Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed test sites with inertia test tables or chassis dynamometers are used to measure braking torque, then measurement precision is improved, but device complexity and loss of time increase due to the need to transport test vehicles to fixed locations
Solution Approach 1:
The patent transforms the fixed test site into a mobile testing platform by mounting the test system on a vehicle platform that can move to different locations. The testing equipment including force sensors, displacement sensors, and the brake system are integrated onto a mobile chassis, allowing the test system to dynamically relocate rather than requiring static vehicle transport to fixed sites
Solution Approach 2:
The patent introduces a mobile test platform as an intermediary between the test vehicle and the testing environment. This platform includes a brake system, sensor system, and data processing unit that mediates the measurement process, enabling accurate braking torque measurement without requiring the test vehicle to be transported to traditional fixed test sites
2Measurement precision
If fixed test sites with inertia test tables or chassis dynamometers are used to measure braking torque, then measurement precision is improved, but device complexity increases due to fixed installation requirements
Solution Approach 1:
The patent divides the traditional fixed test site infrastructure into modular components that can be independently assembled and disassembled. The test system is segmented into separate functional modules including the brake system, sensor array, data processing unit, and mobile platform, allowing flexible configuration and deployment without complex fixed installations
Solution Approach 2:
The patent transforms the static fixed test site infrastructure into a dynamic mobile system. The entire testing apparatus is mounted on a mobile platform with wheels, converting the fixed installation requirement into a mobile configuration that can be deployed at various locations, thereby reducing the complexity of permanent infrastructure
3Reliability
If traditional fixed test sites are used, then reliable braking torque measurement is achieved, but adaptability decreases when test vehicles cannot be transported to test sites
Solution Approach 1:
The patent creates a dynamic testing system that adapts to different locations by mounting all necessary components on a mobile platform. The system can reliably perform braking torque measurements at various sites including roadside locations, eliminating the constraint of fixed test site locations while maintaining measurement reliability
Solution Approach 2:
The patent designs a universal test platform that can accommodate different test vehicles and perform multiple testing functions. The mobile platform integrates the brake system, sensor array, and data processing capabilities into a single versatile unit that can test various vehicle types at different locations, enhancing both reliability and adaptability

AI summary
An inertia braking test system and a control method is provided, wherein the inertia braking test system is composed of an inertia brake test system, a sensor system and a tested object. An actuating device is connected with the inertia brake control device through a ball stud. The actuation function of the inertia brake control device with two degrees of freedom along the front-and-rear direction and the up-and-down direction of the vehicle is realized. The movable chassis realizes the mobile function of the system. The acceleration sensor can sense the acceleration of the movable chassis. Each force is tested by the first force sensor, the second force sensor and the third force sensor. The displacement data is measured by the first displacement sensor and the second displacement sensor, so that a movable brake system test is achieved.
