Light-Shielding Eye Mask With Adjustable Strap for Side-Sleep Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye masks suffer from loose fixing straps that easily slip, causing eye irritation, and tight straps that compress nerves, affecting blood circulation and comfort, while also having uncomfortable designs that cause a foreign body sensation when sleeping on the side.
Innovation Solution
An improved light-shielding eye mask with an adjustable fixing strap, a detachable eye contact layer made of Lycra fabric with elastic sponge filling, and vertical I-shaped periocular contact edges, featuring an adjustment buckle for stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fixing strap is made tight to prevent slipping, then the stability of the eye mask is improved, but it compresses the nerves around the eyeballs and affects blood circulation
Solution Approach 1:
The fixing strap is designed with elastic material and an adjustable buckle mechanism, allowing it to be flexible rather than rigid. This enables the strap to provide necessary stability while accommodating the contours of the head and avoiding excessive compression on nerves and blood vessels.
Solution Approach 2:
The fixing strap incorporates an adjustment buckle that allows dynamic adjustment of tightness according to different users and situations. This dynamic adjustment capability enables the strap to maintain optimal stability without causing harmful compression, resolving the contradiction between stability and comfort.
2Ease of operation
If the fixing strap is made loose to improve comfort, then the comfort of wearing is improved, but it easily slips during sleep causing eyes to be irritated by light
Solution Approach 1:
The adjustment buckle enables dynamic adjustment of the strap tightness, allowing users to find the optimal balance between comfort and fixing reliability. The elastic material further enhances this dynamic adaptation, maintaining both comfort and reliability during sleep.
Solution Approach 2:
The elastic material changes its physical parameters (tension, flexibility) based on the wearing conditions, automatically adapting to provide appropriate tightness. This parameter change capability allows the strap to maintain reliability while preserving comfort throughout the sleep period.
3Illumination intensity
If the eye mask is designed to contact the entire eyes for light shielding, then the light-shielding effect is improved, but it causes a sense of pressure on the entire eyes
Solution Approach 1:
The eye contact layer is designed with differentiated local qualities: the central eye-contacting area uses soft, thin material for comfort, while the peripheral light-shielding areas provide adequate coverage. This local differentiation maintains light-shielding effectiveness while reducing overall eye pressure.
Solution Approach 2:
The eye contact layer uses flexible, thin material that conforms to the eye contours without creating excessive pressure. This flexible film approach provides adequate light shielding while maintaining comfort and avoiding harmful compression on the eyes.
4Strength
If the side parts near the temple are designed thick for structure, then the structural integrity is improved, but it causes a sense of foreign body when sleeping on the side
Solution Approach 1:
The side parts near the temple are designed with local quality differentiation: the internal contact surface uses thin, soft material for comfort when sleeping on the side, while the external shell maintains adequate thickness for structural integrity and light shielding. This local differentiation resolves the contradiction between strength and comfort.
Solution Approach 2:
The side parts incorporate flexible, thin film materials on the contact surfaces, providing structural integrity where needed while ensuring comfort when sleeping on the side. The flexible material adapts to the head contours, eliminating the foreign body sensation.

AI summary
The present disclosure relates to the technical field of eye masks, and in particular, to an improved light-shielding eye mask, including a surface protective layer, an eye contact layer, and a fixing strap. Left and right sides of the surface protective layer are respectively connected to the fixing strap. The fixing strap is provided with an adjustment buckle for adjusting the length of the fixing strap, making it easy to adjust the tightness of the eye mask. The side edges of the periocular contact surface of the eye mask are designed in a vertical I-shape with a relatively thin thickness, bringing less sense of foreign body when sleeping on the side and better comfort.
