Solution Overview
Problem
Paddle switches in vehicles experience vibration and associated noise issues due to mechanical transmission from the vehicle's surface, leading to unwanted rattling and discomfort during operation.
Innovation Solution
A paddle switch system with a vibration reduction mechanism, including a housing, a pivot member, a cover, and a cube bumper made of elastomeric material, which dampens vibrations and reduces noise by acting as a buffer between the paddle and the housing, providing preloading to the dome switch for stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a paddle switch is mounted in a vehicle steering wheel or dashboard, then it enables convenient control of electrical components, but it experiences vibration and noise from the vehicle's surface
Solution Approach 1:
The patent introduces a vibration reduction mechanism as an intermediary component between the paddle switch and the vehicle surface. This mechanism includes a vibration isolation structure that mediates the transmission of vibrations from the vehicle's steering wheel or dashboard to the paddle switch, thereby reducing the harmful effects while preserving the operational convenience of the control device.
Solution Approach 2:
The patent converts the harmful vibrations into a beneficial effect by using the vibration energy to pre-load the dome switch. The vibration reduction mechanism is designed to utilize the vibrational forces to maintain constant contact pressure on the dome switch, ensuring reliable electrical connection while simultaneously reducing the transmission of unwanted vibrations and noise to the switch components.
2Reliability
If the paddle is rigidly mounted to ensure stable operation, then it provides precise control, but it transmits more vibration and noise
Solution Approach 1:
The patent employs composite material structures in the vibration reduction mechanism, combining materials with different damping characteristics. The vibration isolation structure uses composite materials that provide both structural stability for reliable operation and vibration-damping properties to reduce noise transmission, thus achieving a balance between operational reliability and vibration reduction.
3Object-affected harmful factors
If a vibration reduction mechanism is added to dampen vibrations, then it reduces noise and improves comfort, but it increases device complexity
Solution Approach 1:
The patent segments the paddle switch assembly into distinct functional modules: the paddle switch unit, the vibration reduction mechanism, and the mounting structure. This segmentation allows the vibration reduction mechanism to be designed as a separate, modular component that can be independently optimized and installed, thereby reducing the overall complexity of the integrated system while achieving effective vibration and noise reduction.
