Fixing Device for Needle Elements Using Groove and Pressing Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronics manufacturing techniques lack a precise method to position and fix needle-shaped elements, such as welding wires, leading to reduced welding precision and product quality due to manual positioning and fixing.
Innovation Solution
A fixing device with a positioning groove and pressing protrusion mechanism, comprising links and pivot shafts, allows for precise positioning and reliable holding of needle-shaped elements, utilizing a spring mechanism for automatic opening and closing to facilitate easy insertion and secure retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual positioning and fixing of needle-shaped elements is used, then device complexity is reduced, but manufacturing precision and reliability deteriorate
Solution Approach 1:
The fixing device is segmented into distinct functional components: a fixing base with positioning groove, a fixing mechanism with pressing protrusion, and linkages. This segmentation allows each component to perform its specific function (positioning, pressing, moving) independently, achieving precise positioning without excessive overall complexity
Solution Approach 2:
The fixing mechanism incorporates a spring that automatically returns the pressing protrusion to its initial position after the needle-shaped element is inserted. This self-service feature eliminates the need for manual resetting or complex control systems, maintaining simplicity while ensuring reliable positioning
2Device complexity
If manual positioning and fixing of needle-shaped elements is used, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The positioning groove is pre-formed in the fixing base with precise dimensions and geometry designed to accommodate the needle-shaped element. This preliminary preparation ensures that when the element is inserted, it is automatically positioned correctly without requiring complex adjustment mechanisms during operation
Solution Approach 2:
The spring-loaded pressing protrusion automatically engages with the needle-shaped element upon insertion and self-adjusts to apply consistent pressing force. This self-service mechanism ensures reliable fixing without requiring external control or complex actuation systems
3Manufacturing precision
If a fixing mechanism with links and springs is used, then positioning precision is improved, but ease of operation worsens
Solution Approach 1:
The fixing mechanism merges multiple functions into a single integrated assembly: the links connect the pressing protrusion to the fixing base, while the spring provides automatic resetting. This merging allows the operator to simply insert and remove the needle-shaped element without needing to manually manipulate separate components, maintaining ease of operation despite the complex internal mechanism
