Gas Compression Spring Sensor Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas pressure springs equipped with sensors for monitoring physical variables cannot be inserted into standardized recesses of tools or machines without modifying the tools or machines, as existing sensor arrangements enlarge the cylindrical housing's external dimensions.
Innovation Solution
The sensor and electronics are integrated within the cylindrical housing's external dimensions, specifically arranged in the base part, allowing the gas pressure spring to maintain standard dimensions and enabling flexible use in existing recesses, with options for energy supply and data transmission that do not increase the housing's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor is added to monitor physical variables inside the gas pressure spring, then safety monitoring capability is improved, but the external dimensions of the housing are enlarged, making it incompatible with standardized recesses
Solution Approach 1:
The sensor and electronics are nested within the existing cylindrical housing, specifically utilizing the base part's internal space. This allows the monitoring system to be contained within the original external dimensions, maintaining compatibility with standardized recesses while adding safety monitoring functionality.
Solution Approach 2:
Instead of adding the sensor externally which would increase radial dimensions, the sensor is positioned in the base part along the longitudinal axis. This dimensional repositioning allows the sensor to monitor the gas compression chamber from within the existing footprint, avoiding enlargement of the housing's external dimensions.
2Extent of automation
If electronics are integrated within the gas pressure spring, then evaluation of detected values can be performed internally, but the device complexity increases
Solution Approach 1:
The sensor and electronics are merged into a single integrated unit positioned in the base part. This combination allows the gas pressure spring to autonomously detect and evaluate physical variables internally, reducing the need for external monitoring systems while maintaining manageable complexity through functional integration.
