Solution Overview

Problem

Existing locker and cabinet systems with limited access, such as post office boxes, face challenges in ensuring secure and easy use while providing clear information about locker status and accessibility, often requiring complex constructions and additional power sources for lighting elements.

Innovation Solution

A door design for lockers or cabinets with integrated light beam transmitting surfaces and lighting elements, allowing visual indication of locker status and position, which are powered by the control module without needing separate batteries, using a simple construction that facilitates manufacturing and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If lighting elements are installed in lockers to indicate status and position, then visibility and information provision are improved, but device complexity and power requirements increase

Engineering Contradiction:
Improvelocker status informationVSAvoidlighting system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the lighting element with the door structure itself, integrating the light source into the door panel rather than using separate lighting components. This merging reduces device complexity while maintaining the information provision function, as the door serves dual purposes: structural closure and light emission for status indication.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The door is designed to serve multiple functions: it acts as both the closure element and the lighting element. The door panel incorporates light-transmitting properties, allowing it to function as both a structural component and an information display medium, thereby reducing overall system complexity while providing necessary visual cues about locker status.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If separate battery power sources are used for lighting elements, then lighting reliability is improved, but device complexity and maintenance requirements increase

Engineering Contradiction:
Improvelighting reliabilityVSAvoidpower system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the power supply for the lighting element with the existing control module that already powers the lock mechanism. By drawing power from the same source that operates the locking system, the design eliminates separate battery requirements, reducing device complexity and maintenance needs while ensuring reliable operation through the established power infrastructure.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of information

If complex constructions are used to provide lighting and information display, then information visibility is improved, but manufacturing and assembly difficulty increase

Engineering Contradiction:
Improvestatus information visibilityVSAvoiddoor manufacturing ease
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The patent integrates the light-transmitting function directly into the door panel construction, using materials or structures that inherently allow light passage. This approach eliminates the need for separate lighting housings, lenses, or complex optical assemblies, thereby simplifying manufacturing and assembly processes while effectively conveying status information through the door itself.

Inventive Principle:
Principle #5Merging (Combining)
