Commercial Vehicle Bow Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-part end bow construction for commercial vehicles is cumbersome to handle and poses a risk of injury during loading and unloading, as the separate parts can detach and require manual alignment, often necessitating additional tools and posing safety hazards.
Innovation Solution
A bow construction with a coupling device featuring a coupling bar and receptacle, activated by a spring element and pull cable, which locks the parts together securely, allowing for easy engagement and disengagement without manual intervention, and is controlled by the opening and closing of the rear cover, ensuring safe and efficient lifting and lowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-part end bow construction is used to allow rear loading, then loading height utilization is improved, but the risk of part detachment and injury increases
Solution Approach 1:
The end bow is divided into a first bow and a second bow that can be independently positioned. The first bow remains in its original position while the second bow is raised to allow rear loading access, enabling full utilization of loading height while maintaining structural separation for safety
Solution Approach 2:
A coupling device with coupling bar and coupling receptacle acts as an intermediary mechanism between the first and second bows. This coupling device securely connects the two bow parts together, preventing detachment while allowing controlled engagement and disengagement through the activation device
2Ease of operation
If the second bow is raised for rear loading, then loading access is improved, but manual alignment and handling complexity increases
Solution Approach 1:
The coupling device incorporates an activation device that automatically locks the coupling bar into the coupling receptacle when the second bow is raised. This self-locking mechanism eliminates the need for manual alignment and securing operations, reducing handling complexity while maintaining ease of loading access
3Reliability
If a coupling device with activation mechanism is added, then security against detachment is improved, but device complexity increases
Solution Approach 1:
Instead of requiring active mechanisms to maintain coupling, the design uses a passive coupling bar and receptacle that naturally engage and lock together. The activation device simply needs to release the coupling rather than maintain it, simplifying the overall mechanism while ensuring security against detachment
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
