Display Control Device for Power-Constrained Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as digital cameras, face usability issues due to limited operations caused by varying power supply capabilities from different power sources and changing power consumption based on accessories and settings, leading to unintended limitations and reduced usability.
Innovation Solution
A display control device that determines and displays usage conditions for an electronic device, considering factors like power source type, lens type, recording settings, and power consumption, ensuring maximum power consumption does not exceed available power without limiting operations, using a processor and memory to acquire and determine these conditions and control the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device supports multiple electric power sources with varying power supply capabilities, then the device can operate in more environments and has higher versatility, but the device may experience unintended operation limitations and reduced usability when power consumption exceeds available power
Solution Approach 1:
The device performs preliminary determination of usage conditions before operation. The determining unit calculates maximum electric power consumption based on multiple factors (power source type, lens type, recording settings, etc.) and identifies conditions where power consumption remains within available power limits. This preliminary analysis prevents power-related operation limitations during actual use.
Solution Approach 2:
The display control device provides feedback to users about usage conditions. The control unit causes the display unit to show determined usage conditions, informing users about safe operating parameters. This feedback loop enables users to adjust settings to avoid power-related limitations while maintaining device versatility.
2Ease of operation
If the device displays detailed usage conditions to help users understand power constraints, then usability is improved, but the device complexity increases due to additional determination and display control functions
Solution Approach 1:
The determining unit performs multiple determination tasks using a unified approach. It simultaneously evaluates maximum electric power consumption across various factors (power source type, lens type, recording settings, image quality priority) and identifies usage conditions that satisfy power constraints. This multi-functional determination reduces the need for separate control mechanisms for each factor.
Solution Approach 2:
The system automatically determines and displays usage conditions without requiring complex user input or manual calculations. The acquiring unit collects necessary parameters, the determining unit processes them to identify safe operating conditions, and the control unit presents the results. This self-service approach simplifies the user interface while maintaining comprehensive power management.

AI summary
A display control device is related to an electronic device, the display control device including: an acquiring unit configured to acquire conditions of a first factor that is at least one factor out of a plurality of factors, the conditions corresponding to a selection performed by a user; a determining unit configured to determine conditions of a second factor out of the plurality of factors that is different from the first factor on a basis of conditions of the first factor acquired by the acquiring unit, the conditions being conditions under which maximum electric power consumption is not more than suppliable electric power without operation of the electronic device being limited in a predetermined situation; and a control unit configured to control a display unit to display conditions of the second factor determined by the determining unit.
