Retractable Headset Band Structure with Waveform Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headset head band structures lack a retractable and adjustable mechanism, limiting user comfort and fit due to an immovable elastic piece that restricts the head band's ability to adjust effectively.
Innovation Solution
A head band structure incorporating a retractable adjusting block with a sliding slice, elastic piece, and waveform locking portions that allow for telescopic adjustment, enabling the head band to be both retracted and extended, ensuring a secure and comfortable fit by decomposing pushing force into friction and positive forces for better contact and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the elastic piece is fastened immovably between the head band and the retractable part, then the structure is simple and stable, but the head band cannot be adjusted or retracted
Solution Approach 1:
The elastic piece is transformed from a fixed component to a movable one through the sliding groove mechanism. The retractable part can slide within the cover along the sliding groove, enabling the head band to dynamically adjust its length while maintaining structural simplicity
Solution Approach 2:
The head band structure is divided into separate functional components: the cover, the retractable part, and the elastic piece. This segmentation allows each component to perform its specific function independently while working together to achieve the overall adjustable functionality
2Ease of operation
If the elastic piece is made movable through a sliding mechanism, then the head band becomes retractable and adjustable, but the structure becomes more complex with additional components
Solution Approach 1:
The sliding mechanism is designed to be self-operating through simple linear motion. The retractable part slides within the cover along the sliding groove without requiring complex fastening or release mechanisms, making the adjustment operation intuitive and easy to perform
Solution Approach 2:
The length parameter of the head band is made variable through the sliding mechanism. By changing the position of the retractable part along the sliding groove, the effective length of the head band can be continuously adjusted to suit different user needs

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a retractable and adjustable head band structure that enhances user comfort by providing a better touching feeling and adjustable scope, ensuring the head band can be adjusted to fit various users effectively.
Implementation Method 1
an elastic piece (14). The substantial middle of the elastic piece (14) is arched upward to form a convex surface (141)
Implementation Method 2
A surface of each end cover (22) facing one sliding groove (211) has a waveform locking portion (221), and at least one stopping frame (222) disposed at one end of the waveform locking portion (221). The convex surface (141) keeps contacting with the waveform locking portion (221)
