Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power consumption is reduced through technological improvement, then energy efficiency is improved, but user awareness and behavioral change are not achieved
Solution Approach 1:
The system provides real-time feedback to users by displaying estimated CO2 emission amounts and power consumption information on the operation unit. This feedback mechanism allows users to see the environmental impact of their printing actions and adjust behavior accordingly, resolving the contradiction between technological energy efficiency and user awareness.
Solution Approach 2:
The control unit acts as an intermediary that translates raw power consumption data into meaningful environmental impact information (CO2 emission estimates) that users can understand and act upon. This intermediary function bridges the gap between technical energy metrics and user comprehension, enabling behavioral change.
2Measurement precision
If detailed power consumption measurement and simulation are implemented, then accuracy of energy reduction estimation is improved, but device complexity increases
Solution Approach 1:
The control unit serves as an intermediary that performs the complex calculations of power consumption measurement and CO2 emission estimation, then presents simplified information to users. This mediates between the need for precise measurement and the desire to avoid increasing user-facing system complexity.
Solution Approach 2:
The system automatically performs power consumption measurements and simulations without requiring user intervention or complex user setup. The control unit self-manages the data collection, calculation, and presentation processes, reducing the operational complexity users would otherwise need to handle.

AI summary
In order to provide an action indicator for encouraging a user to use an image forming apparatus (101) in an environmentally friendly manner, the image forming apparatus (101) includes a printing unit (104) configured to perform printing on a print medium based on image data; and a controller (103) configured to control the printing unit (104) based on a job involving the printing. The controller (103) causes the printing unit (104) to print by applying printing settings to image data related to the job, and outputs information on an amount of power required to execute the job, the amount of power being an amount of power per processing unit on the condition that the print setting is applied.
