Programmable Remote Control with Preset Memory for TV Input Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern television receivers with numerous inputs and modes can confuse users, making it difficult for non-technophiles to easily switch back to desired channels or inputs after using connected devices like DVD players, due to complex remote control operations and unclear input designations.
Innovation Solution
A remote control device with a transmitter, controller, and programmable switches allows users to preset settings, enabling easy selection and recall of desired modes and inputs using a 'set home' feature, which stores user-selected data in memory and automatically restores the television receiver to previous settings with a 'home' button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the television receiver has multiple inputs and modes to support various electronic equipment, then the adaptability and versatility of the device is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent applies preliminary action by allowing users to preset and store desired mode and input combinations before needing them. The memory device stores these pre-configured settings, so when a user wants to return to a previous viewing state, the system automatically restores the stored mode and input without requiring the user to manually navigate through multiple inputs and modes again.
2Adaptability or versatility
If the remote control device controls many inputs and electronic components, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent reduces remote control complexity by implementing preliminary action through preset storage. Instead of requiring users to manually navigate through numerous inputs and modes each time, the system pre-stores complete viewing configurations (mode + input combinations) in memory. A single button press restores the entire configuration, dramatically simplifying the remote control operations despite the system supporting many inputs and components.
3Reliability
If the user needs to manually navigate through complex remote control operations to switch inputs, then the device functionality is maintained, but the loss of time increases
Solution Approach 1:
The patent addresses time loss by implementing preliminary action through automatic restoration. The system pre-stores desired mode and input configurations in memory, so when a user needs to switch back to a previous viewing state, the controller automatically retrieves and applies the stored configuration without requiring manual navigation. This maintains full device functionality while dramatically reducing the time required to switch between inputs and modes.
Data Source
AI summary
A control device for a television receiver having a user-controlled restore function. The control device has a user-programmable switch for enabling the user to store user-selected data in a memory, including TV input data and channel data. A restore switch is provided for enabling a microprocessor to transmit digital data corresponding to the user-selected data. Actuation of the restore switch will restore the television receiver to a state of operation responsive to the user-selected stored data based on the user's settings of the user-programmable switch.
