Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional helmet fastening elements, such as snap buttons, complicate the attachment and detachment of cheek pads, provide an unstable connection, and fail to effectively isolate noise within the helmet.

Innovation Solution

A helmet padding system featuring a coupling device with a sliding element and sliding guide, along with a secondary male-female coupling mechanism, ensures a secure and noise-reducing attachment to the helmet, using a ring element to prevent relative movement and enhance stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If snap buttons are used as fastening elements, then the cheek pads can be removably connected to the helmet, but the attachment and detachment operations become complicated and difficult

Engineering Contradiction:

Improveremovable connection capabilityVSAvoidattachment and detachment operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The coupling device is divided into two separate components: a coupling element with a stem and head that inserts into a coupling cavity. This segmentation allows the cheek pad to be attached by a simple insertion motion and detached by pulling, eliminating the complexity of snap button operations while maintaining removable connection capability

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using protruding snap buttons that require precise alignment and pressing motions, the invention inverts the approach by using an inserting element that slides into a cavity. The attachment is achieved by insertion rather than by pressing buttons together, fundamentally reversing the fastening mechanism to simplify user operation

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If multiple snap buttons are used on each insert, then the connection between insert and helmet is improved, but the fastening operation becomes particularly complex and awkward

Engineering Contradiction:

Improveconnection stabilityVSAvoidnumber of fastening buttons

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple separate snap button fastening elements are merged into a single integrated coupling device consisting of one coupling element and one coupling cavity. This single coupling mechanism provides sufficient connection stability while eliminating the complexity of coordinating multiple buttons, directly resolving the contradiction between reliability and device complexity

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If snap buttons are used for fastening, then the cheek pads can be attached to the helmet, but the connection becomes unstable during head movements and repeated use

Engineering Contradiction:

Improveremovable fasteningVSAvoidengagement stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The coupling element with its stem and head is nested within the coupling cavity, creating a secure enclosed connection. The head of the coupling element rests on a support surface within the cavity, providing stable engagement that resists dislodgement during head movements and repeated use, while still allowing easy removal when needed

Inventive Principle:

Principle #7Nested doll (Nesting)

4Adaptability or versatility

If conventional fastening elements are used, then the cheek pads can be connected to the helmet, but noise diffusion occurs and isolation from external environment is reduced

Engineering Contradiction:

Improvefastening functionalityVSAvoidnoise diffusion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The traditional snap button fastening mechanism that creates gaps and noise pathways is extracted and replaced with a smooth coupling element插入cavity system. This new mechanism provides continuous contact between the cheek pad and helmet interior, eliminating noise diffusion paths while maintaining fastening functionality

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The present disclosure relates to a helmet padding (100) which includes a cushioning body (101) and a component of a coupling device (10) for removably connecting the cushioning body (101) to a remaining helmet portion. The component of the coupling device comprises one of a sliding element (11) and a sliding guide (12). The sliding element comprises a head (23) and a stem (24), while the sliding guide (120 comprises a seat with at least one insertion terminal mouth (34) and a longitudinal opening (31) configured to allow passage of the stem (24) and insertion of the head (23) of the sliding element (11) itself via the insertion terminal mouth (34) and prevent the head (23) from coming out of the seat (23). The present disclosure also relates to a helmet (1000) comprising such a helmet padding (100) and a method for coupling a helmet padding (100) to a remaining helmet portion.
