View Changer With Dual Reflectors for Privacy and Lateral Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blinds struggle to provide a view from the inside to the outside while blocking direct sunlight and compromise privacy when facing buildings.
Innovation Solution
A view changer with vertically aligned indoor and outdoor reflectors that adjustably reflect external light to create vertically parallel-segmented views without left-right reversal, incorporating a frame that can be reversed and adjustable levers for precise angle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the blind is angled to block direct sunlight, then privacy is improved, but the ability to see external view deteriorates
Solution Approach 1:
The blind is divided into multiple slats that can be independently angled. By segmenting the blind structure, different slats can be positioned at different angles - some to block sunlight and protect privacy, while others maintain viewability. The slats are arranged in segments that allow selective light blocking while preserving visual access to the external environment.
Solution Approach 2:
The blind transitions from a two-dimensional flat structure to a three-dimensional configuration by angling the slats. This dimensional change allows the blind to block light from certain directions (improving privacy) while maintaining transparency from other directions (preserving view). The slats are positioned at specific angles relative to the window plane, creating spatial separation between light-blocking function and view-maintaining function.
2Loss of information
If the slats are opened to provide a view, then external view visibility is improved, but privacy protection deteriorates
Solution Approach 1:
Different portions of the blind structure are given different functional qualities. Some slats are designed and positioned primarily for viewability, while others are optimized for privacy protection. The local arrangement of slats creates zones with different properties - some areas prioritize seeing outside, while adjacent areas prioritize blocking external view, allowing both functions to coexist within the same blind system.
3Ease of manufacture
If a conventional blind structure is used, then manufacturing simplicity is improved, but the ability to block forward view while allowing lateral view deteriorates
Solution Approach 1:
The blind incorporates adjustable and reconfigurable elements that allow it to adapt to different viewing and privacy requirements. The slats can be positioned at various angles and configurations, transforming a static conventional blind into a dynamic system that can respond to different environmental conditions and user needs. This adaptability is achieved through mechanical linkages and adjustment mechanisms that maintain manufacturing feasibility while enabling versatile functionality.
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
Enables privacy protection by blocking forward views while allowing lateral external views, enhancing aesthetic appeal through segmented reflections, and functioning as a conventional blind.
Implementation Method 1
outdoor reflectors arranged at rear sides of the respective indoor reflectors and configured to primarily reflect incident light from an external view to adjacent indoor reflectors
Implementation Method 2
indoor reflectors may block a forward view and secondarily reflect the light from the external view already reflected by the outdoor reflectors

AI summary
The view changer includes a frame detachably fitted into a window so as to be optionally reversible in a left-and-right direction, a plurality of indoor reflectors vertically aligned in parallel between a top frame and a bottom frame of the frame, and a plurality of outdoor reflectors arranged at rear sides of the respective indoor reflectors and primarily reflecting incident light from an external view to adjacent indoor reflectors, wherein the outdoor reflectors are configured so that a reflection angle for reflecting the light from the external view is adjustable relative to an angle of the indoor reflectors, and the indoor reflectors blocks a forward view and secondarily reflects the light from the external view already reflected by the outdoor reflectors, thereby allowing the light from the external view to enter an interior space so that the external image is seen in the form of vertically parallel-segmented views.
