Terminal Option State Retention During Grade Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During a product selection operation, such as selecting a vehicle, changing the grade of the product often results in the options being reset to their initial state, requiring the user to reselect options, making the process cumbersome.
Innovation Solution
A terminal with a display device, input device, and control device that maintains the selected state of options when changing the product grade, ensuring that only the grade is updated while the options remain selected, facilitating the product selection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grade of the product is changed, then the price information is updated, but the selected state of options is reset to initial state
Solution Approach 1:
The control device stores the selection state of options before grade change occurs. When grade is changed, the stored option selection state is retrieved and applied to the new grade, preventing the need for users to reselect options and maintaining operational convenience while ensuring accurate price information display.
2Ease of operation
If the option selection state is maintained after grade change, then the product selection operation is facilitated, but the price information may become inaccurate
Solution Approach 1:
The control device calculates and displays price information based on the combination of the changed grade and the maintained option selection state. This feedback mechanism ensures that the displayed price accurately reflects the current configuration of grade and options, maintaining reliability while preserving user convenience.
3Reliability
If the user has to reselect options after changing grade, then the price information is accurate, but the selection process becomes cumbersome
Solution Approach 1:
The control device stores the selection state of options before grade change occurs. When grade is changed, the stored option selection state is retrieved and applied to the new grade, preventing the need for users to reselect options and maintaining operational convenience while ensuring accurate price information display.

AI summary
A terminal includes a display device configured to display a grade of a product and an option of the product, an input device configured to receive an operation for selecting the grade and an operation for selecting the option, and a control device configured to control the display device to display price information of the product in a state in which the grade and the option are selected. The grade includes a first grade and a second grade. The control device is configured to, in a state in which the first grade and the option are selected, when the input device receives an operation for changing grade selection from the first grade to the second grade, update a display of the price information to a display of the price information corresponding to the second grade while maintaining a selected state of the option selected in the first grade.
