Pivotable Shell Bearing Block for Adjustable Driver Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restraint systems for industrial truck drivers are not universally adaptable to different cabin shapes, leading to potential inefficiencies in protection and ease of use due to fixed pivot axes and lack of adjustability.
Innovation Solution
A restraint system with a bearing block having pivotable shells and a locking bolt allows for adjustable orientation of the protective bar, combined with a spring mechanism for ergonomic operation and a stop bolt for limited pivoting range, ensuring stability and ease of use across various cabin designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pivot axis is used for the protective bar, then the restraint system structure is simple, but the system cannot be adapted to different cabin shapes
Solution Approach 1:
The bearing block shells are made pivotable relative to each other about the pivot axis, allowing the protective bar orientation to be dynamically adjusted. This dynamic configuration enables adaptation to different cabin shapes while maintaining a relatively simple overall structure, as the adjustment mechanism uses the existing pivot axis rather than requiring additional complex mounting structures.
2Adaptability or versatility
If the protective bar is made adjustable to fit different cabins, then adaptability improves, but the device complexity increases
Solution Approach 1:
The locking bolt serves dual functions: it locks the adjustable element in position and simultaneously acts as the lock for the protective bar. This merging of functions reduces the number of separate components needed, achieving adjustability without proportionally increasing device complexity.
Solution Approach 2:
The locking bolt is designed to perform multiple functions: securing the adjustable element, locking the protective bar in position, and defining the pivoting range. This multi-functionality allows the restraint system to adapt to different configurations while using a minimal set of components.
3Stability of the object's composition
If the pivot axis is placed close to the cabin pillar, then stability improves, but the overall length of the restraint system decreases
Solution Approach 1:
The bearing block uses two shells that pivot relative to each other about a horizontal axis, adding a dimensional aspect to the adjustment mechanism. This allows the protective bar to be oriented correctly for different cabins without requiring a long mounting structure, achieving both compactness and stability.
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 system provides enhanced stability and adaptability to different cabin shapes, ensuring effective protection of the driver while simplifying the adjustment and operation of the protective bar, thereby improving safety and usability.
Implementation Method 1
it is more favorable if at least one spring acts between the protective bar and the bearing block. This spring automatically presses the protective bar into the release position.

AI summary
The system has bearing bracket (4) on which a protective bracket (10) is supported, and is pivoted between cab driver in the holding position and release position about an horizontal pivot axis (8). The bearing bracket has pivotable shells (7,9) among which first shell is connected with the vehicle (1) and a second shell is connected with the protective bracket to adapt relative to the cabin (2) in the jerk halt position.
