Umbrella Protective Device with Vertical Shields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrellas and raincoats fail to provide full-body protection against weather elements, especially in windy conditions, and do not offer a customizable fit or adequate ventilation, leading to exposure of the lower body and discomfort due to moisture and heat retention.
Innovation Solution
A portable protective device with a collapsible umbrella and a telescopic stem, featuring a protective member that extends from the canopy to provide full-body coverage, including adjustable length and ventilation options, which can be retrofitted to standard umbrellas and includes a see-through, waterproof material for visibility and privacy, along with airflow conduits for ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional umbrellas are used, then protection from straight-falling rain is provided, but protection against wind-driven rain and snow is insufficient
Solution Approach 1:
The invention extends the protective coverage from a traditional two-dimensional canopy to a three-dimensional enclosure by adding vertical attachment shields that extend downward from the canopy edges. This dimensional extension creates a full-body protective environment that addresses wind-driven precipitation from all directions, not just overhead protection.
Solution Approach 2:
The protective device is divided into distinct functional segments: the traditional canopy for overhead protection, vertical attachment shields for side and lower body protection, and a modular structure that can be assembled in parts. This segmentation allows each component to address specific weather exposure vectors while maintaining overall system functionality.
2Object-affected harmful factors
If conventional raincoats are used, then protection from rain is provided, but ventilation is limited causing heat retention
Solution Approach 1:
The attachment shields incorporate localized ventilation features at specific positions (such as near the bottom edges or at strategic heights) while maintaining waterproof protection in other areas. This allows air circulation to reduce heat buildup in critical zones while preserving rain protection where needed most.
3Object-affected harmful factors
If conventional umbrellas are used, then overhead protection is provided, but lower body exposure occurs in windy conditions
Solution Approach 1:
The invention extends the protective coverage from a traditional two-dimensional canopy to a three-dimensional enclosure by adding vertical attachment shields that extend downward from the canopy edges. This dimensional extension creates a full-body protective environment that addresses wind-driven precipitation from all directions, not just overhead protection.
4Area of stationary object
If umbrellas with large canopy surface area are used, then overhead coverage is improved, but wind resistance decreases causing canopy lift
Solution Approach 1:
The vertical attachment shields act as counterbalancing elements that extend downward from the canopy edges. These shields provide aerodynamic stability by creating downward force that counteracts the upward lift generated by large canopy surface areas in windy conditions, allowing the umbrella to maintain both large coverage and wind resistance.

AI summary
A protective device configured to provide a user with body protection includes an umbrella having a canopy and a centrally positioned shaft extending from a center of the canopy. The shaft includes a telescopic stem configured to support the protective device when configured in its extended position. A plurality of umbrella spines extends from the centrally positioned shaft in a radial direction from the center of the canopy. Each umbrella spine has a proximate end originating adjacent the centrally positioned shaft and a distal end spaced apart from and opposite the proximate end. The distal end houses a telescoping rigid segment that is configured for radial extension from the distal end. The protective device further includes a protective member extending from a peripheral edge of the canopy. According to an aspect, the rigid segment is configured to support the protective member in the radially extended position.
