Solution Overview

Problem

Existing studding tools and units are cumbersome to mount and dismount, leading to increased downtime and costs due to wear and tear, and lack flexibility in adjusting stud orientations.

Innovation Solution

A studding tool with a locking portion and a studding unit featuring a quick-connection mechanism, allowing easy attachment and detachment, and enabling adjustable stud orientations through a circumferential groove and positioning recesses, facilitated by a spring-loaded locking pin system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional mounting and dismounting mechanisms are used for studding tools, then the structural integrity and reliability are maintained, but the downtime increases and operational efficiency decreases due to cumbersome tool changes

Engineering Contradiction:
Improveoperational efficiencyVSAvoiddowntime
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The studding tool is divided into separable components with standardized interfaces. The tool body, stud magazine, and mounting interface are segmented to allow independent replacement and quick reconfiguration, enabling rapid tool changes without affecting other components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting mechanism transitions from static fixed connections to dynamic quick-connect interfaces. The tool can be rapidly mounted and dismounted through movable locking mechanisms that maintain structural integrity during operation but allow swift changes when needed.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If fixed studding tool configurations are used, then manufacturing precision and reliability are maintained, but adaptability decreases when different stud orientations are needed

Engineering Contradiction:
Improveflexibility in adjusting stud orientationsVSAvoidstud placement precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The studding tool is designed with universal mounting interfaces and adjustable positioning mechanisms that can accommodate multiple stud orientations and configurations. The same tool body can be adapted for different applications through interchangeable components and adjustable fixtures.

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

Solution Approach 2:

The tool configuration transitions from fixed to adjustable through dynamic positioning mechanisms. Angles and orientations can be changed during operation while maintaining precise stud placement through controlled adjustment mechanisms and standardized reference surfaces.

Inventive Principle:
Principle #15Dynamics

3Loss of time

If rapid quick-connection mechanisms are implemented for tool changes, then downtime is reduced and productivity increases, but device complexity increases due to additional locking and positioning components

Engineering Contradiction:
ImprovedowntimeVSAvoidcomplexity of quick-connection mechanism
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The quick-connection mechanism is segmented into modular components: mounting interfaces, locking elements, and positioning features are separated into distinct standardized parts. This modularity simplifies each individual component while enabling rapid assembly through their coordinated interaction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking mechanism incorporates self-latching features that automatically secure the tool to the studding unit without requiring manual intervention for the final locking action. The positioning recesses and locking portions work together to automatically align and secure the tool, reducing operational complexity.

Inventive Principle:
Principle #25Self-service

AI summary

A studding tool (10), studding unit (1) and a studding assembly for driving antiskid studs into stud holes of a tread of a tire in a first axial direction (X), is disclosed. The studding tool (10) as well as the studding unit (1) are arranged for quick connection/release of the studding tool (10) to/from an adapter (20) of the studding unit (1). This, by that the adapter (20) is fixed to the studding unit (1) and the adapter (20) comprises a first locking pin (22), which is arranged to engage with a locking portion (17) of the studding tool (10). Further, the studding tool (10) comprises a least one positioning recess (18a, 18b, …, 18n), which are arranged to engage with a second locking pin (26) of the adapter (20), for rotational lock of the studding tool (10) in the locked position relative the adapter (20).
