Steering Wheel Vibration Device Clip Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing steering wheel vibration devices are complex to assemble and mount due to the use of screws for fixing the circuit substrate, which complicates the connecting work and assembly process.
Innovation Solution
A steering wheel design that incorporates a vibration device with a vibration motor, a mounting bracket, a circuit substrate, and a clip, where the circuit substrate is connected to the motor body via terminal holes and the clip ensures secure attachment without screws, simplifying the assembly and mounting process by using a clip with a pressing section and retaining element to hold the circuit substrate in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used for mounting the circuit substrate on the motor body, then the circuit substrate is securely fixed, but the assembling process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the traditional mechanical screw-fixing system with a clip-based mechanical system. The clip has a pressing section that presses the circuit substrate against the motor body and a retaining element that engages with the motor body to prevent disengagement, eliminating the need for screws while maintaining secure fixation.
Solution Approach 2:
The fixing mechanism is divided into distinct functional components: the pressing section for applying pressure and the retaining element for preventing disengagement. This segmentation allows each component to perform its specific function efficiently, simplifying the overall assembly process compared to using a single screw mechanism.
2Reliability
If a screw is used to fix the circuit substrate, then the connection is reliable, but the wiring and mounting work becomes more complicated
Solution Approach 1:
The patent replaces the screw-based mechanical system with a clip-based system that integrates both fixation and support functions. The clip's pressing section and retaining element work together to securely hold the circuit substrate without requiring additional wiring or mounting steps, thereby simplifying the manufacturing process.
3Volume of moving object
If the vibration device is downsized with an integrated circuit substrate and connector, then the device size is reduced, but the assembly complexity increases without proper fixing means
Solution Approach 1:
The patent merges the circuit substrate and connector into a single integrated component that is directly connected to the vibration motor. This integration reduces the overall device size by eliminating separate mounting requirements and reduces assembly complexity by using the clip to secure the integrated unit as a single entity.
Solution Approach 2:
The patent replaces complex multi-step assembly procedures with a simple clip-based fixation system. The clip's design allows for quick attachment and detachment of the integrated circuit substrate and connector assembly, maintaining downsizing benefits while simplifying the assembly process.

AI summary
A steering wheel provided with a vibration device. The vibration device includes a vibration motor with a weight attached to a rotational axis protruding out of a motor body, a mounting bracket which mounts the motor on the steering wheel body, a circuit substrate which includes a connector for feeding the vibration motor with electricity and a terminal which is plugged in a terminal hole of a mounting base of the motor body such that the circuit substrate is connected to the motor body, and a clip which is assembled with the motor body and mounted on the mounting bracket together with the motor body. The clip includes a pressing section which presses the circuit substrate against the motor body and a retaining element that is engaged with and holds the mounting bracket so as to help the pressing section to keep pressing the circuit substrate toward the motor body.
