Modular Sensor Carrier Assembly for Road Machine Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road construction machines face high installation effort and reliability issues with ultrasonic sensors due to theft concerns and complex linkage systems, such as the Big Sonic-Ski, which require significant assembly and disassembly efforts.
Innovation Solution
A measuring system with a carrier having connectable portions, utilizing plug and socket connections with rotational hooks and conical shapes, and optionally wireless data/energy transmission, to securely and efficiently attach sensor heads for non-contact measurement, reducing assembly effort and enhancing reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a common linkage system (Big Sonic-Ski) is used to attach multiple sensor heads, then measurement coverage is improved, but installation effort and device complexity increase significantly
Solution Approach 1:
The carrier is divided into multiple connectable portions that can be attached separately to the construction machine. Each portion can be independently installed and removed, simplifying the overall installation process while maintaining comprehensive measurement coverage through modular expansion.
2Reliability
If sensor heads are permanently mounted on the construction machine, then measurement reliability is improved, but theft risk and installation flexibility are reduced
Solution Approach 1:
The connecting elements are pre-configured with hooks and electrical connections that enable quick attachment and detachment. This preliminary preparation allows the sensor system to be securely installed when needed for reliable measurement while enabling easy removal for theft prevention and transport.
3Reliability
If complex electrical connections are used for sensor attachment, then electrical reliability is improved, but assembly time and operational complexity increase
Solution Approach 1:
The mechanical connection (hook) and electrical connection are merged into a single integrated connecting element. When the portions are mechanically coupled through the hook, the electrical contacts are simultaneously connected, achieving both mechanical strength and electrical reliability in one assembly action without separate wiring steps.
