Floating Plate Brake Meter for Braking Force and Weight Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plate brake meters cannot accurately measure the vertical weight component of a vehicle, which is crucial for determining the effectiveness of braking forces, as they are designed to read forces only in a horizontal direction, limiting their ability to assess the braking system's performance and the functionality of suspension components.
Innovation Solution
A plate brake meter with floating supports featuring double dynamometers and weight sensors at strategic points, allowing for accurate measurement of both braking forces and vehicle weight, with a die-cut plate design that ensures load distribution to sensors, and reinforced mobile supports to prevent distortion and buckling, enabling comprehensive assessment of braking performance and suspension functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed frame structures are used in plate brake meters, then structural stability is improved, but the ability to measure vertical weight component is lost
Solution Approach 1:
The fixed frame structure is segmented into a mobile upper part supported by multiple independent sensors. The upper part is divided into sections that can move independently on the lower part, allowing weight measurement through sensor readings while maintaining structural stability through the segmented configuration.
Solution Approach 2:
Sensors are introduced as intermediary elements between the mobile upper part and the lower part. These sensors (including double dynamometers) act as mediators that transmit and measure both vertical weight components and horizontal braking forces, enabling simultaneous measurement of both components without requiring a completely fixed or completely mobile structure.
2Measurement precision
If sensors are positioned to measure static weight, then weight measurement accuracy is improved, but dynamic braking force measurement is compromised
Solution Approach 1:
The double dynamometers are designed to perform multiple functions: they measure both the static weight component (vertical force) and the dynamic braking force (horizontal force). This multi-functionality allows a single sensor system to accurately capture both weight and braking force data without compromising either measurement's reliability.
Solution Approach 2:
The sensor system is designed to be dynamic rather than static. The mobile upper part can move freely on the lower part, allowing the sensors to respond dynamically to both static weight loads and dynamic braking forces. This dynamic configuration ensures accurate measurement of both stationary weight and moving braking forces.
3Strength
If the mobile upper part is made thick and rigid, then structural strength is improved, but sensor measurement accuracy is reduced due to load distribution
Solution Approach 1:
The mobile upper part is designed with non-uniform thickness and reinforcement only where structurally necessary. The plates are thicker and reinforced at the ends where sensors are located to ensure proper load transmission to the sensors, while being thinner in intermediate sections to minimize load distribution effects. This local quality approach maintains structural strength at critical points while preserving sensor measurement accuracy.
