Nozzle Replacement Table Unit One-Hand Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing nozzle replacement table unit requires operators to hold the nozzle holding member with one hand and operate the movable locking section with the other, leading to poor operability when attaching or detaching the nozzle.
Innovation Solution
The nozzle replacement table unit includes a nozzle container with an integrated operation section that allows operators to detach the nozzle container from the pedestal by releasing the fixing mechanism with one hand, improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation section is located on the base member separate from the nozzle holding member, then the fixing mechanism can be operated with one hand, but the operator must use both hands to attach or detach the nozzle holding member, resulting in poor operability
Solution Approach 1:
The operation section is integrated into the nozzle holding member itself, merging the function of holding nozzles with the function of operating the fixing mechanism. This allows the operator to detach the nozzle holding member by simply pulling it, without needing to separately operate a locking mechanism with the other hand, thereby improving operability.
2Reliability
If the movable locking section is swingable to engage with the nozzle holding member, then secure fixing is achieved, but the attachment and detachment process becomes complex requiring coordinated two-handed operation
Solution Approach 1:
The nozzle holding member is designed to automatically engage with the movable locking section through its own movement. When the operator pulls the nozzle holding member for detachment, the relative motion automatically disengages the locking mechanism without requiring the operator to manually operate it, making the system self-servicing and improving ease of operation while maintaining reliability.
