Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Producing light control panels with metallic reflective surfaces is time-consuming and costly due to the need for special deposition equipment and lamination of large numbers of sheets with adhesive agents, making mass production expensive.
Innovation Solution
A method using independent mirror sheets with metallic reflective surfaces attached to transparent sheets, joined with a UV curing-type or thermosetting adhesive agent, which simplifies the production process and reduces costs by eliminating the need for complex deposition and extensive lamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metallic reflective layer is deposited on the surface of a transparent plate using conventional methods, then a light control panel with reflective properties is produced, but the production process becomes time-consuming and expensive due to the need for special deposition apparatus
Solution Approach 1:
The patent replaces expensive, durable metallic reflective layers with inexpensive mirror sheets that can be easily attached and removed. These mirror sheets serve as disposable or reusable reflective elements that eliminate the need for costly vacuum deposition processes while maintaining the necessary light control functionality.
Solution Approach 2:
The patent substitutes the mechanical/chemical deposition process with a simple mechanical attachment method. Instead of using vacuum deposition apparatus to deposit metallic layers, the invention uses mirror sheets that are mechanically attached to transparent plates using adhesive agents, significantly simplifying the manufacturing process.
2Reliability
If large numbers of sheets with metallic reflective surfaces are laminated together, then a functional light control panel is formed, but the lamination process requires adhesive agents and becomes complex and time-consuming
Solution Approach 1:
The patent extracts the reflective function from the bulk lamination structure by using independent mirror sheets attached to transparent plates. This allows the reflective elements to be separately prepared and then simply attached, eliminating the need for complex multi-layer lamination processes while maintaining structural integrity.
Solution Approach 2:
The mirror sheets are prepared in advance as separate components with their reflective surfaces already formed. This preliminary preparation allows for parallel production of mirror sheets and transparent plates, which are then quickly assembled together, significantly reducing the total production time compared to sequential lamination processes.
3Reliability
If conventional deposition methods are used to create reflective surfaces, then metallic reflective layers are formed, but the process is not suitable for inexpensive mass production
Solution Approach 1:
The patent uses inexpensive mirror sheets that can be mass-produced through simple manufacturing processes rather than requiring costly vacuum deposition for each individual panel. These mirror sheets can be produced in large quantities and then attached to transparent plates, enabling inexpensive mass production while maintaining adequate reflective surface quality.
Solution Approach 2:
The patent changes the production approach from a process-oriented method (vacuum deposition) to a component-oriented method (attaching pre-made mirror sheets). This parameter change in the manufacturing strategy enables parallel production and assembly, significantly improving productivity and enabling mass production at lower costs.

AI summary
A method for producing a light control panel includes a first step of forming a block 19 in which transparent sheets 16 of glass, ceramic or transparent plastic and mirror sheets 17 each having a metallic reflective surface on one side or both sides are alternately stacked and laminated, and a second step of forming a first light control panel 13 and a second light control panel 14 to be stacked with planar light-reflective portions 11, 12 of each of the first and the second light control panels 13, 14 in a crossed state, the first and the second light control panels 13, 14 being arranged opposed to each other, by cutting out from the block 19 on a surface crossing the transparent sheets 16 and the mirror sheets 17 in a manner that makes the thickness of a cutout constant.
