Parallel Fastening for Motorcycle Slider Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports footwear protection elements for motorcycling often fail to provide adequate protection when the slider becomes worn, as the fastening screws can penetrate the foot during impacts and become difficult to replace, leading to reduced safety and potential injury.
Innovation Solution
The design features a protection element with fastening means that are protected from impacts and abrasions, and are oriented parallel to the foot's surface, ensuring they do not pose a risk during falls or impacts, and can be easily replaced by inserting a fastening element into seats on both the base and slider that are aligned parallel to the foot's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixing screws are arranged perpendicular to the slider surface, then the connection between base and slider is stable, but the screw heads can penetrate the foot during impacts and become difficult to replace when worn
Solution Approach 1:
The patent inverts the traditional perpendicular screw arrangement by positioning the fastening means parallel to the outer surface of the slider. This inversion prevents screw heads from penetrating the foot during impacts while maintaining secure connection through the parallel orientation that distributes forces differently across the slider-base interface.
Solution Approach 2:
The patent transitions from a one-dimensional perpendicular fastening approach to a two-dimensional parallel arrangement. By positioning fastening means in the plane of the slider surface rather than perpendicular to it, the design eliminates the penetration hazard while preserving connection integrity through distributed fastening points across the surface area.
2Strength
If fixing screws are arranged perpendicular to the slider surface, then the connection is strong, but replacement becomes difficult when screw heads are damaged
Solution Approach 1:
By inverting the screw orientation from perpendicular to parallel with the slider surface, the patent enables easier access and manipulation of fastening means during replacement. The parallel arrangement allows tools to approach the fasteners from the outer surface without navigating around protruding screw heads, significantly improving repairability.
Solution Approach 2:
The patent applies different functional qualities to different parts of the fastening system. The parallel-oriented fastening means are positioned to be accessible from the outer surface for easy manipulation during replacement, while still providing sufficient connection strength through their geometric arrangement and engagement with the base structure.
3Object-affected harmful factors
If press-on engaging means are used instead of screws, then screw penetration risk is eliminated, but the connection between base and slider becomes unstable
Solution Approach 1:
The patent merges the advantages of both screw and press-on systems by using parallel-oriented fastening means that can be accessed from the outer surface. This hybrid approach eliminates the penetration risk of perpendicular screws while maintaining stable connection through the geometric arrangement and engagement mechanism, avoiding the instability problems of pure press-on systems.
Solution Approach 2:
The fastening system is designed to be dynamically adjustable, allowing the rider to tighten or loosen the parallel-oriented fastening means as needed. This dynamic capability enables secure connection during riding while facilitating easy removal and replacement when the slider becomes worn, adapting to different operational requirements.

AI summary
Sports footwear comprising an upper having a toe portion and a sole fixed to said upper. The sports footwear also comprises a protection element mounted on the side surface of the toe portion. This protection element is fixed permanently to the side surface of the toe portion and is provided with an outer surface provided with first coupling means for coupling a covering component on the protection element. The first coupling means of the protection element define a seat suitable for housing a fastening element for fastening the covering element onto the protection element. The seat has a direction of insertion which is substantially parallel to the side surface of the toe portion of the footwear on which the protection element is mounted. A covering component suitable for use with footwear is also described.
