Integrated Biological Signal Detection Device with Segmented Fixing Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information detection devices, such as heartbeat measurement devices, face instability in detection performance due to detachable electrical connections, which can lead to mechanical separation and damage from external forces and cleaning solutions, affecting the electrode and electrical connection portions.
Innovation Solution
A biological information detection device with a device main body and biological signal detection portion integrated with a fixing portion that covers and secures the device to the body, preventing external forces and allowing for easy maintenance, using a combination of elastic and non-elastic straps or belts for secure adhesion and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the main body portion and the electrode are formed detachably to each other for maintenance purposes, then the ease of maintenance is improved, but the reliability of electrical connection deteriorates due to mechanical separation and damage from repeated attaching and detaching operations
Solution Approach 1:
The device is divided into three separable components: the fixing portion (strap), the device main body, and the biological signal detection portion. This segmentation allows the strap to be detached for cleaning without exposing electrical parts to cleaning solutions, while maintaining reliable electrical connections within the integrated device main body and detection portion.
Solution Approach 2:
The biological signal detection portion with electrodes is extracted as a separate component that can be fixed to the body surface independently from the strap. This extraction prevents the electrical connection portion from being exposed to cleaning solutions during strap maintenance, thereby protecting the reliability of electrical connections.
2Ease of operation
If the strap is provided with an electrode for direct contact with the body, then the ease of operation is improved, but the reliability deteriorates due to external tensile forces causing mechanical separation of the electrical connection portion
Solution Approach 1:
The device separates the fixing function (strap) from the signal detection function (biological signal detection portion with electrodes). The detection portion is fixed directly to the body surface, eliminating tensile forces on electrical connections while maintaining ease of operation through direct skin contact for accurate signal acquisition.
3Ease of repair
If the electrical connection portion is made detachable for cleaning the strap, then the ease of maintenance is improved, but the manufacturing precision deteriorates due to instability in detection performance from varying installation conditions
Solution Approach 1:
The device structure segments the strap from the detection portion, allowing the strap to be removed for cleaning while the detection portion remains fixed to the body with stable electrode positioning. This ensures consistent detection performance without requiring reinstallation of electrical connection portions.

AI summary
A biological information detection device has a device main body and a biological signal detection portion formed integrally with the device main body. The biological signal detection portion has at least one electrode for contacting a biological surface of a human body. A fixing portion has an elastic strap and is configured to mount the device main body and the biological signal detection portion to the human body without the device main body and the biological signal detection portion being directly attached to the elastic strap. The fixing portion covers the device main body and the biological signal detection portion with the electrode being disposed in contact with the biological surface of the human body when the device main body and the biological signal detection portion are mounted to the human body.
