Cross Bar Mount Interface for Tool-Free Base Plate Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in providing a quick and secure mounting system for cross bars to base plates in cargo areas, which are essential for supporting various types of cargo during transportation.
Innovation Solution
The proposed attachment structure includes a cross bar with adjustable and fixed mounts at each end, featuring cleats that can be selectively secured to base plates with mounting apertures. The adjustable mount includes an actuator and lock pin mechanism for easy locking and unlocking, while the fixed mount uses a clamp bar for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting systems are used to attach cross bars to base plates, then the connection is secure and reliable, but the mounting process is time-consuming and requires tools
Solution Approach 1:
The mounting system is divided into separate modular components: a base plate with mounting apertures, cross bars with mounts, and quick-release latches. Each component can be independently manufactured and assembled, allowing for tool-free quick attachment and detachment while maintaining secure connection during use.
Solution Approach 2:
The mounting system transitions from a static permanent connection to a dynamic reversible connection. The quick-release latches enable the cross bars to be quickly attached and detached, providing adaptability for different cargo configurations while maintaining structural integrity when mounted.
2Adaptability or versatility
If traditional permanent mounting systems are used, then the connection is stable and secure, but the system lacks flexibility for different cargo configurations
Solution Approach 1:
The base plate includes multiple mounting apertures arranged in different patterns and orientations, allowing the same base plate to accommodate various cross bar configurations for different cargo types. The universal mounting system can adapt to bikes, kayaks, storage boxes, and other cargo while maintaining secure attachment through standardized quick-release mechanisms.
3Adaptability or versatility
If adjustable mounts are provided for all cross bar positions, then the system is highly versatile, but the device complexity increases
Solution Approach 1:
The system implements adjustability selectively rather than universally. The base plate provides multiple fixed mounting positions with apertures arranged for common cargo configurations. The quick-release latches provide local adjustability at each mounting point, allowing users to select from pre-defined positions without requiring complex continuous adjustment mechanisms at every location.

AI summary
An attachment structure includes a cross bar body extending between a first end and a second end, a first mount coupled to the first end, and a second mount coupled to the second end. The first mount and the second mount each include at least one cleat that is selectively securable to a base plate that includes a plurality of mounting apertures.
