Tool-Free Shield Connector with Resilient Locking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connector arrangements require tools or additional parts for fixation to a counterpart device, complicating the fastening process and potentially introducing bending forces.
Innovation Solution
A shield connector design featuring a housing with one or more locking elements that can engage automatically with counter locking elements on the device, eliminating the need for tools and providing secure fastening without screws, with optional secondary locking devices for secure disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods using bolts or screws are used to attach the shield connector to the counterpart device, then a secure connection is achieved, but the fastening process becomes complex and requires additional tools and parts
Solution Approach 1:
The locking element is designed to automatically engage with the counterpart device without requiring external tools or additional fastening parts. The resilient locking element deflects during insertion and automatically locks into position, making the system self-fastening and eliminating the need for manual intervention with tools.
Solution Approach 2:
The locking element is integrated directly into the housing structure, combining the fastening function with the connector body. This integration eliminates separate fastening components and simplifies the overall assembly, while still providing secure attachment through the resilient locking mechanism.
2Strength
If traditional screw fastening is used to connect the shield connector to the device, then a strong mechanical connection is achieved, but the fastening process becomes time-consuming and requires additional components
Solution Approach 1:
The resilient locking element automatically performs the fastening function during the insertion process itself. As the connector is inserted, the locking element deflects and then locks into the counterpart device, achieving both strong mechanical connection and rapid assembly in a single motion without requiring separate fastening steps.
Solution Approach 2:
The locking element is pre-configured in a resilient state that allows it to deflect during insertion and automatically lock into position. This preliminary resilient configuration enables the fastening action to occur naturally during the insertion process, eliminating the need for subsequent manual fastening operations.
3Reliability
If additional fastening parts like screws are used to establish connection, then a secure attachment is achieved, but the number of components increases and assembly becomes more complex
Solution Approach 1:
The locking element is merged with the housing as an integrated resilient structure. This combination eliminates the need for separate screws, bolts, or other fastening parts, reducing the total component count while maintaining secure attachment through the locking element's automatic engagement mechanism.
Solution Approach 2:
The housing with its integrated resilient locking element serves its own fastening function without requiring external fastening parts. The locking element's resilient nature allows it to automatically engage and secure the connector to the counterpart device, making the system self-sufficient and eliminating additional components.
