Adjustable Foot Sensor Mounting for Variable Floor Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foot sensors on sanitary ware are fixed in position and cannot adjust to varying floor levels, leading to inaccurate detection due to direct reflection from the floor or excessive distance, causing continuous actuator triggering or failure to trigger.
Innovation Solution
An adjustable mounting structure for foot sensors using an adapter sleeve and snap ring mechanism that allows for height adjustment and secure fixation, enabling precise positioning of the sensor relative to the floor level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the foot sensor is mounted at a fixed position, then the installation is simple and fast, but the detection accuracy deteriorates when the finished floor level does not match the sensor position
Solution Approach 1:
The patent implements an adjustable mounting structure that allows the foot sensor to be positioned at different heights along the vertical axis. The sensor can be moved between multiple predetermined positions or continuously adjusted, transforming the fixed mounting into a dynamic, adaptable configuration. This enables the sensor to be optimally positioned relative to the finished floor level, maintaining detection accuracy while preserving installation simplicity through the use of an adjustment mechanism.
2Length of stationary object
If the foot sensor is mounted too high, then the mounting position is higher relative to the floor, but the laser blind area increases and detection reliability deteriorates
Solution Approach 1:
The patent allows adjustment of the mounting height parameter to optimize detection performance. By changing the vertical position parameter of the foot sensor, the system can adapt to different finished floor levels and avoid the laser blind area problem. The adjustment mechanism enables precise control of the mounting height, ensuring the sensor is positioned at the optimal distance from the floor for reliable detection.
3Length of stationary object
If the foot sensor is mounted too low, then the sensor position is lower relative to the floor, but direct reflection from the floor causes continuous triggering and detection accuracy deteriorates
Solution Approach 1:
The patent enables adjustment of the mounting height parameter to eliminate direct floor reflection interference. By raising the sensor to an appropriate height, the laser beam clears the finished floor level and avoids receiving direct reflections that would cause false continuous triggering. The adjustment mechanism provides the necessary flexibility to position the sensor at the correct height for accurate foot detection.
4Measurement precision
If the foot sensor position is adjusted to accommodate different floor levels, then detection accuracy improves, but the device complexity increases due to additional adjustment structures
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism that allows the foot sensor to be repositioned vertically. This could involve an adjustable mount with multiple height positions, a telescopic structure, or a movable bracket system. The adjustment mechanism adds some complexity but maintains ease of installation through modular design, enabling the sensor to adapt to different finished floor levels while preserving operational simplicity.
Solution Approach 2:
The mounting structure is divided into separable components that can be independently adjusted and assembled. The adjustment mechanism is segmented into discrete elements (such as adjustable brackets, positionable mounts, or modular sections) that can be configured for different heights. This segmentation allows for flexible adaptation to various floor levels while keeping each component relatively simple in design.
