Solution Overview

Problem

Electronic access control systems in battery-operated parcel boxes have high energy consumption, which is a disadvantage as they must be constantly ready to grant access, and there is no connection to the power grid.

Innovation Solution

A method and device that detects the presence of an access authorization verification device using first communication means to change the operating mode of second communication means, allowing energy-saving modes for the access control system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the access control system uses electronic communication means to detect presence and maintain readiness to grant access, then access control functionality is ensured, but energy consumption increases

Engineering Contradiction:

Improveaccess control readinessVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The communication means dynamically changes its operating mode based on detected presence. When no presence is detected, the system operates in a low-power mode. When presence is detected via the first communication means, the system transitions to a higher-power mode for the second communication means to handle access authorization, thus adapting power consumption to actual operational needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses periodic detection cycles with the first communication means to monitor for presence. The communication means operates intermittently rather than continuously, switching between active detection phases and low-power standby phases, reducing overall energy consumption while maintaining access control readiness

Inventive Principle:

Principle #19Periodic action

2Adaptability or versatility

If the access control system uses battery power without grid connection, then installation flexibility is improved, but energy availability is limited

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidenergy availability

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The communication system is segmented into two distinct communication means with different power consumption characteristics. The first communication means operates continuously at low power for presence detection, while the second communication means operates only when needed at higher power levels, dividing the communication function to optimize battery usage

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes operational parameters of the communication means based on detected conditions. When presence is detected, the system adjusts power output and communication activity parameters upward; when absent, parameters are reduced to minimal levels, optimizing energy availability for battery operation

Inventive Principle:

Principle #35Parameter changes
