Solution Overview

Problem

Conventional motocross boots provide inadequate flexibility and comfort due to rigid protection means on the shin and calf, which limit the boot's ability to fit various leg sizes and cause discomfort through pressure and folding issues during movement.

Innovation Solution

The boot features sliding elements within guiding pockets in the shin and calf protection means, allowing for increased flexibility and improved fit by accommodating different leg shapes through relative movement, while maintaining protection and comfort through padding and strategically designed plates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rigid protection means are provided on the shin and calf, then protection against impacts is improved, but flexibility and comfort of the boot are worsened

Engineering Contradiction:
Improveprotection against impactsVSAvoidflexibility and comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protection means are designed with sliding elements that allow dynamic movement relative to the boot leg-piece. The guiding means enable the protection means to move forward and backward along the leg during flexing movements, transforming the static rigid structure into a dynamic system that adapts to leg movements while maintaining protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The protection means are divided into separate functional elements: a front protection means for the shin and a rear protection means for the calf, each with its own sliding element and guiding means. This segmentation allows independent movement of each protection zone, improving overall flexibility while maintaining protection at each segment.

Inventive Principle:
Principle #1Segmentation

2Reliability

If rigid protection means are provided on the shin and calf, then protection against impacts is improved, but ability to fit various leg sizes is worsened

Engineering Contradiction:
Improveprotection against impactsVSAvoidability to fit various leg sizes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sliding elements within guiding means allow the protection means to dynamically adjust their position along the leg, enabling the boot to accommodate different calf sizes and leg shapes. The protection means can move to different positions to fit various leg profiles while maintaining adequate protection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The position of the protection means along the leg can be changed through the sliding mechanism, allowing adjustment of the fit for different leg sizes. The closing devices work in conjunction with the sliding elements to adjust the tightness and position, adapting the boot to various leg dimensions.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If rigid protection means are provided on the shin and calf, then protection against impacts is improved, but pressure and folding issues during movement are worsened

Engineering Contradiction:
Improveprotection against impactsVSAvoidpressure and folding issues
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The sliding elements allow the protection means to move dynamically during leg flexing, preventing the formation of excessive folds and reducing pressure points. The guiding means enable smooth movement that accommodates natural leg flexion without creating harmful folding patterns in the boot upper.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sliding elements act as intermediaries between the rigid protection means and the flexible boot upper. They allow relative movement that reduces the transmission of rigid constraints to the boot upper, minimizing folding and pressure issues while maintaining protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to a motorcycling boot 10, in particular a motocross boot. The boot 10 comprises a sole 40 and an upper 14 in turn comprising a bottom portion 15, suitable for surrounding the user's foot, and a leg-piece 16 suitable for surrounding the user's leg. A first protection means 20 is connected to said leg-piece 16 in the region of the shin, while a second protection means 30 is connected to said leg-piece 16 in the region of the calf. Said first protection means 20 comprises an element 24 suitable for sliding inside guiding means 25 formed in said first protection means 20, while said second protection means 30 comprises an element 34 suitable for sliding inside guiding means 35 formed in said second protection means. The movement of said elements 24, 34 allows variation, during use of the boot 10, of the configuration of the leg-piece 16.
