Seat Depth Adjuster Locking Slider Noise Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat depth adjusters often produce rattling and grinding noises due to unnecessary play between components, which affects user experience and handling.
Innovation Solution
A seat depth adjuster with a base plate and support plate that includes a locking slider with a tooth structure, an energy storage device such as a rubber buffer or spring, and a rail system to eliminate play and noise, while maintaining easy handling and manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking slider is pressed into the toothed base plate using an energy storage device, then play and noise are eliminated, but the device complexity increases
Solution Approach 1:
The locking slider is integrated with the slider in a unified component design, eliminating the need for separate locking and sliding mechanisms. This merging reduces overall device complexity while maintaining the noise elimination function through the energy storage device that presses the locking slider into the toothed base plate.
Solution Approach 2:
The energy storage device automatically maintains pressing force on the locking slider against the toothed base plate, eliminating the need for additional active control mechanisms. The system self-regulates to eliminate play and noise without requiring external intervention or complex control systems.
2Ease of operation
If the support plate is made displaceable relative to the base plate for ease of adjustment, then ease of operation improves, but unnecessary play and noise are generated
Solution Approach 1:
The support plate is designed to be dynamically adjustable during operation but statically locked during use. The locking slider engages with the toothed base plate to create a stable, noise-free locked position while allowing easy displacement when the locking mechanism is actuated, thus combining ease of operation with noise elimination.
3Ease of operation
If manual operation of the handle is required to overcome the blocking force, then ease of operation is maintained, but the force required increases
Solution Approach 1:
The energy storage device applies a continuous partial force to press the locking slider into the toothed base plate, eliminating play and noise during normal operation. When adjustment is needed, the user applies excessive force through the handle to temporarily overcome this blocking force, allowing the locking slider to disengage from the toothed section. This approach maintains noise-free operation during use while enabling manual adjustment when required.
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 solution effectively reduces noise and play between components, ensuring smooth operation and enhanced user experience by using an energy storage device to press the locking slider into the base plate teeth, preventing rattling and squeaking.
Implementation Method 1
the energy storage device can, for example, be provided in the form of a rubber buffer
Implementation Method 2
The locking slider incorporates the energy storage device, which, in its operating position, presses the locking slider into the toothed base plate
Implementation Method 3
The slider has a slider spring. This slider spring ensures that the handle always returns to its starting position after manual operation
