Dispensing Device Dual Spring Contact Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices face challenges in precisely detecting the contact of a chip attaching member with a dispensing chip while maintaining sufficient shock absorption, as reducing the elastic force of the spring compromises the cushion effect during attachment operations.
Innovation Solution
A dispensing device with a dual elastic member system, where a first elastic member with a lower spring constant and a second elastic member with a higher spring constant work in conjunction with a detector to ensure precise contact detection and adequate shock absorption by adjusting the energizing forces during the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the elastic force of the spring is reduced to enable precise contact detection, then the detection precision is improved, but the shock absorbing capability deteriorates
Solution Approach 1:
The patent divides the single spring system into two separate springs: a first spring with lower elastic force for detection purposes, and a second spring with higher elastic force for shock absorption. This segmentation allows each spring to be optimized for its specific function, resolving the contradiction between detection precision and shock protection
Solution Approach 2:
The patent implements a dual-spring configuration where the first spring provides preliminary cushioning for gentle contact detection, while the second spring provides additional cushioning for shock absorption during forceful attachment operations. This beforehand cushioning approach ensures both detection sensitivity and impact protection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual elastic member system enables precise detection of the chip attaching member's contact with the dispensing chip while providing a significant cushion effect, preventing damage during attachment and enhancing operational precision and safety.
Implementation Method 1
a first elastic member for suppressing a movement of the chip attaching member with respect to the base; a second elastic member serving to suppress the movement of the chip attaching member with respect to the base and having a greater elastic constant than an elastic constant of the first elastic member
