Elevator Brake Cushion Replacement via Detachable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator brake systems require disassembly for cushion replacement, which is time-consuming, costly, and poses safety risks due to high specialization requirements and potential reliability issues post-reassembly.
Innovation Solution
A detachably mounted cushion support system with receiving holes and threaded screws allows for easy replacement of cushions without disassembling the entire elevator brake, ensuring simplicity, safety, and reduced maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the whole elevator brake is disassembled for cushion replacement, then the cushion can be replaced, but the replacement becomes extremely time-consuming and heavy in workload
Solution Approach 1:
The brake assembly is divided into independent functional modules: the stationary plate assembly (with cushion support) and the movable plate assembly. The cushion support is further segmented as a separate detachable component from the stationary plate, allowing the cushion to be replaced by only disassembling the cushion support rather than the entire brake assembly. This segmentation enables localized maintenance while preserving the integrity of other brake components.
2Ease of repair
If the whole elevator brake is disassembled for cushion replacement, then the cushion can be replaced, but the workload becomes heavy and replacement costs increase
Solution Approach 1:
The brake assembly is divided into independent functional modules: the stationary plate assembly (with cushion support) and the movable plate assembly. The cushion support is further segmented as a separate detachable component from the stationary plate, allowing the cushion to be replaced by only disassembling the cushion support rather than the entire brake assembly. This segmentation enables localized maintenance while preserving the integrity of other brake components.
Solution Approach 2:
The cushion support is extracted as a独立的 detachable component from the stationary plate. It is mounted on the stationary plate via threaded holes and screws, allowing it to be easily removed and reinstalled. This extraction enables the cushion to be replaced by only removing the cushion support, significantly reducing the complexity of the replacement process compared to disassembling the entire brake assembly.
3Ease of repair
If the whole elevator brake is disassembled and reassembled for cushion replacement, then the cushion can be replaced, but running reliability may be hard to recover, causing safety risks
Solution Approach 1:
The brake assembly is divided into independent functional modules: the stationary plate assembly (with cushion support) and the movable plate assembly. The cushion support is further segmented as a separate detachable component from the stationary plate, allowing the cushion to be replaced by only disassembling the cushion support rather than the entire brake assembly. This segmentation enables localized maintenance while preserving the integrity of other brake components.
Solution Approach 2:
The cushion support is designed with specific local features (threaded holes and mounting surfaces) that enable secure attachment to the stationary plate. This localized design ensures that the cushion support can be reliably reinstalled after cushion replacement, maintaining the integrity of the brake system without requiring complete disassembly and reassembly, thereby preserving running reliability.

AI summary
The present invention provides an elevator brake and a cushion replacement method of the elevator brake, and relates to the field of elevator braking technologies. The elevator brake (10) includes a first block (110) and a second block (120) that collide with each other during braking, and a cushion (190) located between the first block (110) and the second block (120), and further includes a cushion support (130a, 130b) detachably mounted on the first block (110) or the second block (120), where the cushion (190) is disposed on the cushion support (130a, 130b). A cushion (190) of the elevator brake (10) can be replaced without disassembling the whole elevator brake.
