Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door trapping detection systems in sliding door opening and closing devices are affected by temperature and humidity changes, leading to inconsistent detection of door trapping, requiring manual position adjustments of all sliding doors, which is time-consuming.
Innovation Solution
A sliding door position adjustment assisting device and system that includes a drive control unit, measurement value acquisition unit, and measurement value output unit, allowing for remote determination of necessary position adjustments by simulating door end rubber contact with an opposing object and measuring load or moving distance, reducing the need for manual operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual position adjustment work is performed by operators checking each sliding door, then door trapping detection accuracy is improved, but adjustment time and labor cost increase
Solution Approach 1:
The sliding door opening and closing device performs self-diagnosis by automatically measuring the door end rubber contact force and determining whether position adjustment is needed, eliminating the need for manual operator intervention and reducing adjustment time while maintaining detection accuracy
Solution Approach 2:
The patent replaces manual mechanical inspection with an automated measurement system that uses sensors and control units to objectively measure door end rubber contact force, providing precise determination of adjustment necessity without human labor
2Reliability
If door end rubber hardness changes due to temperature and humidity, then door trapping detection reliability deteriorates, but position adjustment is required
Solution Approach 1:
The patent monitors changes in door end rubber physical properties (hardness) caused by temperature and humidity variations, and uses these parameter changes to determine when position adjustment is necessary, allowing the system to adapt to environmental conditions and maintain detection reliability
Solution Approach 2:
The control unit receives feedback from measurement units about door end rubber contact force and environmental conditions, processes this information to determine adjustment necessity, and triggers appropriate actions, creating a closed-loop system that maintains reliability despite rubber hardness variability
3Measurement precision
If all sliding doors are manually checked for position adjustment, then detection function accuracy is improved, but operational efficiency decreases
Solution Approach 1:
The patent extracts the essential measurement function from manual inspection by equipping each sliding door with independent measurement and control units that autonomously determine adjustment necessity, allowing parallel processing across multiple doors and significantly improving operational efficiency while maintaining detection accuracy
