Remote Control Macro Instructions and Limited Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern entertainment systems with multiple components leads to difficulties in maintaining operable configurations, often resulting in inadvertent system inoperability due to user errors, which increases support calls for programming distributors and complicates the use of universal remote controls.
Innovation Solution
A remote control with a limited mode that restricts user access to commands that could render the system inoperable, allowing only predetermined safe configurations, and a macro instruction feature to simplify issuing multiple commands with a single user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a universal remote control is used to operate multiple components, then the ease of operation is improved, but the device complexity increases and users may inadvertently change settings
Solution Approach 1:
The remote control is divided into two distinct modes: normal mode and limited mode. This segmentation allows the same physical device to provide different levels of control functionality, simplifying the user interface while managing complexity through mode-based organization rather than multiple physical devices.
Solution Approach 2:
The remote control dynamically changes its operational characteristics based on the selected mode. In limited mode, certain commands are restricted or blocked, while in normal mode, full control is available. This dynamic behavior allows a single device to adapt to different user needs and skill levels.
2Reliability
If multiple commands are required to operate the entertainment system, then the reliability is improved by preventing accidental changes, but the ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-configuring macro instructions that execute multiple commands in sequence. When a user activates a macro, the remote control automatically performs the series of operations needed to achieve the desired outcome, preventing accidental intermediate changes while maintaining simplicity for the user.
Solution Approach 2:
Multiple individual commands are merged into a single macro instruction. This combining allows complex operations to be executed with a single user action, improving ease of operation while the underlying multi-step process maintains reliability by ensuring proper sequencing and preventing accidental changes.
3Adaptability or versatility
If users have full access to all commands, then the adaptability is improved, but the likelihood of inadvertent configuration changes increases
Solution Approach 1:
The remote control dynamically adjusts the set of available commands based on the operational mode. In limited mode, only safe commands are enabled, while in normal mode, full command access is provided. This dynamic adaptation allows the system to balance versatility and reliability based on user needs.
Solution Approach 2:
Different parts of the command set have different accessibility properties. Certain commands are restricted in limited mode while others remain available, creating local quality variations in command accessibility. This allows the system to maintain adaptability for essential operations while protecting against inadvertent changes in critical configuration areas.
4Reliability
If a limited mode is implemented to prevent accidental changes, then the reliability is improved, but the ease of operation worsens due to mode selection requirements
Solution Approach 1:
The system performs preliminary action by automatically selecting the appropriate mode based on the operational context or user preferences configured in advance. This eliminates the need for users to manually select modes during operation, maintaining reliability while preserving ease of use.
Solution Approach 2:
The remote control serves itself by automatically managing mode selection based on predefined criteria or user preferences. This self-service capability removes the burden of mode selection from the user while maintaining the reliability benefits of limited mode operation.

AI summary
A remote control and method of programming a remote control for controlling components in an entertainment system are disclosed. The remote control may operate in multiple modes including a limited mode that prevents the remote control from sending predetermined commands to one or more components, even when instructed to do so by the user. In addition, the remote control may issue one or more commands to each component in response to a single user input.
