Solution Overview

Problem

Existing hearing protection devices face challenges in packaging efficiency due to the need for separate clips to maintain the compact configuration of elongated connectors, which occupy space and require additional steps, leading to larger packaging sizes and increased complexity.

Innovation Solution

A hearing protection device featuring a frangible attachment element in the elongated connector that temporarily connects its portions, allowing the connector to be compacted and packaged without external clips, and can be easily converted to an elongated configuration by breaking the attachment element, simplifying manufacturing and packaging processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If separate clips are used to maintain compact configuration of elongated connectors, then the connector can be kept compact during packaging, but packaging size increases and packaging complexity increases

Engineering Contradiction:
Improvecompact configuration stabilityVSAvoidpackaging size
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The attachment element is integrated directly into the elongated connector structure, merging the function of connecting portions with the connector itself. This eliminates the need for separate external clips, thereby reducing packaging size while maintaining the compact configuration stability during shipping and storage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The attachment element serves multiple functions: it connects portions of the elongated connector to maintain compact configuration, and it is built-in as part of the connector structure. This multi-functionality allows the same component to provide both structural integrity and compactness without requiring additional packaging materials.

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

2Stability of the object's composition

If separate clips are used to maintain compact configuration of elongated connectors, then the connector can be kept compact during packaging, but packaging process complexity increases

Engineering Contradiction:
Improvecompact configuration stabilityVSAvoidpackaging process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

By integrating the attachment element directly into the connector structure, the packaging process is simplified. The connector arrives pre-configured with its attachment elements, eliminating the need for separate steps to apply external clips during packaging, thereby reducing packaging process complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of stationary object

If the elongated connector is kept in compact configuration without attachment elements, then packaging size is reduced, but the connector cannot maintain compact configuration during storage and transport

Engineering Contradiction:
Improvepackaging sizeVSAvoidcompact configuration maintenance
Core Design Contradiction:
Volume of stationary objectVSStability of the object's composition

Solution Approach 1:

The elongated connector is divided into multiple portions that can be connected or disconnected. The attachment elements enable these segments to be joined together to form the complete connector, allowing the connector to be packaged in a compact segmented state while maintaining configuration stability when assembled.

Inventive Principle:
Principle #1Segmentation

AI summary

Various embodiments of a hearing protection device and a method of forming such device are disclosed. The hearing protection device includes a first hearing protector, a second hearing protector, and an elongated connector including a first end that is connected to the first hearing protector and a second end that is connected to the second hearing protector. The device further includes a frangible attachment element disposed between a first portion of the elongated connector and a second portion of the elongated connector that temporarily connects the first portion to the second portion such that the elongated connector is in a compact configuration. The elongated connector is adapted to be disposed in an elongated configuration when the frangible attachment element is broken.
