Integrated Tablet Cutting Blade Replacement Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet cutting blade replacement jigs require separate attachment and detachment jigs, making it difficult to re-attach blades for inspection or cleaning, especially in dispensing sites without assisting devices, and do not allow easy exposure of cutting edges for examination or cleaning.
Innovation Solution
A tablet cutting blade replacement jig with a plate-shaped body having notches to hold blades, allowing easy attachment and detachment, and featuring manually operated retention members to switch between holding and releasing states, enabling easy handling and inspection of cutting edges without removing the blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate attachment and detachment jigs are used, then blade replacement is facilitated, but device complexity increases and ease of operation decreases when re-attaching blades for inspection
Solution Approach 1:
The patent combines the attachment jig and detachment jig into a single integrated replacement jig. The jig main body includes a jig opening that can receive both the falling tablet guiding member and tablet cutting blades simultaneously, eliminating the need for separate attachment and detachment jigs. This merging allows the same jig to perform both attachment and detachment functions, reducing device complexity while maintaining ease of operation for blade re-attachment.
2Reliability
If blades are held securely in the jig, then safe handling is improved, but ease of operation decreases when inspection or cleaning is needed
Solution Approach 1:
The patent employs a retention member that can switch between retention and release states dynamically. The retention member is configured to hold the tablet cutting blades securely in the jig during handling and transport, but can be manually operated to release the blades when inspection or cleaning is required. This dynamic retention mechanism allows the cutting edges to be accessed without permanently removing blades from the jig, maintaining safe handling while improving ease of operation for maintenance tasks.

AI summary
Attachment/detachment of tablet cutting blades to/from a tablet cutting blade replacement jig inserted into and withdrawn from a tablet splitting apparatus to receive and deliver the tablet cutting blades is facilitated even in a dispensing site. The cutting edges of the tablet cutting blades are allowed to be exposed without detaching the tablet cutting blades. The tablet cutting blade replacement jig (60) includes: a jig main body (61) that can be inserted into and withdrawn from support members (28) in place of a falling tablet guiding member; blade holders (64) for retaining tablet cutting blades (41) within notches (63) of the jig main body (61); operating members (72) that are manually operated to switch between maintenance and release of retention of the tablet cutting blades; and urging members for maintaining the switched state even though the switched state is on a retention maintained side or is on a retention released side. Two openable-closable plate-shaped bodies (61a and 61b) are disposed in the jig main body (61), and the tablet cutting blades (41) are held with their cutting edges oriented toward inward surfaces of the two plate-shaped bodies (61a and 61b) in a closed state.
