Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensors built into screws fail to effectively detect heat flow issues in mechanical organs, particularly near engines or areas with friction, due to weight and space constraints in vehicles, limiting their ability to monitor operating faults.
Innovation Solution
A fixing element, such as a screw, incorporating a sensing element that detects temperature differences between areas along a heat flow, utilizing thermocouples and a lightweight, high-strength material design to monitor heat flow within mechanical organs, allowing for early fault detection and minimizing installation challenges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sensors are built into screws for monitoring, then fault detection capability is provided, but weight and space constraints in vehicles are exceeded
Solution Approach 1:
The patent combines the fixing element (screw) and the sensing element into a single integrated unit. The sensor is built directly into the screw structure, merging two previously separate components (fixing mechanism and monitoring system) into one unified element, thereby eliminating the need for separate sensor housings and reducing overall system weight and space requirements
Solution Approach 2:
The fixing element is designed to perform multiple functions simultaneously: it provides mechanical fastening while also serving as a monitoring device for heat flow and fault detection. This multi-functionality allows the system to eliminate dedicated monitoring equipment, reducing weight and space while maintaining reliability
2Reliability
If dedicated monitoring systems are installed in vehicles, then operating fault detection is improved, but space and weight constraints are violated
Solution Approach 1:
The sensing element is nested within the fixing element structure. The sensor components are housed inside the screw body, utilizing the existing structural space of the fixing element rather than requiring separate dedicated spaces in the vehicle. This nesting approach allows monitoring functionality to be embedded without increasing overall system footprint
3Measurement precision
If sensors are positioned away from heat sources, then weight and space constraints are met, but heat flow detection accuracy is reduced
Solution Approach 1:
The sensing element is positioned locally at the specific location where heat flow measurement is most critical - directly within or adjacent to the mechanical organ being monitored. This localized positioning ensures high measurement precision for detecting heat flow anomalies while the integrated design keeps overall weight minimal
