Spring-Suspended Driver Stand Platform for Industrial Trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial truck driver stands experience instability and lateral swinging when traveling on uneven ground due to excessive spring excursion, making them unsafe and uncomfortable, especially when frequently mounted and dismounted.
Innovation Solution
A spring-suspended driver stand with an L-shaped platform featuring a horizontally arranged floor element and vertically standing wall element, utilizing a swing arm and guide roller for linear movement, combined with a spring and damping element to stabilize the platform and prevent tipping, and incorporating a position sensor for safety monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring-suspended stand platform is used to decouple the platform from the vehicle, then comfort is improved, but lateral swinging and tilting occur causing instability
Solution Approach 1:
A guide element acts as an intermediary between the guide roller and the vehicle frame, constraining the swing arm's movement to a linear path. This mediator prevents lateral swinging while preserving the spring suspension's comfort benefits by allowing vertical movement only.
Solution Approach 2:
The invention changes the movement parameter from rotational/swinging motion to linear translational motion through the guide element. This parameter change eliminates lateral tilting while maintaining the spring's ability to provide comfort through vertical displacement.
2Stability of the object's composition
If the standing surfaces are made very wide to prevent lateral swinging, then stability is improved, but the platform becomes top-heavy and unsafe
Solution Approach 1:
The guide element serves as a mediator that provides lateral stability without requiring a wider platform. It constrains the swing arm's movement path, preventing lateral swinging while maintaining a compact, safe platform width.
3Stability of the object's composition
If a guide roller is provided rolling on a guide element, then linear movement is achieved, but device complexity increases
Solution Approach 1:
The guiding function is segmented from the spring suspension system into a separate guide element and guide roller mechanism. This segmentation allows each component to perform its specific function independently, achieving linear movement control without significantly increasing overall system complexity.
4Adaptability or versatility
If the stand platform is frequently mounted and dismounted, then adaptability is improved, but excessive spring excursion is felt unsafe
Solution Approach 1:
The guide element acts as a safety intermediary that limits spring excursion by constraining the swing arm to linear movement. This prevents excessive movement during frequent mounting/dismounting operations while maintaining the adaptability of the spring suspension system.
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 provides a stable and comfortable driver stand by minimizing lateral tipping and ensuring safe operation through controlled linear movement and damping, even under uneven conditions and one-sided loads, while the position sensor enhances safety by detecting the presence of the driver.
Implementation Method 1
The floor element is spring-suspended by means of at least one spring element and a swing arm relative to a frame of the drive part
Implementation Method 2
Consequently, spring elements according to the invention are also to be understood as a spring and/or damping element
