Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If power consumption records are compared directly between periods with and without energy-saving control, then evaluation of energy-saving effects can be performed, but accuracy of comparison deteriorates due to environmental differences such as temperature
Solution Approach 1:
The patent applies parameter changes by correcting power consumption records based on environmental parameters (temperature, humidity) to enable accurate comparison. The system calculates corrected power consumption values that account for environmental variations, allowing fair comparison between periods with different environmental conditions.
Solution Approach 2:
The patent introduces an intermediary correction mechanism that mediates between raw power consumption records and comparable values. The correction unit acts as an intermediary that processes raw records through environmental factor analysis to produce corrected records suitable for accurate comparison.
2Measurement precision
If multiple types of corrections are applied to power consumption records, then evaluation accuracy from various viewpoints is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the correction process into distinct functional units: a correction unit that performs environmental condition correction and an energy-saving correction unit that handles energy-saving measure corrections. This segmentation allows multiple correction types to be applied systematically while maintaining manageable system complexity.
Solution Approach 2:
The patent implements dynamics by allowing flexible selection and combination of different correction types based on evaluation needs. The system can dynamically apply environmental condition correction, energy-saving correction, or both, depending on the specific evaluation purpose, making the system adaptable without requiring all correction mechanisms to be permanently active.

AI summary
[Object] To correct a power consumption record in a period in which energy-saving control is performed and a power consumption record in a period in which the energy-saving control is not performed in accordance with a purpose of the comparison, and to enable evaluation of power consumption from various viewpoints.[Solution] A terminal device configured to evaluate power consumption of equipment includes a communication control unit configured to acquire a power consumption record of the equipment, and a processing unit configured to output data related to power consumption records before and after an energy-saving operation of the equipment. The processing unit performs correction I and correction II (II′) to make one of a power consumption period in an operation period before the energy-saving operation and a power consumption record in an operation period after the energy-saving operation comparable with the power consumption record in the other operation period, and then outputs data related to the power consumption records before and after the energy-saving operation.
