Trackball Device Segmented Casing for Ultrasonic Panel Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trackball devices in ultrasonic diagnostic apparatuses require professional maintenance and are cumbersome to clean, leading to impaired detection performance and reliability due to dirt accumulation, necessitating a solution that allows for easy cleaning without detaching the device from the operation panel.
Innovation Solution
A trackball device design featuring a first casing with a housing portion and a second casing with a ring portion that can be detached from the first casing using a dynamic action, allowing for easy ejection and cleaning of the ball without removing the upper plate or the trackball device from the operation panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trackball device is sealed within the casing to maintain structural integrity, then reliability is improved, but maintenance and cleaning become difficult requiring professional intervention
Solution Approach 1:
The trackball device is divided into two separable casings: a first casing containing the ball and detector, and a second casing with an opening portion. The second casing can be detached from the first casing, allowing users to access the ball and housing portion for cleaning without removing the entire device from the operation panel. This segmentation enables easy maintenance while preserving the sealed structure during operation.
2Device complexity
If the trackball device is integrated into the operation panel to simplify structure, then device complexity is reduced, but cleaning access becomes restricted requiring panel detachment
Solution Approach 1:
The device is segmented into a first casing and a second casing that can be separated. The second casing remains mounted on the operation panel while the first casing can be accessed by detaching the second casing from the first. This allows users to clean the ball and housing portion without removing the entire trackball device from the operation panel, maintaining structural integration while enabling easy cleaning access.
3Ease of operation
If the ball is partially exposed for operation, then ease of operation is improved, but dirt accumulation and dust in the housing portion increase
Solution Approach 1:
The device is divided into a first casing containing the ball and detector, and a second casing with an opening portion. The ball is partially exposed from the opening portion for easy operation, while the segmented structure allows users to detach the second casing and clean the ball and housing portion, preventing dirt and dust accumulation that would otherwise occur from continuous exposure.
