Modular Skid Plate With Integrated Tow Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skid plates are heavy and rigid, making routine maintenance and repair complicated due to their location on the undercarriage of off-road vehicles, and they do not provide adequate utility for tasks like towing while protecting drive components from damage.
Innovation Solution
A lighter, modular skid plate design with a base region and orthogonal flanges that can be welded to both the tow frame member and vehicle frame member, featuring strategically placed lightening holes and an access port for oil drain, allowing for easier service and integration of a tow hook mount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rigid skid plates are used to protect powertrain components, then protection reliability is improved, but weight increases and maintenance complexity worsens
Solution Approach 1:
The skid plate is divided into a modular assembly comprising a skid plate, tow bar, and crossmember that can be independently manufactured and then assembled together. This segmentation allows each component to be optimized separately and facilitates easier installation and maintenance of the entire assembly.
Solution Approach 2:
The skid plate assembly integrates multiple functions into a single structure: the skid plate protects the powertrain, the tow bar provides towing capability, and the crossmember offers additional structural support and mounting points. This multi-functionality reduces the need for separate components, thereby reducing overall weight.
2Strength
If conventional fixed skid plates are welded to the frame, then structural integrity is improved, but ease of repair worsens
Solution Approach 1:
The skid plate is segmented into a modular assembly with the tow bar and crossmember that can be attached via welding or alternative means. This segmentation allows the assembly to be detached and replaced as a unit or in parts, significantly improving maintenance ease while maintaining structural integrity through proper joining methods.
Solution Approach 2:
The attachment method transitions from permanently fixed welding to a more dynamic system where the modular assembly can be detached, replaced, or reconfigured. This dynamic approach allows for easier repair and maintenance while still providing sufficient structural strength during operation.
3Duration of action of stationary object
If heavy rigid skid plates are used for protection, then durability is improved, but device complexity worsens
Solution Approach 1:
The skid plate system is segmented into standardized modular components (skid plate, tow bar, crossmember) that can be manufactured using consistent processes and assembled through repeatable procedures. This standardization reduces assembly complexity while maintaining durability through proven design and manufacturing methods.
Solution Approach 2:
The modular assembly provides multiple functions (protection, towing, structural support) through integrated components that work together as a unified system. This approach reduces overall device complexity by eliminating the need for separate protective plates, tow hooks, and reinforcement members that would otherwise be required.
4Reliability
If conventional skid plates are designed solely for protection, then protection function is improved, but adaptability worsens
Solution Approach 1:
The skid plate assembly is designed as a multi-functional unit where the skid plate provides protection, the integrated tow bar enables towing operations, and the crossmember offers additional mounting points for accessories. This universality allows the same assembly to serve multiple purposes, greatly improving adaptability while maintaining protection functionality.
Solution Approach 2:
The design extends the traditional two-dimensional skid plate into a three-dimensional modular assembly by adding the vertical tow bar and crossmember elements. This dimensional expansion enables additional functions (towing, accessory mounting) without compromising the primary protection function of the skid plate itself.
