Dental Tool Tip Transfer Tool with Controlled Pushing Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent exchange of dental tool tips during treatments can negatively affect their lifetime and is difficult to attach properly, risking damage to the tool tip, instrument, or operator, especially with pointed ends like scalers.
Innovation Solution
A tool with a first receiving section and a first pushing element that allows for a precise, force-adjustable, translation-based movement to attach or detach dental tool tips via press-fit or force-fitting connections, without rotation, ensuring proper alignment and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual attachment of dental tool tip is performed by operator, then tool tip can be exchanged, but operator needs to provide sufficient force which risks damaging tool tip, instrument or operator
Solution Approach 1:
The patent introduces a transfer tool as an intermediary device between the operator and the dental tool tip. The transfer tool includes a receiving section that holds the tool tip and a pushing element that applies controlled force to attach or detach the tip. This intermediary mechanism eliminates the need for the operator to directly apply force to the pointed tool tip, thereby reducing the risk of damage to the tool tip, instrument, or operator while maintaining ease of operation.
2Adaptability or versatility
If frequent exchange of dental tool tips is performed, then different tool tips can be used during treatment, but lifetime of tool tip is negatively affected
Solution Approach 1:
The transfer tool allows for preliminary preparation of the tool tip in a safe, controlled environment before attachment to the instrument. The receiving section holds the tip securely during exchange, and the pushing element ensures proper alignment and gentle engagement. This preliminary action sequence enables frequent exchanges during treatment while minimizing mechanical stress and damage accumulation that would otherwise reduce tool tip lifetime.
3Reliability
If force is applied to attach dental tool tip, then tool tip can be secured to instrument, but improper force application can cause damage
Solution Approach 1:
The transfer tool controls the force application parameters through its mechanical design. The pushing element translates rotational or linear motion into controlled linear force along the tool tip's axis. The receiving section's geometry ensures proper alignment, and the pushing element's travel distance limits the maximum force applied. These parameter controls ensure reliable attachment while preventing excessive force that could damage the tool tip, instrument, or operator.

AI summary
A tool (1) for transferring a dental tool tip (10) between an assembled state and a disassembled state, the dental tool tip (10) - being arranged partially in an insert region of a dental instrument (30) in an assembled state, and - being removed from the insert region of the dental instrument (30) in a disassembled state, the tool (1) comprising -- at least a first receiving section (31) being configured to receive at least the insert region of the dental instrument (30) and at least a part of the tool tip (10) and -- at least a first pushing element (11) being configured to perform a first pushing movement, wherein by performing the first pushing movement, the first pushing element (11) causes a pushed movement (T) of the dental tool tip (10) to transfer the dental tool tip (10) from a first state to a second state, first and second states being distinct and chosen between the assembled state and the disassembled state, when at least the insert region and at least a part of the tool tip (10) are arranged in the first receiving section (31).
