Safety Belt Heating Assembly with Integrated PCB Protector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety belts are brittle in cold weather, reducing their safety performance and comfort for passengers, as they absorb body heat when in contact with the passenger.
Innovation Solution
A safety belt body with a heating assembly integrated into the tubular webbing, comprising a first printed circuit board for temperature monitoring and a second printed circuit board for signal transmission, secured within a protector housing that protects electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a heating assembly is integrated into the safety belt, then passenger comfort and safety belt flexibility are improved, but device complexity increases
Solution Approach 1:
The heating assembly is integrated into the tubular webbing structure, merging the heating function with the existing safety belt structure. The first and second printed circuit boards are combined within a single protector housing, reducing the number of separate components and simplifying the overall device.
Solution Approach 2:
The heating assembly serves multiple functions: it heats the safety belt to improve passenger comfort, maintains flexibility of the webbing in cold weather, and prevents the safety belt from absorbing body heat. The protector housing simultaneously protects electronic components and provides structural support.
2Device complexity
If electronic components are exposed, then device complexity is reduced, but reliability decreases due to impact, moisture, and corrosion
Solution Approach 1:
The first and second printed circuit boards are nested within the protector housing, which is integrated into the tubular webbing structure. This nested arrangement protects the electronic components from external environmental factors while maintaining a compact design.
Solution Approach 2:
The protector housing acts as an intermediary barrier between the electronic components and the external environment. It protects the printed circuit boards from impact, moisture, and corrosion while allowing the heating assembly to function properly.
3Manufacturing precision
If the heating assembly is secured with adhesive, then manufacturing precision is improved, but ease of manufacture decreases
Solution Approach 1:
The adhesive is applied in advance to secure the heating assembly to the tubular webbing before final assembly. This preliminary bonding action ensures proper positioning and alignment of components, improving manufacturing precision while streamlining the assembly process.
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
The heating assembly maintains optimal temperature, enhancing passenger comfort and safety belt flexibility, while the protector housing extends the service life by protecting components from impact, moisture, and corrosion.
Implementation Method 1
a heating wire arranged along the length direction of the base body and secured to the base body
Implementation Method 2
the heating assembly is secured to the webbing via an adhesive, and the adhesive is applied to one or both sides of the heating assembly
