Remote Controller with Nested Rotating Dials for Program Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in conveniently accessing and reproducing recorded TV program data, particularly due to the need for frequent screen switching and complex operations in existing remote controllers for digital recording/reproducing devices, which can lead to recording errors and increased costs for real-time program information updates.
Innovation Solution
A remote controller with features such as a program data reproducing button that allows users to rotate to set desired times and days, a recommendation button, and power supply buttons for individual users, enabling the reproduction of recorded program data without screen switching and simplifying operations by sending remote signals to the digital recording/reproducing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users switch screens between TV screen and top menu screen to view recorded program data, then program data can be accessed, but user convenience deteriorates due to frequent screen switching and complex operations
Solution Approach 1:
The remote controller stores frequently accessed program data information (such as recently viewed programs or recommended programs) in its memory. When a user presses a button, the controller retrieves and sends the corresponding reproduction command directly to the digital recording/reproducing device, eliminating the need for users to navigate through menus and switch screens. This preliminary preparation of data access paths significantly reduces operation time and improves convenience.
2Reliability
If extra equipment is added to renew program information in real time, then recording accuracy improves, but cost increases
Solution Approach 1:
The system utilizes feedback from the electronic program list (EPG) data already present in the digital recording/reproducing device. The remote controller queries this existing EPG information to retrieve program details such as titles, broadcast times, and descriptions. By leveraging the feedback mechanism of the existing EPG system rather than adding separate real-time information renewal equipment, the invention maintains recording accuracy while avoiding increased device complexity and cost.
3Ease of operation
If conventional remote controllers are used for digital recording/reproducing devices, then basic operations are possible, but ease of operation deteriorates due to inability to access program data without screen switching
Solution Approach 1:
The remote controller is designed with multi-functionality to handle both basic remote control operations (power, volume, channel) and advanced program data access functions. It includes a database of program information, intelligent retrieval capabilities, and direct reproduction commands. This universal design allows the single remote controller to replace multiple separate functions, enabling users to access recorded program data as conveniently as controlling basic TV functions, thereby improving ease of operation without requiring additional specialized devices.

AI summary
There is provided a remote controller facilitating the operation concerning reproduction of recorded program data and having a user-friendly function. The remote controller (50) transmits an operation signal of a digital recording/reproducing device (10) which has recorded television programs. The remote controller (50) includes a power button (60) for turning on/off power of a TV for displaying the output data of the digital recording/reproducing device (10) and a reproduction button (80) for reproducing program data. The reproduction button includes: a first operation unit (81) which has time marks from 1 o'clock to 24 o'clock and can be rotated rightward and leftward; a second operation unit (82) which is formed on the first operation unit (81) with a smaller size than the outer diameter of the first operation unit (81),has time marks from Sunday to Saturday and can be rotated rightward and leftward; and a reproduction decision unit (83) formed on the second operation unit (82) with a smaller size than the outer diameter of the second operation unit (82) for deciding the day-of-week mark and the time mark specified by the first operation unit (81) and the second operation unit (82).
