Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turntables with fixed detent profiles are limited in their functionality and cannot provide adequate haptic feedback for various operating tasks, as they are not adaptable to different functions and require complex structures and control systems.
Innovation Solution
A turntable with a variable detent profile featuring a magnetic ball locking device, where carriers with latching elements and locking contours can be configured differently to change the detent course, allowing for customizable haptic feedback by activating specific locking devices, enabling multiple locking positions and varying forces required to overcome latches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed locking profile is used in the turntable, then the structure is simple, but the adaptability for different functions is limited
Solution Approach 1:
The patent applies the dynamics principle by making the locking profile changeable through multiple carriers (2, 3, 4) with different locking contours that can be selectively locked. The permanent magnets in the ball locking devices can be moved between end positions to engage different carriers, allowing the turntable to dynamically switch between different detent profiles (first, second, third locking contours) depending on the required function, thus achieving adaptability without permanent structural complexity.
Solution Approach 2:
The patent implements universality by designing a single turntable structure that can perform multiple functions through different locking contours. The multiple carriers with different locking contour configurations allow the same basic structure to provide various detent profiles suitable for different operating tasks, making the turntable universally applicable across multiple functions rather than requiring separate specialized components for each function.
2Adaptability or versatility
If magnetorheological liquid is used to control viscosity for different latching curves, then variable detent profiles are achieved, but the structure becomes complex and expensive
Solution Approach 1:
The patent replaces the complex magnetorheological liquid system with a purely mechanical solution using multiple physical carriers with different locking contours. Instead of using magnetic fields to control liquid viscosity, the invention uses mechanical ball locking devices with permanent magnets that physically engage with different carriers to select different locking profiles, eliminating the need for complex fluid control systems while achieving the same variable detent profile functionality.
Solution Approach 2:
The patent applies segmentation by dividing the locking mechanism into multiple separate carriers (2, 3, 4), each with its own locking contour. This segmentation allows independent selection of different locking profiles by engaging specific carriers, replacing the monolithic magnetorheological liquid approach with discrete, selectable mechanical components that are simpler to control and manufacture.
3Adaptability or versatility
If multiple carriers with different locking contours are used, then adaptability for different functions is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple locking contours into a single integrated turntable structure with multiple carriers arranged around the same rotary shaft. Instead of using separate mechanisms for each locking profile, all carriers and locking contours are combined in one compact assembly, allowing variable detent profiles to be achieved without proportionally increasing overall device complexity or size.
