Blood Oxygen Sensor Sealing Tape Design for Hermetic Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood oxygen sensors face issues with poor sealing due to manual application of waterproof paper and adhesive, leading to inefficiencies in production and high costs, especially when dealing with the height of light emitters and receivers, resulting in inadequate waterproofing and increased operational costs.
Innovation Solution
A sensor design utilizing a sealing tape with preformed folding lines that can be folded and adhered to hermetically wrap electronic components, including a method of using sub adhesive tapes to simplify the manufacturing process, allowing for improved sealing and automation suitable for mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual pasting of waterproof paper and adhesive is used, then the sealing process can be completed, but the sealing quality is poor and production efficiency is low
Solution Approach 1:
The sealing tape is divided into multiple functional areas (first side area, middle area, second side area) with pre-formed first and second folding lines, allowing each area to be folded and adhered separately to achieve comprehensive sealing of the light emitter and light receiver
Solution Approach 2:
The first and second folding lines are pre-formed on the sealing tape before use, and the tape is designed with predetermined folding directions and adhesion sequences, enabling automated folding and adhering processes without manual intervention
2Reliability
If manual pasting operation is used, then the process can be completed, but the operation cost is high
Solution Approach 1:
The sealing tape is segmented into distinct functional regions with pre-formed folding lines, enabling automated processing and reducing dependency on manual skilled labor, thereby lowering manufacturing costs while maintaining sealing reliability
Solution Approach 2:
The sealing tape is designed to be self-adhering through its structure, where the first side area adheres to the middle area and the second side area adheres to the first side area in a predetermined sequence, eliminating the need for separate adhesive application steps and reducing labor costs
3Area of stationary object
If waterproof paper is pasted layer by layer, then coverage can be achieved, but openings appear at edges due to component height
Solution Approach 1:
The sealing tape utilizes three-dimensional folding along first and second folding lines to wrap around the light emitter and light receiver, transitioning from a two-dimensional planar coverage to a three-dimensional conformal seal that accommodates component heights without edge openings
Solution Approach 2:
The sealing tape is designed as a flexible thin film structure that can be folded and wrapped around the electronic components, providing conformal coverage that adapts to the height and shape of the light emitter and light receiver, ensuring complete edge sealing

AI summary
A sensor includes a sealing tape having a first folding line and a second folding line, and an electronic component adhered to a middle area between the first folding line and the second folding line. A first side area of the sealing tape is folded along the first folding line and adhered to the middle area to cover the electronic component. A second side area of the sealing tape is folded along the second folding line and adhered to the first side area to hermetically wrap the electronic component in the sealing tape.
