Stabilizer Leg Proximity Control to Prevent Accidental Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stabilizer leg control systems for vehicles with heavy equipment, such as loader cranes, require tedious verification steps to prevent accidental movement of stabilizer legs, which can compromise safety and disrupt workflow.
Innovation Solution
A stabilizer leg control system that includes a user interface unit with a receiver unit and transmission units mounted near each stabilizer leg. The system activates transmission units only when the user interface unit is in proximity to the stabilizer leg, ensuring safe operation by requiring the user to be nearby and eliminating distracting verification steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If verification steps are added to prevent accidental stabilizer leg movement, then safety is improved, but workflow efficiency deteriorates
Solution Approach 1:
The patent replaces manual verification procedures with an automated optical recognition system. The control unit automatically detects and verifies the operator's identity and authorization status through optical signals (QR codes, barcodes, or biometric data) captured by a camera or scanner, eliminating the need for manual verification steps while maintaining safety requirements.
Solution Approach 2:
The patent introduces an intermediary verification system that acts as a mediator between the operator and the stabilizer leg control. The system uses optical recognition technology to automatically verify operator identity and authorization, providing a seamless verification process that does not interrupt workflow while ensuring safety protocols are met.
2Reliability
If manual verification steps are required before stabilizer leg operation, then safety is improved, but operation complexity increases
Solution Approach 1:
The patent replaces complex manual verification procedures with an automated optical recognition system. The control unit automatically captures optical signals (QR codes, barcodes, or biometric data), processes them through algorithms, and verifies operator authorization without requiring the operator to manually input data or follow complex verification steps.
Solution Approach 2:
The system enables self-service verification where the operator simply presents their identification (through optical code or biometric feature) and the system automatically completes the verification process. The control unit autonomously handles signal capture, processing, and authorization validation without requiring operator intervention in the verification steps.
