Window Sill Heliostat With Reversible Wind-Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window reflectors or heliostats lack reversible rigid attachment to window sills and do not utilize ultra-lightweight biplanar reflective members with high reflectivity, leading to detachment issues during windy conditions and inadequate light reflection into rooms.
Innovation Solution
A reversibly attachable window sill heliostat featuring a lightweight biplanar reflective member with 95% or greater reflectivity, attached using hook-and-loop or hook-and-hook strips or fasteners, ensuring secure attachment and effective light reflection into rooms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing window reflectors are used, then light reflection function is provided, but they detach during windy conditions due to lack of secure attachment
Solution Approach 1:
The patent changes the weight parameter of the reflective member, making it ultra-lightweight (two pounds or less). This parameter change allows the reflector to be securely held by simple attachment means (hook and loop strips or attachment fasteners) without detaching during windy conditions, while avoiding the complexity of heavy-duty attachment mechanisms required for traditional heavier reflectors.
2Illumination intensity
If traditional reflective members are used, then basic light reflection is achieved, but reflectivity is insufficient to effectively illuminate rooms
Solution Approach 1:
The patent employs composite material construction for the reflective member, combining lightweight structural material with a highly reflective surface coating achieving 95% or greater reflectivity. This composite approach enables effective room illumination while maintaining ultra-lightweight status and simplifying attachment requirements.
Solution Approach 2:
The patent changes the reflectivity parameter of the reflective surface to 95% or greater, significantly improving light reflection intensity for effective room illumination. This parameter change is achieved through advanced surface coating or material selection without substantially increasing manufacturing complexity.
3Reliability
If heavy reflective members are used, then structural stability is improved, but attachment security decreases during windy conditions
Solution Approach 1:
The patent inverts the traditional approach by changing the weight parameter to ultra-lightweight (two pounds or less). Counterintuitively, this weight reduction improves attachment security because the lightweight reflector can be securely held by simple attachment means (hook and loop strips or attachment fasteners) without requiring complex heavy-duty mounting mechanisms, while still maintaining stability during windy conditions.

AI summary
A window reflector or heliostat is disclosed that is reversibly installed onto a window sill in order to reflect a view of the sun or sunlight into a room in a building. Window reflector or heliostat is a reflective member that is reversibly rigidly attached to a window sill on a window in a room. Window reflector or heliostat is an ultra-lightweight specially shaped biplanar reflective member with a reflectivity of 95 percent or greater at ninety degree incidence. Biplanar reflective member may be a one-piece assembly or a two-piece assembly with adjustable hinges. Window reflector or heliostat is reversibly attachable to the window sill using hook or loop attachment strips or window sill attachment fasteners.
