Headphone Rotary Bracket Assembly With Hidden Compact Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rotary connecting structures in headphones occupy large space, affect aesthetics, and cause damage during loading and unloading, leading to inconvenient assembly and disassembly.
Innovation Solution
A rotary bracket design comprising a first bracket, a second bracket, a fixing piece, and a rotary connecting piece, where the rotary connecting piece penetrates through a transfer interface and is positioned in a mounting cavity, allowing for an unfolded and folded state without direct connection through a rotating shaft, facilitating assembly and disassembly while hiding the structure for improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rotating shaft is used for rotary connection between headband and support arms, then the connection is stable and reliable, but the space occupancy increases and aesthetics are affected
Solution Approach 1:
The patent divides the rotary connection system into separate components: a rotating shaft embedded in the headband and a rotating seat on the support arm. This segmentation allows the connection function to be distributed, reducing the visible space required while maintaining stability through the engagement of these separate parts.
Solution Approach 2:
The rotating shaft is nested within the headband structure, and the rotating seat is integrated into the support arm. This nesting approach hides the rotary mechanism within the existing structural components, reducing external space occupancy while preserving the rotational function and connection reliability.
2Reliability
If the headband and support arms are tightly connected with the rotating shaft, then the connection is stable, but the appearance is damaged during loading and unloading
Solution Approach 1:
The patent separates the connection function into a rotating shaft (in headband) and rotating seat (on support arm), allowing the support arm to connect and disconnect without involving the headband's main structure. This prevents appearance damage to the headband during loading and unloading operations.
Solution Approach 2:
The rotating seat acts as an intermediary component between the support arm and the rotating shaft. It enables the support arm to engage and disengage from the headband system without directly manipulating the headband's appearance, thus preventing appearance damage while maintaining connection stability.
3Ease of operation
If a rotating shaft connection is used, then the rotary function is achieved, but the assembly and disassembly process is inconvenient
Solution Approach 1:
By segmenting the rotary connection into a rotating shaft and a rotating seat, the patent enables independent assembly and disassembly of the support arm from the headband. The rotating seat can be detached from the rotating shaft without affecting the headband structure, making assembly and disassembly more convenient while preserving the rotary function.
Solution Approach 2:
The patent implements a dynamic connection system where the support arm can rotate between connected and disconnected states. The rotating seat allows the support arm to be easily attached to and detached from the rotating shaft, providing operational flexibility and convenience for both assembly and disassembly processes.
