Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional braking apparatuses fail to accurately detect whether the brake is released or locked, leading to potential damage due to frictional heat or axis drop, as they cannot reliably identify faults such as brake coil breaks, cable breaks, or relay fusions, which cause the brake to remain stuck in a released or locked state.
Innovation Solution
A braking apparatus with a voltage detection unit and an observing unit that recognizes voltage variation patterns to determine the actuated and released states of the brake, allowing for the localization of fault sites and preventing damage by identifying breaks in wiring or relay fusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional braking apparatuses apply voltage to release the brake, then the brake can be released under normal conditions, but they cannot detect faults such as brake coil breaks, cable breaks, or relay fusions that prevent proper brake release or actuation
Solution Approach 1:
The braking apparatus monitors its own operational state by detecting voltage variations across the brake coil terminals. The system uses its existing voltage application mechanism to simultaneously perform braking control and fault detection, eliminating the need for separate external monitoring equipment. The control unit analyzes voltage patterns during voltage application and release phases to identify faults in brake coils, cables, and relays.
Solution Approach 2:
The system implements feedback by continuously monitoring voltage variations across the brake coil and comparing them against expected patterns. The control unit receives voltage information from the voltage detection unit, processes this feedback to determine brake state and detect anomalies, and adjusts operations based on detected fault conditions. This closed-loop monitoring enables reliable fault detection without adding significant system complexity.
2Object-affected harmful factors
If no fault detection system is implemented, then the device complexity remains low, but the brake may remain stuck in released or locked state causing damage to tools or workpieces

3Measurement precision
If voltage is applied to release the brake, then the brake releases under normal conditions, but faults like cable breaks or relay fusions prevent detection of actual brake state
Solution Approach 1:
The system implements feedback by continuously monitoring voltage variations across the brake coil and comparing them against expected patterns. The control unit receives voltage information from the voltage detection unit, processes this feedback to determine brake state and detect anomalies, and adjusts operations based on detected fault conditions. This closed-loop monitoring enables reliable fault detection without adding significant system complexity.
Solution Approach 2:
The system detects brake state and faults by monitoring changes in voltage parameters across the brake coil terminals. Instead of directly measuring mechanical brake position, the system infers brake state from electrical parameter variations (voltage magnitude, presence/absence of voltage) that occur during normal braking operations. This indirect measurement approach simplifies detection while maintaining precision.
