Sliding Registration Plate Holder for Rear Wheel Splash Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor-vehicle registration plate holders fail to effectively prevent water and debris from the rear wheel from wetting and dirtying the rider or passenger, especially in wet conditions.
Innovation Solution
A registration plate holder design featuring two flat bodies that slide perpendicular to each other, allowing the second flat body to extend and increase the holder's length, preventing water from reaching the rider or passenger, with optional reflective elements for improved visibility and adjustable stop means for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the registration plate holder is made compact with a single flat body, then the device complexity and manufacturing cost are reduced, but the ability to prevent water and debris from reaching the rider or passenger is insufficient
Solution Approach 1:
The registration plate holder is divided into two separate flat bodies (first flat body for holding the registration plate and second flat body for water protection) that can function independently yet work together as an integrated system, allowing each component to be optimized for its specific function while maintaining overall simplicity
Solution Approach 2:
The second flat body is designed to be slidable relative to the first flat body, allowing it to nest within or extend from the first flat body structure. This nesting arrangement enables the water protection function to be integrated into the existing holder structure without significantly increasing overall device complexity or space requirements
2Object-affected harmful factors
If the registration plate holder is made compact and fixed, then the manufacturing cost is reduced, but the adaptability to adjust water protection extension is lost
Solution Approach 1:
The second flat body is designed with sliding capability relative to the first flat body, transforming the static holder structure into a dynamic system that can adjust its water protection extension. This sliding mechanism allows users to customize the protection level according to different riding conditions while maintaining a simple mechanical structure without complex actuators or controls

AI summary
An embodiment of the invention discloses a motor vehicle (200) comprising a registration plate holder (10) comprising a first flat body (11) having two opposite larger faces, a first face (110) of which can support a vehicle registration plate (211) and a second face (111) of which can be applied to a structural element (210) of the motor-vehicle (200), and a second flat body (13) having two opposite larger faces (130, 131) arranged parallel to the larger faces of the first flat body, which is coupled to the first flat body (11) such as to be able to slide with respect to the first flat body (11), in a perpendicular direction to the thickness thereof, between a retracted position, in which most of the second flat body (13) is superimposed on the first flat body (11), and an extracted position, in which most of the second flat body (13) projects with respect to the first flat body (11), wherein the registration plate holder (10) is aligned with the rear wheel (205) of the motor vehicle (200), and is applied to the structural element (210) in such a way that the extraction movement of the second flat body (13) is carried out from a top in a downwards direction.
