Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer air suspension systems lack remote operability, posing hazards during loading or unloading operations when the operator is not present to supervise height modifications.
Innovation Solution
A trailer vehicle function control system with a control valve operable by an electronic control unit, equipped with a standards-compliant wireless communication interface, allowing remote operation of air suspension and braking systems via a portable device, ensuring the device is within a safe distance from the trailer to prevent unauthorized access and ensure operator visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation of air suspension is enabled via wireless communication, then ease of operation is improved, but safety is worsened due to potential unauthorized access and lack of operator visibility
Solution Approach 1:
The patent introduces a wireless communication interface as an intermediary between the portable electronic device and the air suspension control system. This mediator enables remote operation while maintaining system safety through controlled communication protocols, allowing the operator to control trailer height from a distance without direct physical presence at the suspension controls.
Solution Approach 2:
The system implements feedback mechanisms where the electronic control unit monitors and responds to commands from the portable device. The system provides status information back to the operator, enabling informed remote operation. This feedback loop ensures that height modifications are executed as intended and allows the operator to maintain awareness of system state even when not physically present.
2Reliability
If signal strength is increased to improve wireless communication reliability, then ease of operation is improved, but security is worsened due to extended communication range allowing unauthorized access
Solution Approach 1:
The patent dynamically adjusts the signal strength parameter of the wireless communication interface based on operational requirements. By changing this physical parameter, the system optimizes communication reliability for remote operation while simultaneously limiting the communication range to prevent unauthorized access. The signal strength is modulated to achieve the necessary balance between operational effectiveness and security.
