Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras face difficulties in executing operations when buttons are difficult to visually recognize, especially in dark environments or when hard to manipulate, leading to erroneous operations.
Innovation Solution
An image capturing apparatus equipped with an image capture unit, a reproducing unit, and an attitude detecting unit that allows for predetermined operations to be executed when a specific attitude change pattern is detected, enabling easy operation without needing to visually recognize or manually manipulate buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are used for operation in dark environments, then visual recognition becomes difficult, but manual manipulation becomes error-prone
Solution Approach 1:
The patent replaces mechanical button pressing with an optical detection system. The attitude detecting unit uses sensors (such as accelerometers or gyroscopes) to detect the camera's orientation and movement patterns, substituting the mechanical interaction of pressing buttons with an automated sensing system that interprets physical movements to execute operations.
Solution Approach 2:
The camera system performs operations automatically based on detected attitude changes without requiring manual button input. The control unit interprets the detected attitude patterns and autonomously executes corresponding functions, allowing the system to serve itself by converting physical handling into operational commands.
2Ease of operation
If buttons are used for navigation and operation, then manual manipulation is required, but visual recognition becomes difficult in dark environments
Solution Approach 1:
The patent replaces the need for visual button recognition with an inertial sensing system. Instead of requiring users to see and press buttons, the attitude detecting unit captures spatial orientation data, and the control unit translates this into navigation commands, eliminating the visual dependency entirely.
Solution Approach 2:
The attitude detecting unit acts as an intermediary between the user's physical handling of the camera and the operational commands. Rather than direct button pressing, the sensor captures intermediate data about camera orientation and movement, which the control unit then interprets to execute the desired operations.
3Measurement precision
If manual button operation is used, then precise control is possible, but operation becomes difficult when buttons are hard to manipulate
Solution Approach 1:
The patent substitutes precise manual button pressing with precise attitude detection through sensors. The attitude detecting unit measures orientation changes with high precision, and the control unit maps these measurements to specific operations, maintaining precision while improving accessibility.
Solution Approach 2:
The patent transitions from one-dimensional button pressing (requiring fine motor skills and visual guidance) to three-dimensional attitude detection (utilizing spatial orientation in multiple axes). This dimensional shift allows operations to be controlled through natural hand movements and body orientation rather than precise finger manipulation.
