Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power generation elements are used to generate power for each button press, then the remote controller can operate without a battery, but the transmission delay of operation signals increases
Solution Approach 1:
The patent implements dynamic power source selection based on battery charge state. The system automatically switches between battery power and power generation element based on real-time battery residual quantity, optimizing both response time and operational autonomy. When battery charge is sufficient, battery power is used for immediate signal transmission; when battery charge is low, the system transitions to power generation mode.
Solution Approach 2:
The patent changes the power supply parameter (power source type) based on battery residual quantity thresholds. The control unit monitors battery charge levels and dynamically adjusts the power source configuration, switching between stored energy (battery) and generated energy (power generation element) to resolve the contradiction between immediate response and battery-free operation.
2Loss of time
If battery power is used for signal transmission, then transmission delay is reduced, but the battery will eventually deplete
Solution Approach 1:
The patent ensures continuous operational capability by maintaining both power sources (battery and power generation element) ready to serve. The system continuously monitors battery status and seamlessly transitions between power sources, ensuring uninterrupted operation. This dual-power architecture guarantees that the remote controller can always transmit signals without delay while extending overall operational duration through strategic power source management.
3Productivity
If the system switches between battery power and generated power, then both transmission speed and operational duration are improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal power management system where the control unit performs multiple functions: monitoring battery status, selecting power sources, managing signal transmission, and controlling the display unit. This multi-functional approach consolidates power management tasks into a single control unit, reducing overall system complexity despite the dual-power source architecture. The display unit also serves dual purposes by indicating both battery status and operational mode.

AI summary
An operation device includes an operation unit, a power generation element that generates power according to an operation of the operation unit, a battery that supplies power, and a communication unit that transmits an operation signal corresponding to the operation unit that has been operated. The communication unit transmits the operation signal by use of power supplied from the battery, in a case where a residual quantity of the battery is a predetermined residual quantity or larger. The communication unit transmits the operation signal by use of power generated by the power generation element, in a case where the residual quantity of the battery is smaller than the predetermined residual quantity.
