Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eyeshades are used, then light blocking function is provided, but they cannot be adjusted to fit individual face shapes and head sizes, causing discomfort and light leakage
Solution Approach 1:
The eyeshade is divided into multiple detachable modules including eye covers, head band, and connector portions. This segmentation allows each component to be independently adjusted and configured to fit different head sizes and face shapes while maintaining effective light blocking through the modular assembly.
Solution Approach 2:
The eyeshade incorporates adjustable and reconfigurable components that can be dynamically modified to suit different users. The detachable modules can be assembled, disassembled, and repositioned to achieve optimal fit and light blocking performance for various head sizes and face shapes.
2Ease of operation
If conventional eyeshades are used, then light blocking function is provided, but they cause discomfort and pressure on the head
Solution Approach 1:
By segmenting the eyeshade into detachable modules connected by flexible connector portions, the design distributes weight and pressure more evenly across the head, reducing discomfort while maintaining light blocking effectiveness through proper positioning of each module.
Solution Approach 2:
The connector portions and head band utilize flexible materials that can conform to the contours of different heads, providing comfort through adaptability while maintaining the structural integrity needed for effective light blocking.
3Ease of operation
If modular eye covers with hook-and-loop straps are used, then quick attachment and detachment is enabled, but device complexity increases
Solution Approach 1:
The hook-and-loop fastening system serves multiple functions: securing eye covers to head band, adjusting fit, and enabling quick attachment/detachment. This universal fastening mechanism simplifies the overall design by using a single type of connection for multiple purposes, reducing the complexity that would otherwise arise from different fastening methods.
4Ease of operation
If variable thickness in eye covers is implemented, then wearing comfort is enhanced, but manufacturing complexity increases
Solution Approach 1:
The eye covers feature variable thickness with different densities in different regions - thicker and softer at contact points for comfort, and thinner elsewhere for lightweight design. This local quality variation is achieved through modern manufacturing techniques that can efficiently produce comfort-optimized structures without significantly increasing overall manufacturing complexity.
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 modular eyeshade enhances comfort and effectiveness in blocking light, relieving pressure, improving sleep quality, and providing additional functions like awakening and therapy, ensuring a secure and comfortable fit for various users.
Implementation Method 1
an eyeshade which increases the friction between the eyeshade and the head of a wearer, thereby preventing the eyeshade from slipping off the head
Implementation Method 2
provides a proper elastic tightening effect

AI summary
An eyeshade (10) includes a head band (12) and two eye covers (20). The head band (12) includes a middle section (14), an end section (15) horizontally extending from the middle section (14), and at least three first hook-and-loop straps (142). Two of the three first hook-and-loop straps (142) are arranged on an inner surface (141) of the middle section (14). Each eye cover (20) includes an inner pad (22) and a covering portion (24). Each inner pad (22) includes an inner pad outer surface (221) and a depression (222). The covering portion (24) includes a cavity (241) corresponding to the depression (222) and includes a second hook-and-loop strap (242). Each of the second hook-and-loop straps (242) is removably attached to the corresponding first hook-and-loop strap (142). The eyeshade (10) has modular replaceable eye covers (20) which can be quickly attached to head band (12) to provide various functions as required.
