Hat-Mounted Earmuff With Elastic Clip and Collapsible Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earmuff designs for hats lack an efficient attachment mechanism and fail to provide a collapsible or folding frame, making them difficult to attach, remove, and carry conveniently while maintaining effectiveness and cost-effectiveness.
Innovation Solution
An earmuff design featuring an elastic attaching member with a holder assembly and cover assembly, including flexible rings and a soft material cover, allowing for easy attachment to a hat, adjustment, and retraction into a compact configuration, utilizing a magnetic or sewn attachment for secure clipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional earmuff designs are used without attachment members, then the earmuff structure remains simple, but the earmuff cannot be securely attached to a hat
Solution Approach 1:
The earmuff is divided into separate components: a hat attachment member (clip or magnet) and the earmuff body. This segmentation allows the attachment function to be added independently without redesigning the entire earmuff structure, resolving the contradiction between attachment security and structural simplicity.
Solution Approach 2:
The attachment member serves multiple functions: it attaches the earmuff to the hat, provides a mounting point for the ear cups, and enables easy removal and reattachment. This multi-functionality improves attachment reliability without proportionally increasing device complexity.
2Ease of operation
If a rigid frame structure is used for the earmuff, then the earmuff provides stable support, but the earmuff becomes difficult to carry and store
Solution Approach 1:
The earmuff frame incorporates flexible or collapsible elements that allow it to transition between a rigid supported state during use and a compact folded state for carrying. The dynamic structure maintains stability when needed while enabling portability, resolving the contradiction between frame strength and carrying ease.
Solution Approach 2:
The ear cups and frame components are designed to nest within each other when folded, creating a compact carrying configuration. This nesting approach maintains the structural integrity needed for support during use while dramatically reducing the carrying profile.
3Object-affected harmful factors
If thick rigid earmuff covers are used, then the ear protection effectiveness is improved, but the earmuff becomes bulkier and less comfortable
Solution Approach 1:
The earmuff covers use composite construction combining rigid outer shells for protection with soft interior linings (fur, fleece, or fabric) for comfort. This composite approach provides effective ear protection while maintaining comfort and reducing bulk, resolving the contradiction between protection effectiveness and ease of operation.
Solution Approach 2:
The earmuff covers employ thin but effective shielding materials that provide noise and cold protection without the bulk of traditional thick covers. The flexible shell design maintains protective functionality while improving comfort and portability.

AI summary
An earmuff for hats, including a holder assembly and a cover assembly. The holder assembly includes a first ring and a second ring coupled together from a bottom portion thereof defining a separated top portion. The cover assembly encloses the holder assembly. The cover assembly is attached to a hat through the holder assembly. The holder assembly is operated to open and close to be clipped to the hat. The cover assembly, when attached to the hat, is an earmuff.
