Anti-vibration Actuator Mounting Device with Protrusion-Slider Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration systems for motor vehicles are prone to accidental fall due to single-point fixation, posing risks to pedestrians and material damage, and existing dual-screw solutions are bulky, difficult to install, and require unnecessary tools.
Innovation Solution
A mounting device with a slider and protrusion system that provides two secure attachment points on the vehicle body, allowing lateral sliding and tool-free installation, using a soft iron core, magnetic coil, and rubber spring for vibration maintenance, along with a non-return mechanism to prevent accidental disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single screw is used to fix the actuator, then the device complexity is reduced, but the reliability of mounting is insufficient and accidental fall risk increases
Solution Approach 1:
The mounting device is segmented into two distinct attachment mechanisms: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.
Solution Approach 2:
The slider acts as an intermediary element between the protrusion and the vehicle body wall. It provides a simple receptacle that receives the protrusion laterally and prevents disengagement, while requiring no tools for operation. The slider mediates the connection by converting a simple lateral insertion motion into a secure mechanical constraint.
2Reliability
If two screws are used to fix the actuator, then the reliability of mounting is improved, but the device complexity and size increase
Solution Approach 1:
The mounting system is divided into two attachment points: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.
Solution Approach 2:
The protrusion-slider mechanism replaces the need for a second screw and screwdriver. Instead of using a threaded mechanical fastener requiring rotational motion and tools, the design uses a lateral insertion motion where the protrusion simply slides into the slider receptacle. This substitution eliminates the complexity of a second screw-fastening system while maintaining dual-point attachment reliability.
3Reliability
If two screws with large center distance are used, then the reliability is improved, but the ease of operation deteriorates due to tool accessibility issues
Solution Approach 1:
The protrusion-slider mechanism replaces the need for a second screw and screwdriver. Instead of using a threaded mechanical fastener requiring rotational motion and tools, the design uses a lateral insertion motion where the protrusion simply slides into the slider receptacle. This substitution eliminates the complexity of a second screw-fastening system while maintaining dual-point attachment reliability.
Solution Approach 2:
The protrusion is self-guiding and self-locking within the slider. Once the protrusion is laterally inserted into the slider receptacle, the geometry of the fit automatically prevents reverse motion and secures the actuator. This self-service mechanism eliminates the need for tools, adjustment, or complex alignment procedures during installation.
4Device complexity
If a compact mounting device is used, then the device complexity is reduced, but the reliability of preventing accidental fall decreases
Solution Approach 1:
The mounting system is divided into two attachment points: a screw connection for primary fixation and a protrusion-slider mechanism for secondary anchoring. This segmentation allows each component to perform its specific function independently, achieving reliable dual-point fixation without requiring a complex integrated system. The actuator body is divided into a soft iron core and a protrusion extension, enabling separate attachment methods.
Solution Approach 2:
The slider is integrated directly into the vehicle body wall structure, merging the mounting function with the existing body architecture. The protrusion is integrated as an extension of the actuator's soft iron core, combining the magnetic core function with the mechanical attachment function. This merging achieves reliable dual-point fixation without adding separate, complex mounting hardware.
