Solution Overview

Problem

Existing remote control devices face challenges in efficiently managing multiple functions and orientations, leading to visual clutter and inefficient use of infrared transmission, particularly when requiring text entry or complex appliance control.

Innovation Solution

A multi-sided remote control device with a housing featuring two or more sides of activable key elements, integrated infrared transmitters, and an orientation sensor that selects the appropriate transmitter based on the device's orientation and user input, allowing for efficient command transmission across various orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple infrared transmitters are provided on different sides of the remote control, then the device can operate in various orientations, but the device complexity increases

Engineering Contradiction:
Improveoperational orientationVSAvoidtransmitter configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically selects which infrared transmitter to activate based on the detected orientation of the remote control. The processing device receives orientation data from the sensor and automatically switches between transmitters accordingly, making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The remote control automatically determines its own orientation using the integrated sensor and selects the appropriate transmitter without user intervention. The system self-configures based on physical orientation, eliminating the need for manual mode switching.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If multiple infrared transmitters are provided on different sides of the remote control, then the device can operate in various orientations, but the manufacturing cost increases

Engineering Contradiction:
Improveoperational orientationVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system dynamically selects which infrared transmitter to activate based on the detected orientation of the remote control. The processing device receives orientation data from the sensor and automatically switches between transmitters accordingly, making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If all infrared transmitters are activated simultaneously, then all functions are available in all orientations, but energy consumption increases

Engineering Contradiction:
Improvefunctional availabilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically selects which infrared transmitter to activate based on the detected orientation of the remote control. The processing device receives orientation data from the sensor and automatically switches between transmitters accordingly, making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Instead of activating all transmitters simultaneously, the system activates only the transmitter necessary for the current orientation. This partial action approach uses only the required subset of transmitters, reducing energy consumption while maintaining full functionality when needed.

Inventive Principle:
Principle #16Partial or excessive action

4Ease of operation

If multiple keypads are distributed across multiple surfaces, then visual clutter is reduced, but the device complexity increases

Engineering Contradiction:
Improvevisual clarityVSAvoidkeypad configuration
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The keypad functionality is segmented across multiple surfaces of the remote control. Different sets of buttons are placed on different sides, allowing functions to be physically separated and reducing visual clutter on any single surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution moves from a two-dimensional keypad layout to a three-dimensional multi-surface configuration. By utilizing the vertical and lateral dimensions of the remote control body, multiple keypads are distributed across different surfaces and orientations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A multi- -sided controlling device automatically makes keys on one or more sides of the controlling device active as a function of an operating mode of the controlling device. One or more sides of such a multi-sided controlling device may also have at least one keycap behind which is positioned an IR transmitter usable when another side of the controlling device is active.
