Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic component installing devices face challenges in miniaturizing nozzle holders and improving filtration performance due to restricted filter sizes and poor workability during maintenance, especially with the miniaturization of electronic components.
Innovation Solution
The design incorporates a cartridge with a filter holding body, annular packing, and a pad to securely connect suction paths, allowing for a compact nozzle holder configuration that enables easy attachment and detachment of the cartridge, reducing the size of the nozzle holder and enhancing filtration performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter size is increased to improve filtration performance, then the filtration efficiency is improved, but the nozzle holder size increases and workability during maintenance deteriorates
Solution Approach 1:
The device is divided into separate functional modules: the nozzle holder (19) that attaches to the main shaft and the cartridge (60) that contains the filter (62). This segmentation allows the filter to be optimized for filtration performance while the nozzle holder remains compact for good workability. The cartridge can be easily attached and detached from the nozzle holder, enabling maintenance without removing the entire assembly.
2Ease of operation
If the nozzle holder size is reduced to improve workability, then the ease of operation is improved, but the filter size is restricted and filtration performance deteriorates
Solution Approach 1:
The cartridge (60) containing the filter (62) is designed to be inserted into and nested within the nozzle holder (19). This nesting arrangement allows a relatively large filter to be housed within the compact nozzle holder structure. The cartridge serves as a container that fits inside the nozzle holder, enabling the filter to maintain adequate size for good filtration performance while the overall nozzle holder remains small for excellent workability during attachment and detachment operations.
3Reliability
If the filter is integrated into the nozzle holder to improve filtration performance, then the filtration efficiency is improved, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The device is divided into separate functional modules: the nozzle holder (19) that attaches to the main shaft and the cartridge (60) that contains the filter (62). This segmentation allows the filter to be optimized for filtration performance while the nozzle holder remains compact for good workability. The cartridge can be easily attached and detached from the nozzle holder, enabling maintenance without removing the entire assembly.
Solution Approach 2:
The cartridge (60) serves multiple functions: it houses the filter (62), provides a connection interface with the nozzle holder (19), and enables easy maintenance through detachable design. The nozzle holder itself is a multi-functional component that attaches to the main shaft, holds the cartridge, and facilitates easy attachment and detachment operations. This multi-functionality reduces overall device complexity while maintaining good filtration performance.
4Ease of repair
If the cartridge is made detachable to improve maintenance ease, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The cartridge (60) serves multiple functions: it houses the filter (62), provides a connection interface with the nozzle holder (19), and enables easy maintenance through detachable design. The nozzle holder itself is a multi-functional component that attaches to the main shaft, holds the cartridge, and facilitates easy attachment and detachment operations. This multi-functionality reduces overall device complexity while maintaining good filtration performance.

AI summary
A nozzle holder is configured to include an insertion hole for inserting and storing a cartridge from an entrance thereof, a tubular holder tube portion having a vent hole for introducing a negative pressure into the insertion hole, and a clamp lever in which an engaging portion engaged with an engaged portion of the nozzle inserted into the insertion hole in a state where the entrance of the insertion hole is blocked, is formed. Accordingly, when the nozzle is detached from the nozzle holder, the clamp lever prevents the cartridge from coming off the insertion hole by being displaced toward the insertion hole.
