector counts, and can cause wire melting due to insufficient wire widths.
Innovation Solution
A connector design with a hinge mechanism and rotating second connector, featuring wider voltage pads and signal pads, allowing increased current capacity and preventing wire overheating by distributing signal and voltage wires effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the width of voltage pads is extended to increase allowable current for power voltages, then the current capacity is improved, but the number of signal transmission pads is reduced
Solution Approach 1:
The connector is divided into multiple separate connectors (first connector and second connector) that can be independently designed. This segmentation allows each connector to have optimized pad configurations - voltage pads in one connector and signal pads in another, eliminating the need to compromise between voltage and signal pad requirements in a single connector.
Solution Approach 2:
A cable is introduced as an intermediary component between the first and second connectors. This cable carries both the high-current power voltage signals and the data signals, allowing the connectors to be specialized for their respective functions while maintaining complete signal and power transmission capability through the combination of connector-cable-connector chain.
2Power
If the width of wires in the cable is increased to prevent melting from heat, then the current carrying capacity is improved, but the cable weight and space requirements increase
Solution Approach 1:
The cable is segmented into separate voltage wires and signal wires, with each wire optimized for its specific function. The voltage wires have sufficient width for high current carrying capacity, while the signal wires can be thinner since they carry low-current data signals. This segmentation allows the cable to achieve the required power transmission capability without the excessive weight that would result from making all wires uniformly thick.
3Quantity of substance
If the number of cables and connectors is increased to maintain signal transmission capability, then the signal transmission capacity is improved, but the device complexity and cost increase
Solution Approach 1:
The system is segmented into specialized components (first connector for voltage, second connector for signals, cable with separated wires) that work together to achieve complete transmission capability. This segmentation actually reduces overall complexity by allowing each component to be optimized and standardized for its specific function, rather than requiring a single complex connector to handle all functions.
