Wearable Exposure Calculator Watch with Rotatable Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Photographers face challenges in quickly and conveniently calculating appropriate camera shutter speed and aperture settings for given ISO speeds to achieve proper photographic exposure, often relying on time-consuming chart references.
Innovation Solution
A wearable device, such as a watch, with a rotatable bezel and markings for camera aperture numbers and shutter speed values, allows users to align settings for appropriate exposure by rotating the bezel to position the aperture reference indicator next to a desired aperture number, with corresponding ISO speed and shutter speed values displayed for proper exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If photographers use external charts or references to calculate exposure settings, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The watch integrates multiple functions into a single device: it serves as both a timepiece and an exposure calculator. The watch face incorporates aperture markings, shutter speed markings, and ISO indicators, allowing photographers to calculate exposure settings directly from their wrist without needing separate charts or references.
Solution Approach 2:
The watch enables photographers to independently determine exposure settings using the integrated markings and indicators on the watch face itself. The device serves the photographer's needs autonomously by providing all necessary exposure calculation information in one location, eliminating the need to consult external references.
2Measurement precision
If photographers carry external reference materials, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple exposure calculation tools into a single watch device. The aperture markings, shutter speed markings, and ISO indicators are integrated onto the watch face, merging what would traditionally be separate reference materials into one unified instrument that photographers already wear.
Solution Approach 2:
The watch serves dual purposes: telling time and calculating exposure settings. By making the watch multi-functional, the invention eliminates the need for photographers to carry additional reference materials, thereby reducing overall device complexity while maintaining measurement precision.
3Measurement precision
If photographers manually calculate exposure settings, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The watch face is pre-configured with aperture markings, shutter speed markings, and ISO indicators in predetermined relationships that correspond to standard exposure calculations. This preliminary arrangement of information allows photographers to quickly determine exposure settings by simply aligning the markings, eliminating the need for manual calculations and speeding up the photography process.
