Cordless Handset Power Saving Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless communication systems consume excessive power in standby mode due to continuous data exchange between base units and handsets, leading to increased energy consumption and reduced battery life.
Innovation Solution
Implementing a power-saving mode that interrupts power supply to wireless communication units in both base units and handsets, switching between normal and power-saving modes based on specific timers or commands, allowing for reduced power usage during idle periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base unit and handset periodically exchange data in standby state to maintain frequency synchronization, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the operational state of the wireless communication unit between standby mode (power-saving) and normal mode (active communication). The switching unit enables the system to transition between these states based on communication needs, allowing the base unit and handset to periodically wake up and exchange synchronization data only when necessary, rather than maintaining continuous operation.
Solution Approach 2:
The patent implements periodic data exchange between the base unit and handset in standby state to maintain frequency synchronization. The base unit periodically transmits data to the handset, and the handset periodically receives and responds with data. This periodic action ensures communication reliability is maintained while minimizing power consumption by keeping the wireless communication unit in a low-power state between these periodic exchanges.
2Speed
If the wireless communication unit operates continuously in normal mode, then communication responsiveness is improved, but power consumption increases
Solution Approach 1:
The system dynamically switches between power-saving mode and normal mode based on communication requirements. When communication is needed, the switching unit activates the wireless communication unit, enabling immediate response. When idle, the unit remains inactive to conserve power. This dynamic state change allows the system to achieve high responsiveness when needed while maintaining low power consumption during idle periods.
Solution Approach 2:
The base unit and handset automatically manage their own power states through the switching unit. The system self-adjusts by determining when to wake from power-saving mode and when to remain inactive, based on internal timers and communication protocols. This self-service mechanism eliminates the need for external power management while optimizing both responsiveness and power consumption.

AI summary
A cordless communication system includes a base unit and a handset. The base unit is connectable to a communication line. The handset includes a handset wireless communicating unit, a handset communicating unit, a handset switching unit, and a handset starting unit. The handset wireless communicating unit implements wireless communications with the base unit wireless communicating unit. The handset communicating unit is capable of communicating signals with the base unit. The handset switching unit switches between a handset normal mode in which power is supplied to the handset wireless communicating unit and a handset power-saving mode in which power to the handset wireless communicating unit is interrupted. The handset starting unit controls the handset switching unit to supply power to the handset wireless communicating unit in order to switch to the handset normal mode from the handset power-saving mode if the handset communicating unit receives a handset start signal instructing the handset to cancel the handset power-saving mode during the handset power-saving mode.
