Spectacles Headband with Pivot Brackets to Lift Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearing spectacles for long durations can be uncomfortable due to weight on the ears and nose, and they often slip forward, especially when the user is sweating, as existing designs do not effectively alleviate these issues.
Innovation Solution
A spectacles supporting headband with a head-gripping member and brackets that can move between inactive and active positions, lifting the spectacles off the ears and nose by rotating about a pivot point, using first and second projections to securely hold the arms in place, thereby preventing tilting and maintaining the spectacles on the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spectacles are worn with arms resting on ears and nose, then the spectacles can be held in position, but the weight causes discomfort and the spectacles slip forward during movement
Solution Approach 1:
A headband is introduced as an intermediary device between the user's head and the spectacles. The headband includes a head-gripping member that contacts the head and brackets with projections that contact the spectacle arms, creating a new support path that bypasses the ears and nose to bear the spectacles' weight.
Solution Approach 2:
The headband is divided into functionally distinct segments: a head-gripping member for anchoring to the head, brackets for contacting the spectacle arms, and projections for providing upward support force. This segmentation allows each component to be optimized for its specific function in distributing weight and preventing slippage.
2Reliability
If the headband is made resilient to grip the head, then it can maintain secure contact, but the structure becomes more complex
Solution Approach 1:
The head-gripping member is made from resilient material that can elastically deform to accommodate different head sizes and shapes. This parameter change in material properties allows the same simple loop structure to adapt to various users without requiring complex adjustment mechanisms.
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 headband significantly reduces the weight on the ears and nose, prevents slipping, and maintains the spectacles in a comfortable position, enhancing wearability by distributing the weight and securing the frames relative to the head.
Implementation Method 1
The head-gripping member may comprise an open loop of resilient material configured to fit snugly around a user's head in use. The resilient material may comprise metal, such as stainless steel. The term 'resilient' may mean that the loop is expandable by the exertion of force on its ends, but that after removal of the force, the loop returns to its previous size and shape.

AI summary
To reduce pressure of wearing spectacles on a wearer's ears and nose, a spectacles supporting headband (10) is provided, for use with spectacles having lenses, a bridge, and two arms (70) positionable over a wearer's ears (75). The spectacles supporting headband comprises a head-gripping member (20) and two brackets (30), each bracket comprising a first projection (40), the spectacles supporting headband configured to move between an inactive and active position, relative to a user's head, wherein, in the active position, each first projection is configured to support a respective arm (70) of the spectacles, such that the spectacles are lifted, and held, off the ears (75), and wherein each bracket also comprises a second projection (50) to grip the respective spectacles arm between it and the first projection, the projections being in fixed locations relative to the headband, to prevent the respective arm (70) tilting relative to the head-gripping member.
