Folding Headband Frame With Pivot Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Headbands for headphones typically occupy significant storage space due to their large size and limited adjustability, making them inconvenient to carry when not in use.
Innovation Solution
An arc-shaped headband frame with multiple pivotally connected joint structures that can be folded, incorporating a spring clip and plastic parts integrally injection-molded for enhanced stability and adjustability, allowing the headband to reduce its volume when not in use and maintain a secure fit when worn.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the headband is designed with a fixed rigid structure to ensure stability and secure fit, then the reliability is improved, but the volume when stored increases and portability deteriorates
Solution Approach 1:
The headband incorporates a folding mechanism with pivot axles that allow the frame to dynamically transition between an unfolded state (providing stability and secure fit) and a folded state (reducing storage volume). The joint structures enable controlled movement while maintaining structural integrity in both configurations.
Solution Approach 2:
The headband frame is divided into multiple segments connected by joint structures with pivot axles. This segmentation allows each segment to rotate relative to others, enabling the frame to fold into a compact configuration for storage while maintaining the necessary span and stability when unfolded for use.
2Adaptability or versatility
If the headband is made adjustable to improve comfort and fit for different users, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The folding mechanism with rotating joint structures provides adjustability by allowing the headband to be folded to different degrees, creating various compactness levels for storage while maintaining the necessary adjustments for different head sizes and preferences.
Applied Scientific Principles
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 folding mechanism significantly reduces storage space requirements while ensuring a secure and stable connection to the head, enhancing portability and reliability.
Implementation Method 1
the spring clip has a certain degree of elasticity, and when the headband is worn on the head, the elasticity of the spring clip ensures that the headband maintains a good clamping force

AI summary
This application discloses a headband and headphones, and the headband includes an integrally arc-shaped frame. The frame comprises: multiple joint structures arranged along the extension direction of the frame; multiple pivot axles, where two adjacent joint structures are rotatably connected by at least one pivot axle. In an example, an axial direction of the pivot axle is parallel to the axial direction of the frame, allowing the two adjacent joint structures to rotate relative to each other around the axis of the pivot axle, and enabling the frame to switch between a folded state and an unfolded state. The multiple joint structures include at least one joint structure (e.g., a first joint structure), which includes a plastic part and a spring clip that are integrally injection-molded together. The example headband can reduce storage space and increase portability, while enhancing the stability and reliability of the headband.
