Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladders lack the ability to effectively monitor and respond to various operating conditions that affect user safety and stability, such as unlocked spreader bars, unstable footing, and user presence on prohibited steps, which can lead to hazardous situations.
Innovation Solution
Integration of sensors on a ladder to detect conditions like spreader bar position, foot placement, and user presence, coupled with a computing device for real-time monitoring and alert generation, enabling safety alerts and data logging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors and computing devices are integrated into the ladder, then safety monitoring capability is improved, but device complexity increases
Solution Approach 1:
The ladder is divided into modular sections with sensors distributed at specific locations (base, spreader bars, steps). Each sensor module is an independent unit that can be individually installed, replaced, or maintained without affecting the entire system, thus managing complexity through segmentation.
Solution Approach 2:
The computing device serves multiple functions: it processes data from various sensors, generates safety alerts, logs maintenance information, and provides user guidance. This multi-functionality consolidates what could be multiple separate systems into a single integrated unit, improving reliability while controlling complexity.
2Measurement precision
If multiple sensors are installed to detect various operating conditions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Different sensor types are strategically placed at specific locations where they can most effectively detect relevant conditions. For example, sensors are positioned at the base to detect footing stability, at spreader bars to detect unlocking, and on steps to detect user presence. This targeted approach maximizes measurement precision for each operating condition without requiring sensors throughout the entire ladder structure.

AI summary
A ladder including sensors is provided. A remote computing device is also provided that communicates with the sensors to facilitate detection of various operating conditions. Methods for detection are also provided. One aspect of the invention provides a method for detecting stability of a ladder, the ladder comprising a pair of side rails, a plurality of steps that extend between the side rails, a sensor coupled with the ladder and configured to detect loading on the ladder. The method includes: communicating wirelessly, by a remote computing device, with the sensor; detecting, by the remote computing device, a presence of a user on the ladder; during the presence of a user on the ladder, monitoring the sensor, by the remote computing device, for an instability condition; and when the instability condition occurs, generating an alert of the instability condition.
