Tire-Mounted Functional Component Base with Interlocking Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing functional component mounting bases face durability issues due to concentrated deformation at the interface between the rubber bottom plate and the metal securing mechanism when subjected to impact forces from bumps, leading to a decline in durability under high-speed conditions and impact forces.
Innovation Solution
A functional component mounting base with a rubber material and a fitting recess featuring raised and recessed portions that disperse inertia forces and absorb impact forces through elastic deformation, reducing the burden on the base and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a functional component securing mechanism with high rigidity (frame body and insertion piece) is used to withstand inertia forces, then high-speed durability is improved, but impact forces cause concentrated deformation at the interface between the rubber bottom plate and the securing mechanism, reducing overall durability
Solution Approach 1:
The patent removes the rigid frame body and insertion piece securing mechanism from the mounting base structure. Instead, it relies on the rubber material's inherent elasticity and the adhesive bonding between the rubber bottom plate and the tire inner surface to secure and protect the functional component, thereby eliminating the interface deformation problem caused by rigidity differences.
Solution Approach 2:
The patent changes the rigidity parameter of the mounting base by using a rubber material with appropriate elastic properties. This allows the base to deform elastically under impact forces rather than transmitting concentrated stresses to a rigid securing mechanism interface, thus improving durability under both high-speed and impact conditions.
2Reliability
If the opening diameter of the fitting recess is made smaller than the maximum diameter of the functional component-side attaching portion to ensure secure fitting, then the functional component is firmly held, but the functional component cannot be removed or replaced
Solution Approach 1:
The patent employs a two-stage fitting mechanism: initially, the opening diameter of the fitting recess is larger than the maximum diameter of the attaching portion, allowing easy insertion and removal of the functional component. After insertion, the rubber material deforms elastically under compression to create a secure holding force, achieving both ease of replacement and secure fitting through dynamic material response rather than fixed geometric constraints.
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
The solution provides a highly durable mounting base capable of withstanding inertia and impact forces, preventing the functional component from falling off and maintaining structural integrity during high-speed operations and bump encounters.
Implementation Method 1
the deformation of the rubber bottom plate may be confined by the functional component securing mechanism, and distortion tends to be concentrated to the interface, which becomes a rigidity difference, between the frame body of the functional component securing mechanism and the rubber bottom plate

AI summary
In order to provide a functional component mounting base having high durability to an inertial force acting on a functional component when a tire engages with and disengages from the road surface and to an impact force acting on the functional component mounting base when the tire passes over bumps the functional component mounting base (1) is formed of a rubber material, is attached to an inner surface (70) of the tire to mount the functional component (29) on the inner surface (70) of the tire, and characterized by being provided with a fitting recess (2) into which a functional component-side attaching portion (30) provided on the functional component (29) is fitted. The fitting recess (2) is formed such that an opening diameter of an opening (3) to the fitting recess is smaller than a maximum diameter of the functional component-side attaching portion (30), an inner surface (inner peripheral surface (9)) of the fitting recess (2) is formed as a fitting surface that fits with an outer surface (outer peripheral surface (31)) of the functional component-side attaching portion and a bottom of the fitting recess (2) is formed as raised and recessed portions (semicircular projections (5, 6) and a partition recess (8)) which fit with recessed and raised portions (semicircular recesses (34, 35) and a partition projection 33) formed on the functional component-side attaching portion (30).
