Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for flash disks are prone to damage and signal instability due to repeated plugging and unplugging, leading to potential electric disconnection and unreliable data transmission.
Innovation Solution
A connector design featuring a shielding portion within the housing that protects the terminals from external forces, combined with a sandwich structure using wing portions and elastic pieces for enhanced mechanical strength and electrical conductivity, ensuring stable connections between the storage module and the connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connector structure is simplified for ease of assembly, then the assembly process becomes easier, but the connection strength and reliability deteriorate due to repeated plugging and unplugging
Solution Approach 1:
The connector housing is segmented into a body portion and a shielding portion that can be assembled separately. The shielding portion is subsequently crimped onto the storage module, dividing the assembly process into manageable stages that ensure proper positioning and secure connection without requiring complex one-step assembly procedures.
Solution Approach 2:
The shielding portion is first assembled to the connector body to form a pre-assembled unit with the terminals properly positioned. This preliminary assembly ensures that the terminals are correctly aligned and protected before the final crimping operation connects the connector to the storage module, improving both assembly ease and connection reliability.
2Strength
If the connector housing is made more robust to improve connection strength, then the mechanical strength improves, but the device size and complexity increase
Solution Approach 1:
The shielding function is extracted as a separate portion from the main connector body. This shielding portion can be independently manufactured and then crimped onto the storage module, allowing the main body to remain compact while the shielding portion provides the necessary mechanical strength and protection for the terminals.
Solution Approach 2:
The connector employs a composite structure combining the connector body material with the shielding portion material. The shielding portion is crimped onto the storage module to form a composite assembly that leverages the strengths of both materials - the body provides structural support while the shielding portion enhances connection strength and terminal protection.
3Ease of operation
If the terminals are exposed for easy connection, then the electrical connection becomes simpler, but the terminals become vulnerable to damage from external forces
Solution Approach 1:
The terminals are nested within the shielding portion which acts as a protective shell. The shielding portion encloses the terminals during the crimping process and maintains this protective configuration during use, allowing electrical connection while shielding the terminals from external mechanical forces that could cause damage.
Solution Approach 2:
The shielding portion serves as an intermediary structure between the external environment and the terminals. It transmits and distributes mechanical forces away from the vulnerable terminals while maintaining electrical connectivity, protecting the terminals from direct exposure to harmful external forces.
