Pharmacy Jar Quick-Thread Lid and Base for Fast Lifting Arm Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of pharmacy recipe-making jars on conventional devices is cumbersome and time-consuming due to the need for long screwing distances and the risk of cross-threading, which can damage threads and increase handling time.
Innovation Solution
A pharmacy recipe-making jar with a lid or base featuring externally threaded areas spaced apart, allowing for quick-threading attachment to a lifting arm with internally threaded areas, reducing the rotation distance to 90° or less, and a lifting arm design with a recess for secure clamping, minimizing tilting and force required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional single-thread attachment is used, then thread engagement is simple, but screwing distance is long and handling time increases
Solution Approach 1:
The attachment mechanism is segmented into multiple circumferentially spaced threaded portions (at least two) on both the jar lid/base and the lifting arm. This segmentation allows the jar to be attached by rotating only 90 degrees or less instead of requiring a full 360-degree rotation, significantly reducing attachment time and improving operational efficiency.
2Reliability
If long screwing distance is required, then thread engagement is secure, but cross-threading risk increases and thread damage may occur
Solution Approach 1:
Multiple circumferentially spaced threaded portions are provided on both the jar lid/base and lifting arm. The unthreaded intermediate areas between these portions act as alignment guides that prevent cross-threading by ensuring the threaded portions engage correctly from the start. This segmentation maintains secure thread engagement while minimizing the risk of cross-threading and thread damage.
3Ease of operation
If conventional attachment method is used, then structural design is simple, but attachment and detachment require considerable effort
Solution Approach 1:
The attachment mechanism uses multiple circumferentially spaced threaded portions with unthreaded intermediate areas. This segmented design reduces the rotation distance required for attachment to 90 degrees or less, significantly reducing the effort required while maintaining a relatively simple structural implementation.
Solution Approach 2:
The unthreaded intermediate areas act as intermediaries that facilitate easy insertion and alignment of the jar lid or base onto the lifting arm. These unthreaded portions guide the threaded areas into proper engagement, reducing the effort required for attachment while maintaining structural simplicity.
4Ease of manufacture
If single threaded area is used, then manufacturing is simple, but attachment speed is slow
Solution Approach 1:
Multiple circumferentially spaced threaded portions are provided on both the jar lid/base and lifting arm. This segmented approach increases attachment speed by reducing the rotation distance to 90 degrees or less, while the manufacturing complexity remains relatively low as each threaded portion can be produced using standard threading processes.
