Foldable Mirror Panels for Full-Length Reflection in Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a compact, portable mirror that provides a full-height or three-quarter length reflective surface for personal use, such as in a restroom, which is not met by existing tiny make-up mirrors.
Innovation Solution
A foldable compact mirror apparatus comprising multiple thin, lightweight, and robust planar mirror elements interconnected via a flexible backing support element, with attachment means for releasable attachment to an upright surface, allowing the mirror to be folded and stored in a small space while providing a full-length reflective surface when unfolded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If multiple mirror elements are interconnected to form a full-length mirror, then the reflective surface area is increased, but the portability and compactness deteriorate
Solution Approach 1:
The full-length mirror is divided into multiple separate mirror elements (typically 3-4 elements) that can be folded together like an accordion. Each mirror element is a smaller rectangular mirror that, when folded together in a zigzag pattern, creates a continuous full-length reflective surface. This segmentation allows the mirror to be collapsed into a compact form for portability while maintaining full-length reflection capability when deployed.
Solution Approach 2:
The mirror elements are designed to nest within each other when folded, with each subsequent mirror element fitting into the space created by the previous element. The flexible backing support enables the mirrors to be folded into a compact nested configuration that minimizes storage volume, similar to how nested dolls fit one inside another, while still providing full-length coverage when unfolded.
2Weight of moving object
If thin planar mirror elements are used to reduce weight, then the portability is improved, but the structural strength and robustness deteriorate
Solution Approach 1:
The mirror elements are constructed using thin flexible backing material (such as flexible circuit board or flexible polymer) that supports the reflective coating. This thin-film construction dramatically reduces the weight and thickness of each mirror element compared to traditional rigid glass mirrors, while the flexibility allows the structure to bend and fold without breaking. The thin backing film provides sufficient structural integrity for portable use while maintaining the reflective surface.
3Ease of operation
If mirror elements are spaced apart to allow folding, then the foldability is improved, but the manufacturing precision and alignment deteriorate
Solution Approach 1:
A flexible backing support structure serves as an intermediary element that connects and spaces the mirror elements at appropriate intervals. This backing support (flexible circuit board or polymer) provides the mechanical framework that enables folding while maintaining proper spacing and alignment between mirror elements. The flexible nature of the backing allows it to bend during folding while the rigid mirror elements remain properly positioned and aligned when the mirror is in use.

AI summary
Foldable compact mirror apparatus (10) comprises at least three planar mirror elements (12) which are foldably interconnected so that the planes of the mirror elements (12) can lie in parallel or substantially in parallel with each other, and attachment means (16) for releasably attaching the mirror elements (12) to an upright surface. Preferably, the mirror elements (12) have different widths to provide a tapering appearance and reduced weight during transport.
