SpO2 Sensor Binding Strap with Deformable Access Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding straps for SpO2 sensors are prone to being lost when not in use and tend to loosen during application, as they are not securely fixed to the user's position.
Innovation Solution
A binding strap design featuring a U-shaped main body with clamping portions and access openings that deform to securely hold the light emitting and receiving portions of the SpO2 sensor, along with a wrapping body that integrates into slots to prevent detachment and shifting, made from an elastically deformable material like silica gel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the binding strap is made from conventional non-deformable material, then the structure is simple and easy to manufacture, but the binding strap is prone to looseness during application and cannot securely hold the sensor components
Solution Approach 1:
The binding strap changes its physical state from rigid to elastically deformable, allowing it to dynamically adjust its shape and size during application. The elastic deformation enables the strap to conform to the user's body contours and securely hold the sensor components without slipping or loosening, while returning to its original shape when not in use.
Solution Approach 2:
The binding strap transitions from a static, fixed-structure design to a dynamic, adaptable structure. The elastically deformable material allows the strap to continuously adjust its configuration in response to external forces and body movements, maintaining secure holding capability throughout the application process.
2Reliability
If the binding strap is designed without attachment formations, then the device is simpler and easier to operate, but the binding strap is liable to be lost when temporarily not in use
Solution Approach 1:
The binding strap is divided into functional segments: the main body for wrapping, the attachment formation for securing to the sensor assembly, and the sensor mounting area. This segmentation allows the strap to be attached securely to the sensor components while maintaining ease of operation through simple attachment and detachment movements.
Solution Approach 2:
The attachment formation acts as an intermediary element between the binding strap and the sensor assembly. It provides a mechanical interface that enables secure attachment when needed while allowing easy detachment when the sensor is removed, preventing loss without complicating the overall operation.
3Reliability
If the access openings are designed with fixed size, then the manufacturing precision is easier to control, but the light emitting and receiving portions cannot pass through when the strap is not deformed
Solution Approach 1:
The access openings are designed with dimensions that change during elastic deformation. In the relaxed state, the openings are smaller to prevent accidental passage and ensure secure holding. During deformation, the openings expand to allow the light emitting and receiving portions to pass through, combining security with functionality.
Solution Approach 2:
The access openings transition from a static size to a dynamic dimension that adapts during application. The openings are small in the resting state to provide secure holding, but expand during elastic deformation to facilitate easy passage of the sensor components, eliminating the need for high manufacturing precision for fixed dimensions.
4Ease of operation
If the wrapping body is wound around a U-shaped main body, then the binding strap can be applied to the user, but the binding strap becomes loose during use
Solution Approach 1:
The binding strap utilizes elastic deformation to change its dimensional parameters during application. The strap is stretched and deformed during wrapping to fit around the user's body, and the elastic recovery force maintains tight holding stability, preventing loosening during use while preserving ease of application.
Solution Approach 2:
The binding strap transitions from a static wrapped structure to a dynamic elastic structure that continuously adjusts to maintain holding stability. The elastic material allows the strap to adapt to body movements and maintain consistent tension, preventing loosening while keeping the application process simple.

Function Achieved in This Case
The binding strap effectively secures the SpO2 sensor components, preventing loss and looseness by ensuring a tight fit through deformable access openings and integrated cable clamping grooves, maintaining the position of the sensor portions even when detached.

AI summary
A binding strap used in connection with a SpO2 sensor comprises two clamping portions each of which is provided with an access opening for passing the light emitting portion or light receiving portion of the SpO2 sensor and a holding recess for holding corresponding light emitting portion or light receiving portion, wherein said access openings are designed to allow corresponding light emitting portion or light receiving portion to pass only when said access openings are undergoing a certain amount of deformation. The binding strap of the present invention is advantageous in that the light emitting portion and the light receiving portion of the SpO2 sensor might be tightly secured to the binding strap, and the lost of the binding strap when not use is ensured to be hard.
