Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the motor and ratchet unit are attached to the housing separately, then each component can be independently manufactured and assembled, but the attachment accuracy between components deteriorates and assembly efficiency decreases
Solution Approach 1:
The motor and rotation stop mechanism are integrated onto a single motor bracket, forming a unified assembly unit. This merging of components ensures precise relative positioning between the motor and rotation stop mechanism while simplifying the assembly process, as the integrated unit is attached to the housing as one piece, thereby improving both attachment accuracy and assembly efficiency.
2Manufacturing precision
If the motor and rotation stop mechanism are positioned without integration, then design flexibility is maintained, but positioning accuracy between components deteriorates
Solution Approach 1:
The motor bracket serves as a common mounting platform that integrates both the motor and rotation stop mechanism. This merging approach ensures precise positioning accuracy between the motor shaft and rotation stop mechanism by defining their relative positions through the bracket's structure, while the bracket itself remains a simple, easily manufacturable component.

AI summary
An electric braking device includes a transmission mechanism that transmits rotation of a motor shaft member in an electric motor. The electric braking device includes an actuator section that applies a braking force to a wheel by pressing a friction member against a rotary body. The actuator section moves the friction member in response to rotation of the electric motor transmitted by the transmission mechanism. The electric braking device includes a rotation stop mechanism that stops rotation in a direction of reducing the braking force among rotational directions of the electric motor. The electric braking device includes a motor bracket 81 as a member to which the electric motor is attached. The rotation stop mechanism is further attached to the motor bracket.
