Fingerstall Oximeter Segmented Case and Soft Gum Coat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fingerstall oximeters are not robust, have complex assembly processes, and have short battery life due to small battery compartments, making them difficult to use and maintain, especially for older users.
Innovation Solution
A fingerstall oximeter design featuring a separate case for circuit elements with a battery and circuit board chamber, a soft gum coat for protection and comfort, and a buckle and screw mechanism for easy assembly and maintenance, along with a sliding battery cover for convenient battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the soft gum coat and case are formed integrally as one piece, then the structure is simpler, but the assembly becomes more complex and robustness decreases
Solution Approach 1:
The oximeter is divided into separate components: a soft gum coat and a hard case, which are assembled together rather than formed as one integral piece. This segmentation allows each component to be optimized independently - the soft gum coat for comfort and the hard case for protection - while simplifying the manufacturing and assembly process.
2Device complexity
If a single metal fender is used for mounting elements, then the structure is simpler, but the assembly becomes more complex and robustness decreases
Solution Approach 1:
The mounting bracket and the case are merged into a single integrated component. The case itself serves as the mounting structure for the measurement elements and circuit boards, eliminating the need for separate mounting brackets and simplifying the overall assembly while improving structural robustness.
3Volume of stationary object
If a small battery compartment is used, then the device volume is smaller, but the battery life is shortened
Solution Approach 1:
The battery compartment is designed with an optimized three-dimensional layout that efficiently utilizes available space. By arranging the battery and associated components in a compact yet spacious configuration, the design accommodates larger batteries without significantly increasing the overall device volume, thereby extending battery life while maintaining portability.
4Reliability
If the battery cover is strongly combined with the oximeter, then the structure is more robust, but it becomes difficult for users to replace batteries
Solution Approach 1:
The battery cover is designed with a dynamic opening mechanism that allows it to be securely attached during normal use but easily opened when needed. The cover can be flipped open to reveal the battery compartment, providing a balance between structural robustness and user-friendly battery replacement capability.
