Electronic Device Search Condition Inheritance for Media Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When the search conditions for content are reused after a change in the recording medium, there is a likelihood that the content satisfying the search conditions may not exist, leading to unnecessary searches and failure to display matching images, as the search conditions for items like date and folder can differ significantly between media.
Innovation Solution
An electronic device with a setting unit, storage control unit, and search unit that stores and reuses search conditions, where the stored search condition is used as a candidate for the first search item but not for the second search item when the recording medium changes, ensuring that search conditions for date and folder are reset to initial values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all stored search conditions are reused after recording medium change, then user operation is simplified, but search accuracy deteriorates because conditions may not match the new medium
Solution Approach 1:
The patent segments search conditions into two categories: those suitable for inheritance (e.g., file type, rating) and those requiring reset (e.g., date, folder). This segmentation allows selective reuse of conditions based on their compatibility with recording medium changes, resolving the contradiction between ease of operation and search accuracy.
Solution Approach 2:
Different search conditions are treated with different qualities of inheritance. Some conditions maintain their inherited values while others are reset to initial states. This local differentiation ensures that each condition is handled appropriately according to its nature, achieving both operational convenience and search precision.
2Loss of time
If all stored search conditions are reused after recording medium change, then operation time is reduced, but search productivity deteriorates due to unnecessary searches
Solution Approach 1:
By segmenting search conditions into inheritable and non-inheritable categories, the system avoids performing unnecessary searches with inappropriate conditions while still reusing valid conditions, thus maintaining both time efficiency and search productivity.
Solution Approach 2:
The system performs partial reuse of search conditions rather than complete reuse or complete reset. This partial action approach optimizes the balance between reducing operation time and maintaining search effectiveness by applying inheritance only where beneficial.
3Measurement precision
If search conditions are completely reset after recording medium change, then search accuracy is maintained, but user convenience deteriorates due to repeated setup
Solution Approach 1:
Instead of uniform resetting, the system applies local quality differentiation where only specific conditions (date, folder) are reset while others (file type, rating) retain their values. This resolves the contradiction by maintaining accuracy for critical conditions while preserving convenience for stable conditions.
Solution Approach 2:
The search conditions are segmented into those requiring reset and those allowing inheritance, enabling the system to maintain accuracy where needed while avoiding unnecessary setup operations, thus balancing precision and user convenience.

AI summary
An electronic device comprising: a setting unit configured to set a search condition including a first search item and a second search item based on a user operation; a storage control unit configured to perform control to store the search condition set by the setting unit; and a search unit configured to search for a content based on the search condition set by the setting unit from a storage destination serving as a search target, wherein in a case in which a storage destination serving as a search target is changed after the search condition is stored by control of the storage control unit, the setting unit 1) uses a stored search condition as a setting candidate as for the first search item and 2) does not use a stored search condition as a setting candidate as for the second search item.
