Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc locking devices suffer from deformation during high-torque braking, leading to unreliable locking and potential false braking due to eccentric rotation of the brake disc.
Innovation Solution
A disc locking device featuring a base with lateral slope surfaces forming a wedge-shaped groove, brake clamping blocks with friction plates, a support mechanism, a front baffle, and a brake trigger mechanism, along with a needle roller slide plate and limiting cover plate, which together provide stable and reliable braking by preventing deformation and eccentric rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a disc locking device with wedge-shaped structure is used for emergency braking, then braking performance is improved, but device deformation occurs during high-torque braking reducing reliability
Solution Approach 1:
The device is divided into multiple independent components: base, brake clamping blocks, support mechanism, front baffle, brake trigger mechanism, needle roller slide plate, and limiting cover plate. This segmentation allows each component to perform its specific function independently, preventing cumulative deformation and improving overall reliability during high-torque braking.
Solution Approach 2:
The support mechanism with elastic elements (springs) is installed beforehand to provide pre-compression and cushioning force on the brake clamping blocks. This beforehand cushioning prevents deformation by compensating for mechanical stresses before they occur during braking operations.
2Ease of operation
If the brake disc is allowed to rotate freely, then operational flexibility is improved, but false braking occurs due to eccentric rotation
Solution Approach 1:
The limiting cover plate is positioned to preemptively counteract eccentric rotation by providing a mechanical stop before the brake disc can rotate far enough to cause false braking. This preliminary anti-action maintains operational flexibility while preventing harmful eccentric movements.
Solution Approach 2:
The needle roller slide plate acts as an intermediary between the brake clamping blocks and the base, providing a low-friction sliding surface that allows controlled movement while maintaining positional accuracy, thus preventing false braking due to uncontrolled eccentric rotation.

AI summary
A disc locking device, comprising: a base (2), a brake clamping block (7), a support mechanism, a front baffle (3), a limiting cover plate (1), a needle roller slide plate (13) and a brake triggering mechanism (10), and so on. The base (2) includes a bottom plate (21) and two side vertical plates (22) which are integrally arranged on the bottom plate (21); the two side vertical plates (22) are oppositely arranged, and the inner walls thereof are all lateral slope surfaces, so that a wedge-shaped groove having a large front opening and a small rear opening is formed between the two laterally-vertical plates; and mounting holes penetratingly connected to the brake triggering mechanism (10) are formed on the side vertical plates (22). The support mechanism includes a front support mechanism and a rear support mechanism. Flexible movement and reliable braking of the brake clamping block and eccentric blocking of a brake disc are achieved, thus deformation of the device is eliminated, and erroneous braking caused by the eccentric rotation of the brake disc is avoided, thereby greatly improving the reliability of the device, meeting standard requirements, truly achieving productization and making it possible to apply and popularize the safety brake.
