Sliding Console Lever Mechanism for Easy Unlocking and Lock Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device that allows users to easily lock or unlock a sliding console in vehicles, which is essential for efficient use of interior space, especially with the development of autonomous driving systems.
Innovation Solution
A lever device for a sliding console is introduced, which includes a housing fastened to the cover of the sliding console, a knob for pressing, an operation rod that slides with the knob's operation, and a power transmission unit that rotates to slide the operation rod, thereby operating the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding console is fastened to a moving rail with locking mechanism, then the console can be fixed in position, but the locking mechanism requires complex operation to unlock
Solution Approach 1:
Instead of requiring the user to manually manipulate a complex locking mechanism to unlock, the invention inverts the approach by using a simple pressing action on a knob that automatically triggers the unlocking sequence through the power transmission unit, transforming a complex manual operation into a simple automatic activation
Solution Approach 2:
The power transmission unit acts as an intermediary between the simple pressing action on the knob and the complex locking mechanism. It translates the linear pressing motion into rotational motion that operates the locking mechanism, serving as a mediator that simplifies the user's interaction while maintaining the reliability of the locking system
2Ease of operation
If a knob is added to the cover for easy operation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The invention merges multiple functions into the compact power transmission unit housed within the housing: the knob pressing mechanism, the linear-to-rotational motion conversion, and the connection to the locking mechanism are all integrated into a single compact assembly that attaches to the console cover, minimizing overall structural complexity while maintaining ease of operation
3Adaptability or versatility
If the console is made movable for autonomous driving, then the adaptability is improved, but the risk of accidental unlocking increases
Solution Approach 1:
The housing structure and power transmission unit are designed to require a deliberate pressing action on the knob to activate unlocking. The mechanical design ensures that normal vibrations or accidental forces during autonomous driving operations cannot trigger the unlocking mechanism, providing preliminary protection against harmful accidental unlocking before it can occur
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The lever device enhances user convenience by allowing easy release of the sliding console's locking mechanism through a simple press of a knob, while also preventing accidental unlocking during sudden vehicle stops or collisions, thus ensuring safety.
Implementation Method 1
an elastic member inserted into the guide bar to be disposed between the knob body and the housing and configured to apply an elastic force to the knob body
Implementation Method 2
a pinion gear part rotatably fastened to the housing and engaged with the rack gear part
Implementation Method 3
a power transmission unit rotatably fastened to the housing and configured to rotate in correspondence with an operation of the knob to slide the operation rod
Implementation Method 4
a rack gear part protruding from the knob body and having gear teeth in a same direction as a movement direction of the knob body
