Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized window treatments rely on non-renewable energy sources, which can be costly and environmentally unsustainable, and there is a need for a more efficient and sustainable power solution.
Innovation Solution
A motorized window treatment system powered entirely by solar energy, utilizing solar cells integrated into the bottom bar of the window treatment to charge an energy storage element, which then powers the motor drive unit through a dock mechanism when the covering material is in the raised position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If solar cells are integrated into the bottom bar to enable self-powering, then energy sustainability is improved, but device complexity increases due to additional components
Solution Approach 1:
The solar cells are integrated directly into the bottom bar structure, merging the power generation function with the existing structural component. This eliminates the need for separate power generation devices and reduces overall system complexity despite adding renewable energy capability.
Solution Approach 2:
The bottom bar serves multiple functions: it provides structural support for the window treatment, houses the motor drive unit, and incorporates solar cells for power generation. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity.
2Adaptability or versatility
If solar cells and energy storage elements are added to power the motor drive unit, then energy independence is improved, but manufacturing complexity increases
Solution Approach 1:
The solar cells, energy storage elements, and motor drive unit are combined into an integrated assembly that can be manufactured as a single unit or pre-assembled module. This integration simplifies the manufacturing process by reducing the number of separate assembly steps required in the field.
Solution Approach 2:
The solar cells and energy storage elements are pre-installed and pre-configured in the bottom bar during manufacturing. This preliminary action ensures proper positioning and electrical connections are established before installation, simplifying on-site manufacturing and reducing the complexity of field assembly.

AI summary
A motorized window treatment may include first and second mounting brackets and a window treatment assembly that includes a covering material and a bottom bar attached to the bottom end of the covering material. The bottom bar may include at least one solar cell attached to the bottom bar and a first energy storage element electrically coupled to the solar cell. The motorized window treatment may include a dock configured to be electrically coupled to a motor drive unit of the window treatment assembly, and the dock may be supported by the first mounting bracket. The bottom bar may be configured to be positioned adjacent to the dock when the covering material is in a raised position, such that the first energy storage element of the bottom bar is configured to discharge through the dock into a second energy storage element of the motor drive unit.
