Solution Overview

Problem

Existing stud installation and removal methods are cumbersome, expensive, and often require specialized tools, with tools becoming ineffective due to material build-up, limiting user control over stud placement and removal on tires and footwear.

Innovation Solution

A stud with a hexagonal head and notched flange connected to a threaded shank, paired with a stud installation and removal device featuring an elongated shaft and wrench head with diametrically opposed walls and tips, allowing for easy installation and removal using a drill, and accommodating debris escape.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional stud installation methods are used with pressure forcing studs into holes, then studs are retained in position, but specialized cumbersome and expensive tools are required

Engineering Contradiction:
Improvestud retentionVSAvoidtool complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The stud is segmented into distinct functional parts: a hexagonal head portion for tool engagement, a notched flange portion for material buildup accommodation, and a threaded shank portion for secure retention. This segmentation allows each part to perform its specific function effectively while enabling simple tool design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stud design with hexagonal head and notched flange serves multiple functions: the hexagonal head enables both installation and removal with simple tools, the notched flange accommodates material buildup to maintain tool effectiveness, and the threaded shank provides secure retention. This multi-functionality eliminates the need for specialized tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If studs are pre-installed on tires, then traction is improved, but consumer control over stud placement and number is lost

Engineering Contradiction:
Improvetire tractionVSAvoiduser control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The stud design enables dynamic configuration where users can install and remove studs as needed. The simple hexagonal head design allows for easy installation and removal with basic tools, giving users control over stud placement and number while maintaining secure retention when installed.

Inventive Principle:
Principle #15Dynamics

3Ease of repair

If studs are removed and replaced by tire retailers, then stud replacement is possible, but material buildup on studs renders removal tools ineffective

Engineering Contradiction:
Improvestud replacementVSAvoidtool effectiveness
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The notched flange portion provides a specific local feature that addresses material buildup. The notches are strategically positioned to receive and accommodate material buildup, ensuring that the hexagonal head remains accessible to removal tools even after extended use, maintaining tool effectiveness throughout the stud's service life.

Inventive Principle:
Principle #3Local quality

4Ease of operation

If simple stud designs are used, then installation is easier, but material buildup on studs prevents tool effectiveness

Engineering Contradiction:
Improveinstallation easeVSAvoidtool effectiveness over time
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The notched flange portion provides a specific local feature that addresses material buildup. The notches are strategically positioned to receive and accommodate material buildup, ensuring that the hexagonal head remains accessible to removal tools even after extended use, maintaining tool effectiveness throughout the stud's service life.

Inventive Principle:
Principle #3Local quality
