Solution Overview

Problem

Existing trekking and ski poles lack a reliable and efficient mechanism for a releasable connection between the grip and the user's hand or glove, which is crucial for maintaining control during use.

Innovation Solution

A connector assembly comprising a grip top with a locking channel and a release button, utilizing a magnetically attracted ferrous puck for secure attachment to the user's glove, allowing easy locking and unlocking with a spring-assisted mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional strap or tether connection is used between the pole and user's hand, then the connection is simple in structure, but the reliability and security of the connection is insufficient

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnector assembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connector assembly is divided into distinct functional components: a grip top portion with a locking channel, a release button mechanism, and a magnetic coupling system. This segmentation allows each component to perform its specific function reliably while maintaining overall system manageability despite increased complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The release button is nested within the grip top structure, with the magnetic element embedded in the release button and the ferrous element embedded in the puck. This nesting arrangement consolidates multiple functions into compact, integrated components, improving reliability without excessive complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a secure locking mechanism is implemented, then the connection reliability improves, but the ease of operation for quick release deteriorates

Engineering Contradiction:
Improvelocking reliabilityVSAvoidquick release ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The magnetic coupling system replaces traditional mechanical locking mechanisms. The magnetic attraction between the magnetic element in the release button and the ferrous element in the puck provides secure locking without complex mechanical interlocks, while allowing rapid release when the button is actuated.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The spring is pre-compressed in the locked position, storing energy ready for quick release. When the release button is actuated, the pre-compressed spring immediately drives the release mechanism, enabling rapid detachment without requiring the user to exert significant force or perform multiple actions.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a magnetic coupling system is used, then the ease of attachment improves, but the device complexity increases

Engineering Contradiction:
Improveattachment easeVSAvoidmagnetic system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The magnetic coupling functionality is extracted as discrete elements: a magnetic element embedded in the release button and a ferrous element embedded in the puck. This extraction allows the magnetic system to be integrated into the existing connector structure without requiring a complete redesign, balancing ease of attachment with manageable complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If the locking channel is designed with tight tolerances, then the manufacturing precision improves, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvelocking channel precisionVSAvoidmanufacturing difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The locking channel geometry is designed with specific dimensional parameters and tolerances that balance manufacturing feasibility with functional performance. The channel dimensions are optimized to accommodate the puck while maintaining secure locking, using parameter ranges that are achievable with standard manufacturing processes rather than requiring ultra-precise machining.

Inventive Principle:
Principle #35Parameter changes

AI summary

A trekking pole or the like includes a grip top (20) fixed at the top end. A user's glove (72) supports a puck (70). The puck (70) is placed on a release button (50) then slid into a locking channel (30) on the grip top (20), from the release button (50) into the locking channel (30). Thereafter, the release button (50) automatically locks the puck (70) in the channel (30). When the release button (50) is pressed down, the puck (70) can be removed. A magnet (62) on the release button (50) can assist in locating the puck (70) properly on the release button (50) and also in withdrawing the puck (70) from the locking channel (30).
