Road Module Eccentric Roller Lid Speed Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-speed restricting devices for roadways, such as speed bumps, are prone to mechanical stress, fatigue, and damage from heavy vehicles and adverse weather conditions, affecting both vehicles and the devices themselves, and are not effectively designed to differentiate between legal and illegal speed violations.
Innovation Solution
A robust road module with an elongated container and a swiveling lid mounted on an eccentrically positioned cylindrical roller, which transfers dynamic loads to the container, reducing stress on mechanical parts and incorporating a seal to protect against environmental particles, ensuring the device only affects vehicles exceeding speed limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a high-speed restricting device with moving parts is used to affect only speeding vehicles, then vehicles driven at legal speed are not disturbed, but the device is exposed to considerable strain from heavy trucks and industrial vehicles, making it short-lived and injury-prone
Solution Approach 1:
The patent replaces complex mechanical moving parts with a magnetic field-based system. A magnet is mounted on the vehicle, and when it passes over a sensor in the road, it triggers an electromagnetic actuator that raises a lid. This substitution eliminates wear and tear on mechanical components while maintaining the ability to selectively affect speeding vehicles.
Solution Approach 2:
The patent uses a pneumatic or hydraulic actuator system to raise and lower the lid. The actuator is controlled by a sensor that detects the presence of a magnet on approaching vehicles. This allows the lid to be raised only when needed, reducing exposure to strain from heavy vehicles while maintaining selective enforcement capability.
2Ease of operation
If a lid-raising mechanism is used to restrict high-speed vehicles, then speeding vehicles are affected, but the moving mechanics are subjected to considerable strain and proven short-lived
Solution Approach 1:
The patent replaces continuous mechanical moving parts with an electromagnetic actuator system that only activates when needed. The magnet-sensor-actuator mechanism eliminates constant mechanical wear, significantly extending the service life of the device while maintaining the speed regulation function.
Solution Approach 2:
The lid is raised periodically only when a speeding vehicle is detected, rather than remaining in a constant state of movement or being continuously strained. This periodic activation based on sensor detection reduces cumulative stress on the mechanical components.
3Reliability
If known high-speed restricting devices are exposed to weather, sand and gravel, then the devices suffer from environmental degradation, but encapsulation is difficult due to their mechanically extensive construction
Solution Approach 1:
By replacing extensive mechanical components with an electromagnetic actuator and sensor system, the patent simplifies the overall device construction. This simplified design is much easier to encapsulate and protect from environmental factors like weather, sand, and gravel, improving environmental resistance.
Solution Approach 2:
The patent extracts and removes complex mechanical transmission components from the system, replacing them with a simpler electromagnetic actuation system. This extraction of unnecessary mechanical complexity makes the device easier to protect from environmental degradation.

Function Achieved in This Case
The road module extends the lifespan of the device by minimizing mechanical stress and protecting it from environmental factors, while only impacting vehicles violating speed regulations, ensuring vehicles within limits are not disturbed.

AI summary
A road module for regulating a passability of vehicles on a roadway. The road module includes an elongated container immersed across the roadway and having an upper plane being essentially at level with the roadway. A lid is pivotally arranged and hinged along an edge of the container. The edge extends along a longitudinal side of the container facing vehicles approaching the road module. The lid forms at least a part of the upper plane of the container. An eccentrically mounted cylindrical roller is configured to support the lid at an opposite longitudinal side of the container. The roller is rotatable between an upper or a lower position. An actuator is configured to rotate the roller to lower and raise the lid, thereby forming a downward ramp in a passing direction of the vehicles when the roller is in the lower position.
