Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conversion of a parking device for a three-point construction machine between parking and non-parking positions is laborious and inefficient.
Innovation Solution
The implementation of resilient elements, such as tension springs, and a belt-like tension element that generates torque to pivot and secure parking supports, combined with foot actuation for easy position adjustment, simplifies the locking mechanism by allowing parking supports to be easily rotated and locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional parking device locking mechanism is used, then the parking supports can be locked in position, but the conversion between parking and non-parking positions is laborious and inefficient
Solution Approach 1:
The parking support is designed with a dynamic locking mechanism that allows easy transition between locked and unlocked states. The resilient element (spring) provides automatic return motion, enabling the parking support to be quickly moved between parking and non-parking positions without manual repositioning of the entire support structure.
Solution Approach 2:
The resilient element (spring) automatically returns the parking support to its default position after activation. The locking element engages and disengages automatically when the parking support is moved, eliminating the need for manual locking operations and reducing the time required for position conversion.
2Device complexity
If a simple parking support arrangement is used, then the device complexity is reduced, but the locking reliability may be compromised
Solution Approach 1:
The parking support system is divided into distinct functional components: the parking support structure, the resilient element (spring), the locking element, and the tension element. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity. The locking element can be easily replaced or adjusted without affecting the entire system.
Solution Approach 2:
The resilient element (spring) acts as an intermediary between the parking support and the locking mechanism. It provides the necessary force to engage the locking element reliably while allowing easy release. The tension element serves as another intermediary that generates torque to rotate the parking support into the correct position for locking, ensuring reliable engagement without complex mechanisms.
3Force
If the tension element is arranged close to the locking element, then the device complexity is reduced, but the torque generation capability is insufficient
Solution Approach 1:
The tension element is arranged at a distance from the locking element, creating a larger moment arm for torque generation. This spatial arrangement in another dimension allows the tension element to generate sufficient torque to rotate the parking support into the locked position without requiring a more complex mechanical advantage system.

AI summary
The device has a joint axle running in a travel direction and arranged at a frame (1) of a distribution machine by a joint arrangement. The axle is provided between a parking position and a non-parking position of pivotable parking supports (3). The supports are locked in the position by a locking element. A tension spring (17) is assigned to the supports for fixing and/or locking the supports in the positions, and holds the supports in each position. The locking element is arranged at distance to the spring. A foot actuating element at the supports adjusts the supports in the positions.
