Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices consume significant power due to the use of batteries and IR protocols that require multiple pulses for each binary data transmission, leading to environmental pollution and inefficient energy use.
Innovation Solution
A remote control device that identifies binary codes based on a pre-set number of bit units, transmitting multiple bits as one pulse signal, with adjustable intervals and pulse widths to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional IR protocols use one pulse per binary data bit, then data transmission is simple and reliable, but power consumption is high
Solution Approach 1:
The patent merges multiple binary data bits into a single pulse signal by encoding groups of bits (e.g., 3 bits) into one pulse width variable. This consolidation reduces the total number of pulses transmitted, directly lowering power consumption while maintaining data integrity through the pulse width encoding scheme.
Solution Approach 2:
The patent changes the parameter representation by encoding multiple bits into pulse width variations rather than using separate pulses for each bit. By varying the width of single pulses to represent different bit combinations, the system reduces transmission pulse count and energy consumption while preserving all necessary data information.
2Duration of action of moving object
If multiple pulses are used for each binary data bit, then data transmission is reliable, but battery life is reduced
Solution Approach 1:
The patent combines multiple binary data bits into single pulse transmissions by encoding bit groups into pulse width variations. This merging approach reduces the frequency of pulse emissions, thereby extending battery life while maintaining complete data transmission through the encoded pulse width information.
Solution Approach 2:
The patent implements periodic pulse transmissions where groups of binary data bits are encoded and transmitted in structured intervals rather than continuous individual bit pulses. This periodic encoding and transmission pattern reduces overall energy loss by minimizing the number of active transmission events.
3Productivity
If one pulse represents one binary data bit, then transmission protocol is simple, but number of pulses required is large
Solution Approach 1:
The patent merges multiple binary data bits into single pulse signals by encoding groups of bits into pulse width variations. This consolidation increases data transmission efficiency by reducing the total pulse count required, thereby decreasing transmission time while maintaining protocol simplicity through the systematic pulse width encoding method.
