Adjustable Hose Support for Dental Instrument Arm Bending Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental care unit instrument arms do not allow for easy adjustment of bending resistance according to the weight of hand instruments, leading to inconsistent user experience due to varying instrument weights and personal preferences.
Innovation Solution
The instrument arm's bending resistance is adjusted by varying the position of the hose support relative to the arm, allowing for customizable removal resistance through adjustable positioning of the support organ along the instrument arm, which can be implemented using a mechanism like an eccentric trunnion and locking system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the instrument arm uses a fixed bending resistance design, then the structure is simple, but the removal resistance cannot be adjusted for different instrument weights
Solution Approach 1:
The hose support is made movable along the instrument arm, allowing the bending resistance to be dynamically adjusted by changing the support position. This enables the same instrument arm to adapt to different instrument weights without requiring multiple fixed-resistance arms, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The bending resistance parameter is changed by varying the position of the hose support along the instrument arm. By adjusting this positional parameter, the removal resistance can be optimized for different instrument weights, achieving adaptability without complex mechanisms.
2Ease of operation
If the hose support is positioned far from the instrument arm, then the removal resistance is low, but the hose may become loose and interfere with operations
Solution Approach 1:
The hose support position is made adjustable rather than fixed, allowing users to dynamically optimize the position based on the specific instrument being used. This resolves the contradiction by enabling the system to adapt to different scenarios - positioning the support to achieve appropriate hose tension and removal resistance for each case.
3Object-generated harmful factors
If the hose support is positioned close to the instrument arm, then the removal resistance is high, but it requires excessive force to remove instruments
Solution Approach 1:
The adjustable hose support allows users to move the support to positions that optimize removal resistance for different instrument weights. This dynamic adjustment capability resolves the contradiction by enabling the system to achieve appropriate hose tension without requiring excessively high removal resistance that would hamper instrument removal.
