Inverting Head Nozzle Base Recess Fixing for Downsizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing component mounting apparatuses face challenges in achieving downsizing while maintaining mounting accuracy due to the need for a long downward movement stroke of the component, caused by the thickness of the nozzle base required for screwing the nozzle locking member, which increases the overall apparatus size.
Innovation Solution
The inverting head incorporates a nozzle holder with a nozzle base that supports both ends with a pair of fixing members, eliminating the need for screws to attach the nozzle locking member, allowing for a thinner nozzle base and reducing the downward movement stroke, thus enabling a more compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nozzle locking member is attached to the nozzle base by a screw, then the nozzle locking member can be securely fixed, but the nozzle base becomes thick and the downward movement stroke becomes long
Solution Approach 1:
The fixing mechanism is divided into two parts: a recess formed in the nozzle base and a fixing member that fits into the recess. This segmentation allows the locking member to be secured without requiring a thick nozzle base, thus reducing the downward movement stroke while maintaining secure fixation.
Solution Approach 2:
The fixing mechanism transitions from a depth-oriented screw attachment (requiring thick base) to a horizontal/planar recess-fit mechanism. By moving the fixing approach to another dimension (horizontal insertion rather than vertical threading), the nozzle base thickness is reduced while maintaining secure locking.
2Reliability
If the nozzle base is made thick to accommodate screw attachment, then the nozzle locking member can be securely fixed, but the whole apparatus size increases
Solution Approach 1:
The fixing mechanism is divided into a recess in the nozzle base and a separate fixing member. This segmentation enables secure locking without increasing the overall apparatus volume, as the fixing structure is integrated into the existing base geometry rather than adding external thickness.
Solution Approach 2:
The fixing approach changes from vertical screw penetration (increasing base thickness and apparatus volume) to horizontal recess-fit attachment (maintaining compact dimensions). This dimensional shift secures the locking member without expanding the apparatus footprint.
3Volume of moving object
If the downward movement stroke is shortened, then the apparatus can be downsized, but the mounting accuracy may be affected
Solution Approach 1:
The fixing mechanism is segmented into a recess and a fitting fixing member, enabling precise positioning with reduced stroke. This segmentation allows for accurate component placement within a compact structure, maintaining mounting precision while reducing overall apparatus size.
Solution Approach 2:
By changing the fixing dimension from vertical (affecting stroke length) to horizontal (recess-fit), the patent achieves short stroke without compromising mounting accuracy. The precision is maintained through the geometric constraint of the recess-fit mechanism rather than through stroke length.

Function Achieved in This Case
This configuration enhances mounting accuracy and achieves downsizing of the component mounting apparatus by shortening the downward movement stroke, preventing interference between the inverting head and the mounting head, and improving the overall apparatus dimensions.
