Hard Hat Clip With Segmented Slots And Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips for securing straps to hard hats often lack durability and ease of installation, leading to potential detachment and inconvenience in securing accessories like headlamps.
Innovation Solution
A clip design featuring a body with longitudinally extending fingers and slots for strap reception, combined with a hook portion for removably coupling to the hard hat, enhancing durability and ease of installation by using a resilient material and a thickness gradient for improved rigidity and snap-on functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing clips are used to secure straps to hard hats, then the attachment function is provided, but the durability is insufficient and detachment may occur
Solution Approach 1:
The patent changes the physical parameters of the clip by using a resilient material with specific elasticity properties and implementing a thickness gradient (thicker at the body, thinner at the hook portion). This allows the hook to deform elastically during snap-on installation and maintain strong holding force, resolving the contradiction between ease of installation and attachment reliability.
Solution Approach 2:
The patent employs a resilient material that combines elasticity with structural integrity. The material properties are engineered to provide both flexibility for easy installation and sufficient strength for durable attachment, preventing detachment while maintaining ease of installation.
2Ease of operation
If existing clips are used to secure straps, then attachment is provided, but ease of installation is poor
Solution Approach 1:
The clip is pre-formed with a thickness gradient during manufacturing, with the hook portion designed to be thinner and more flexible than the body. This preliminary preparation enables the hook to naturally deform and snap into place during installation without requiring additional tools or steps, significantly improving ease of installation and reducing installation time.
Solution Approach 2:
By varying the thickness parameter along the length of the clip (thicker body, thinner hook), the patent creates optimal mechanical properties for snap-on installation. The thinner hook portion requires less force to deform and install, while the thicker body provides structural support, resolving the contradiction between ease of installation and overall clip strength.
3Reliability
If straps are secured using conventional methods, then attachment is achieved, but strap bunching occurs
Solution Approach 1:
The patent divides the strap passage into multiple separate slots instead of a single opening. This segmentation distributes the strap evenly across multiple pathways, preventing bunching and ensuring neat, organized arrangement while maintaining secure attachment through the combined effect of multiple fingers and slots.

AI summary
A clip for a hard hat includes a body having a first end and a second end opposite the first end, a plurality of longitudinally extending fingers formed in the body, and a plurality of slots formed in the body to separate the plurality of longitudinally extending fingers. The plurality of slots is in communication with openings at the second end of the body. The plurality of slots is configured to receive a strap. The clip further includes a hook portion formed in the body at the second end of the body for removably coupling the clip to the hard hat. The hook portion curves toward the first end of the body.
