Aircraft Crew Mirror Layout for Pocket Size and Clear Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirrors for aircraft crew members become bulky when compacted for pocket storage, reducing their effective mirror surface area due to the interference of coupling tools, leading to unstable grip and reduced functionality.
Innovation Solution
A vertically long mirror design with a through-hole positioned eccentrically or as a long hole extending from the center, allowing the coupling tool to be inserted without obstructing the mirror surface, ensuring a larger effective mirror area while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mirror size is reduced to eliminate bulge in the pocket, then the compactness is improved, but the effective mirror surface area is reduced
Solution Approach 1:
The through-hole is positioned asymmetrically (eccentrically) relative to the mirror surface, specifically at one end of the mirror in the longitudinal direction. This asymmetric placement ensures that the coupling tool passes through a location that does not interfere with the mirror surface area, allowing the mirror to maintain a compact size while preserving maximum effective reflection area.
2Shape
If the through-hole is positioned at the center of the mirror, then the structural symmetry is improved, but the grip stability is worsened due to coupling tool interference
Solution Approach 1:
The through-hole is deliberately positioned asymmetrically (eccentrically) at one end of the mirror rather than at the center. This asymmetric placement moves the coupling tool away from the gripping area, eliminating interference with the user's fingers and ensuring stable grip while maintaining ease of operation.
3Ease of operation
If the through-hole is positioned to allow stable grip, then the ease of operation is improved, but the mirror surface area is reduced due to coverage
Solution Approach 1:
The through-hole is positioned at the end of the mirror in the longitudinal direction, utilizing the longitudinal dimension to separate the coupling tool passage from the mirror surface area. This dimensional separation allows the coupling tool to pass through without covering the mirror surface, maintaining both grip stability and maximum mirror area.

AI summary
Provided is a mirror for aircraft crew members, whereby a large effective surface area of the mirror surface can be maintained during use even though the mirror is compact and does not feel bulky when placed inside a pocket. A mirror main body (2) of the mirror (1) for aircraft crew members is formed in a vertically long shape, said mirror (1) being held together with at least a key (9), by a coupling tool (8). A through-hole (7) is provided in an end section in the longitudinal direction of this mirror main body (2), at an eccentric position on one side away from the center (CW) in the width direction. The coupling tool (8) is inserted into this through-hole (7). The through-hole (7) can be a long hole (7A) that extends from the center (CW) in the width direction towards both sides.
