Offset Mounting Element for Independent Torque Load Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for military vehicles face challenges when attaching external loads, as the increased tightening torque from the external loads can exceed the safe limits for protective elements, particularly those that are hollow or partially hollow.
Innovation Solution
A mounting device design that allows external loads to be mounted independently of the protective element, with a mounting surface offset in the axial direction. This design ensures that the tightening torque of the external load only acts on the mounting surface and not on the protective element, maintaining the protective element's torque within safe limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external load is pressed against the protective element via a nut that can also be screwed onto the mounting element, then the external load can be mounted on the vehicle, but the tightening torque acting on the protective element increases excessively
Solution Approach 1:
The mounting element is segmented into two independent screw connections: a first screw connection for mounting the protective element and a second screw connection for mounting the external load. This segmentation allows the tightening torques to be independently controlled, resolving the contradiction by enabling external load mounting without excessively increasing the torque on the protective element.
Solution Approach 2:
The two screw connections are arranged in different axial positions along the mounting element, creating spatial separation. The first screw connection is positioned at a first axial position while the second screw connection is positioned at a second axial position offset from the first. This dimensional arrangement in the axial direction allows independent torque application without interference.
2Weight of moving object
If the protective element is hollow or at least partially hollow, then the protective element can be designed with reduced weight, but the tightening torque must not exceed low limit values
Solution Approach 1:
The mounting element is divided into separate screw connections that independently control the tightening torque on the protective element versus the external load. This allows the protective element to be mounted with a low tightening torque appropriate for its hollow construction, while the external load can be securely fastened with higher torque through the second screw connection.
Solution Approach 2:
Different tightening torque characteristics are applied locally at different positions along the mounting element. The first screw connection applies a low tightening torque suitable for the hollow protective element, while the second screw connection applies a higher tightening torque for the external load, with the axial offset ensuring these local quality differences do not interfere with each other.
3Device complexity
If a single mounting element is used for both protective element and external load, then the device complexity is reduced, but the tightening torques become interdependent
Solution Approach 1:
A single mounting element is segmented to provide two independent screw connections with different axial positions. This maintains the simplicity of using one mounting element while achieving functional independence of the tightening torques through the spatial segmentation of the connection points along the axial direction.
Solution Approach 2:
The mounting element serves multiple functions simultaneously: it provides both the first screw connection for the protective element and the second screw connection for the external load. This multi-functionality reduces device complexity while the axial offset between connections ensures the tightening torques remain independent, allowing the single element to adapt to different mounting requirements.

AI summary
A mounting device for mounting a protective element, in particular on a vehicle, with a mounting element extending along a mounting axis, wherein the protective element can be mounted in a mounting plane via a screw connection with a defined tightening torque. The mounting element has a mounting surface which is arranged offset outwards in the axial direction relative to the mounting plane and on which an external load can be mounted via a second screw connection with a second tightening torque in such a way that the first and second tightening torques are independent of one another.
