Rotating Sleeve Parking Stopper with Spring Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking blocks cause damage, breakage, and noise due to rolling friction when vehicles stop, and pose safety risks as they can lead to pedestrian accidents when not properly secured.
Innovation Solution
A shock-absorbing safety car stopper with a rotating sleeve and elliptical shaft hole, featuring a coil spring for elastic restoring force, which absorbs impact and prevents rotation when not in use, ensuring smooth operation and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed parking block is used to prevent tire passage, then parking guidance is effective, but it causes damage and breakage due to rolling friction when vehicles stop
Solution Approach 1:
The invention transforms the static parking block into a dynamic system where the touch bar can rotate around the shaft. The sleeve rotates during vehicle contact to reduce friction, and the brake mechanism dynamically locks the sleeve in position when not in use, resolving the contradiction between effectiveness and durability
2Manufacturing precision
If a fixed parking block is used to guide tire position, then parking accuracy is improved, but rolling friction causes noise and impact force to the vehicle
Solution Approach 1:
The sleeve acts as an intermediary between the tire and the touch bar. It rotates during contact to convert sliding friction into rolling friction, significantly reducing noise and impact force while maintaining parking position accuracy
3Ease of operation
If a rotating mechanism is added to reduce friction, then smooth operation is achieved, but the structure becomes more complex and may pose safety risks
Solution Approach 1:
The brake mechanism is designed to automatically lock the sleeve in its operational position through gravitational force and mechanical engagement, eliminating the need for additional control systems or complex actuation mechanisms
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 reduces damage and noise, extends the lifespan of components, minimizes tire wear, and prevents pedestrian accidents by smoothly returning the touch bar to its original position and securing it when not in use.
Implementation Method 1
a coil spring that is inserted into the shaft and applies elastic restoring force (or resilience) to the touch bar
Implementation Method 2
a brake that includes a shaft hole formed to be fitted with the shaft, is provided in a longitudinal direction between the touch bar and the base plate
