Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional stud installation methods are used, then studs can be installed on tires, but specialized tools are required which are cumbersome and expensive
Solution Approach 1:
The installation tool is segmented into a drill bit portion and a stud receiver portion that can be separated. The drill bit can be removed and replaced with a different drill bit if needed, while the stud receiver portion remains. This segmentation allows for flexibility and reduces the need for specialized complex tools.
Solution Approach 2:
The stud installation tool is designed to perform multiple functions: it can drill pilot holes, install studs, and remove studs. The tool accepts different drill bits and can accommodate various stud types, making it a universal tool that replaces multiple specialized tools.
2Productivity
If conventional stud installation methods are used, then studs can be installed on tires, but the process is time-consuming and requires specialized equipment
Solution Approach 1:
The stud receiver portion is pre-configured with the correct threading and geometry to match the stud. Pilot holes can be pre-drilled to the correct depth and diameter using the integrated drill bit, eliminating the need for multiple steps and specialized tools during the actual stud installation.
Solution Approach 2:
The drill bit and stud receiver are combined in a single tool assembly, allowing the user to drill and install the stud in one continuous operation without changing tools or equipment. This merging of functions significantly reduces installation time.
3Reliability
If studs are installed using pressure to displace rubber, then studs are retained in position, but removal is difficult and tools become ineffective due to material buildup
Solution Approach 1:
The stud receiver portion is designed with a dynamic gripping mechanism that can adapt to the stud geometry. The gripping surfaces can apply variable pressure to maintain a secure hold during removal, overcoming the resistance created by material buildup on the stud.
Solution Approach 2:
The stud receiver acts as an intermediary between the removal tool and the stud. It provides a clean interface that does not accumulate material, allowing for effective force transmission during removal without being affected by material buildup on the stud itself.
4Reliability
If tires are purchased with studs pre-installed, then traction is improved, but the consumer cannot control stud placement or number
Solution Approach 1:
The tool is designed to be user-friendly and does not require specialized knowledge or skills to operate. The consumer can easily drill pilot holes, install studs at desired locations, and adjust the number of studs based on their specific needs, enabling self-service customization of stud configuration.
Solution Approach 2:
The stud installation process is segmented into simple, independent steps that can be performed individually. The consumer can choose to install studs in specific patterns or locations by drilling pilot holes and installing studs one at a time, providing full control over stud placement and number.

AI summary
A removable tire stud of the present disclosure provides a stud and tool to remove the same. The removable tire stud includes a solid hexagonal shaped head portion having a top surface, the head portion being continuous with a shank portion. The shank portion including an unthreaded neck proximal to the head and a threaded portion with a blunt tip. The thread extends from the blunt tip to the unthreaded neck, and a first portion of the thread is sharpened to cut through rubber of a tire. A notched flange is fixed to the head portion proximal to the shank portion. The notched flange has two diametrically opposed notches in an outer edge thereof, and each notch is centered on a vertex of the hexagonal shaped head.
