Waterproof Pant Leg Sheath with Stirrup Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rain gear fails to effectively protect the lower pant legs and shoes from rain and condensation, especially in heavy downpours or windy conditions, where rain often penetrates and soaks these areas.
Innovation Solution
A waterproof sheath with a stirrup attachment that encases the pant leg and secures to the shoe, providing a water-resistant barrier and adjustable fastening systems for secure fit, made from materials like lightweight plastic, vinyl, or water-resistant fabrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional rain gear (umbrellas, raincoats) is used, then upper body protection is achieved, but lower pant legs and shoes remain exposed to rain
Solution Approach 1:
The protective gear is divided into separate components: an upper body raincoat and lower leg waterproof boot covers. This segmentation allows each component to independently protect specific body parts, solving the problem of exposed lower pant legs while maintaining overall system simplicity.
Solution Approach 2:
The waterproof boot covers are designed to be worn over existing shoes and pants, creating a nested protective system. The boot covers encase the lower pant legs and shoes, providing additional protection without requiring complete replacement of existing footwear or clothing.
2Object-affected harmful factors
If waterproof boot covers are added to protect lower legs, then rain protection is improved, but device complexity increases
Solution Approach 1:
The waterproof boot covers serve multiple functions simultaneously: they protect lower pant legs from rain, protect shoes from water ingress, and can be adjusted to fit different shoe sizes. This multi-functionality reduces the need for separate protective items for each body part.
Solution Approach 2:
The boot covers incorporate adjustable fastening mechanisms (straps, Velcro, or laces) that allow dynamic adaptation to different shoe sizes and leg circumferences. This adjustability ensures a secure fit across various users and footwear types without requiring multiple sizes of protective gear.

AI summary
A device for protecting a portion of a person's pant leg and shoe from exposure to rain is disclosed. The device includes a waterproof sheath for encasing a portion of the pant leg, the water-resistant sheath having an upper edge opposite a lower edge, and a front panel opposite a back panel, or alternatively of unibody construction encasing the entire leg. The upper edge of the sheath includes a lip for compressing against the pant leg. A stirrup attached to the lower edge of the sheath is included, the stirrup passing underneath a person's shoe or foot to secure the lower edge of the sheath to a lower portion of the pant leg. In a rainy environment, the device covers a person's lower pant leg to prevent the pant leg and/or the person's shoe from exposure to rain and other condensation.
