Drill Package Locking Structure for Sterile Edge Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill packaging solutions fail to provide easy handling during connection to a tool holding fixture while maintaining sterility and preventing contamination from packaging material contact with the cutting edges.
Innovation Solution
A package design with a protecting portion that houses the cutting portion in a contact-free manner and a locking portion that holds the tool engaging portion, allowing for a relative movement between the two portions to facilitate easy installation into a tool holding fixture without direct contact with the cutting edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drill is held in a contact-free manner in the package, then sterility is maintained and cutting edges are protected from contamination, but the package becomes more complex and handling during installation becomes difficult
Solution Approach 1:
The package is divided into a protecting portion (with first and second subportions) and a locking portion, each serving distinct functions. The protecting portion maintains contact-free housing for sterility, while the locking portion provides secure attachment, allowing independent optimization of each segment for its specific purpose.
Solution Approach 2:
The package incorporates movable elements including the first subportion that can be pressed toward the second subportion, and the locking portion that can move relative to the protecting portion. This dynamic design enables transition from a closed sterile state to an open installation state while maintaining protection throughout the process.
2Reliability
If the drill is secured firmly in the package to prevent movement and contamination, then protection is improved, but release and connection to tool holding fixture becomes more difficult
Solution Approach 1:
The package is pre-configured with a locking portion and protecting portion that can move relative to each other. This preliminary arrangement allows the user to simply press the first subportion toward the second subportion to initiate the release sequence, eliminating the need for complex manual manipulation during installation.
Solution Approach 2:
The movable interface between the locking portion and protecting portion acts as an intermediary mechanism. It mediates between the firmly secured state (for protection) and the release state (for installation), allowing controlled transition without direct contact with the cutting edges.
3Object-affected harmful factors
If a protective cap is used to cover the cutting edges, then contamination is prevented, but the package structure becomes more complex and handling cumbersome
Solution Approach 1:
The protective function is merged with the structural framework of the package itself. The protecting portion with its first and second subportions serves both as the package structure and as the protective barrier, eliminating the need for a separate protective cap while maintaining protection functionality.
4Ease of operation
If the package allows easy release of the drill, then installation becomes simpler, but sterility protection may be compromised
Solution Approach 1:
The locking portion is extracted as a separate functional element that can move independently relative to the protecting portion. This extraction allows the easy release function to be isolated in the locking mechanism, while the protecting portion maintains its sterile enclosure until the final installation moment.

AI summary
The invention relates to a package for a drill. The package has a protecting portion arranged to house a cutting portion of said drill in a contact free manner and a locking portion arranged to hold a tool engaging portion of said drill. The locking portion and the protecting portion are movable relative each other and the drill is releasable from the locking portion by a movement of the locking portion relative the protecting portion. The protecting portion is allows the user to clamp the cutting portion of said drill by pressing the protecting portion and thereby establishing a contact between the protecting portion and the cutting portion of said drill. The invention also relates to a method and an arrangement.
