Biological Signal Clothing Wiring Layout for Comfort and Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothing for biological signal measurement face issues of discomfort due to direct contact of wirings with insulating materials causing sweat accumulation and heat rush, and inadequate conductivity and insulation when wirings are covered on the outer surface.
Innovation Solution
The clothing design arranges wirings on the outer surface of the clothing main body part, using a cutout or hollow structure to expose them to metal connectors while being covered by insulating materials, ensuring direct contact with the back material of the metal connector for conductivity and complete insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wirings are covered with waterproof insulating material on the skin side surface, then insulation from skin is improved, but wearing comfort deteriorates due to sweat accumulation and heat rush
Solution Approach 1:
The patent inverts the conventional arrangement by placing the waterproof insulating material on the outer surface side of the clothing instead of the skin side surface. The wiring penetrates the clothing main body part to make contact with the metal connector, while the insulating material covers the wiring on the outer surface. This inversion maintains insulation performance while eliminating direct contact between the insulating material and skin, thereby improving wearing comfort by preventing sweat accumulation and heat rush.
2Object-affected harmful factors
If wirings are arranged on the outer surface side, then wearing comfort is improved, but conductivity to metal connector deteriorates due to insulation requirements
Solution Approach 1:
The patent applies local quality by creating different functional zones: the wiring is exposed on the skin side surface to ensure direct contact and good conductivity with the metal connector, while the wiring is covered with waterproof insulating material on the outer surface side to provide insulation. This localized differentiation of insulation coverage allows the wiring to achieve both good electrical contact where needed and insulation where required, resolving the contradiction between comfort and conductivity.
3Strength
If metal connector penetrates fabric to deform inside front material, then fixing strength is improved, but wiring insulation deteriorates due to direct contact with metal
Solution Approach 1:
The patent segments the insulating material coverage into two parts: the wiring is exposed in the region where the metal connector penetrates the fabric to ensure direct contact and good electrical connection, while the insulating material covers other portions of the wiring on the outer surface. This segmentation allows the metal connector to maintain strong fixing strength through fabric penetration while the insulating material provides insulation protection in non-contact regions, resolving the contradiction between fixing strength and insulation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design provides comfortable wear, reduces steamy feeling, prevents abrasion, and maintains high conductivity and insulation properties, allowing easy attachment and detachment of the electronic device.
Implementation Method 1
the wiring is required to be covered with a waterproof insulating material because contact with skin or other objects introduces noise into the biological signals
Implementation Method 2
bringing the wiring into direct contact with the metal connector over a large area is important to achieve sufficient electric conductivity of the wiring to the metal connector
