Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in securely and efficiently connecting uninsulated shield conductors to components like printed circuit boards, as existing connecting devices require complex handling and lack effective locking mechanisms to prevent undesired movement of the housing cover.
Innovation Solution
The electronic device incorporates a connecting device with a movable cover that securely holds the shield conductor in place, featuring a locking mechanism with a movable locking member and a blocking element to prevent unwanted movement, allowing for easy insertion and secure contact of the shield conductor without insulation, and is designed for simplified handling and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connecting device with a movable cover is used to securely hold the shield conductor, then the reliability of electrical contact is improved, but the device complexity increases due to the addition of locking mechanisms
Solution Approach 1:
The locking mechanism is divided into separate functional elements: a locking member with a blocking element that can move between locked and unlocked positions, and a cover that can move between open and closed positions. This segmentation allows each component to perform its specific function independently, ensuring reliable electrical contact while maintaining manageable complexity through modular design
Solution Approach 2:
The blocking element is designed to automatically block the locking member's movement from locked to unlocked position when the cover is in the closed position, without requiring additional actuation mechanisms. This self-service feature enhances reliability by preventing accidental disconnection while simplifying the overall mechanism by eliminating the need for separate control systems
2Stability of the object's composition
If locking means with a blocking element are added to prevent unwanted movement, then the stability of the connection is improved, but the ease of operation deteriorates due to additional steps required to access the shield conductor
Solution Approach 1:
The blocking element is pre-positioned to automatically engage when the cover moves to the closed position, securing the locking member before any operational use. This preliminary action ensures connection stability is established in advance, while the simple cover removal process maintains ease of operation when shield conductor access is needed
Solution Approach 2:
Instead of requiring active manipulation to unlock the connection, the design inverts the approach by using the cover's presence to automatically block the locking member's movement. This inversion ensures stability through passive mechanical blocking while maintaining operational simplicity through intuitive cover removal and replacement
3Object-affected harmful factors
If a cover is added to close the opening of the receiving space, then the protection against external influences is improved, but the manufacturing cost increases due to additional components
Solution Approach 1:
The cover serves multiple functions simultaneously: it protects the receiving space and shield conductor from external influences, provides a mounting surface for the locking mechanism, and acts as a user interface for accessing the shield conductor. This multi-functionality reduces the need for separate protective components, thereby lowering manufacturing costs while maintaining comprehensive protection
Solution Approach 2:
The protective cover is merged with the locking mechanism structure, where the cover's closure action directly engages the locking member and blocking element. This merging eliminates the need for separate protective housings or additional sealing components, reducing part count and manufacturing complexity while providing effective protection against external influences
