Solution Overview

Problem

Current luminaire designs face challenges in reliable signal reception due to conductive housing materials like aluminum or brass, limiting the range of Bluetooth or Wi-Fi control, and external antennas are prone to damage and increase costs.

Innovation Solution

The antenna is relocated within a non-conductive knuckle assembly at the base of the luminaire, allowing signal transmission through a non-conductive material, enhancing reception and reducing the risk of damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the antenna is placed on the driver board within the luminaire housing, then the device complexity is reduced, but the signal reception reliability deteriorates due to interference from conductive housing materials

Engineering Contradiction:

Improveantenna placement simplicityVSAvoidsignal reception reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The luminaire is divided into separate functional zones: the driver board remains inside the conductive housing for electrical functions, while the antenna is segmented and placed in a separate non-conductive knuckle assembly for wireless communication functions. This spatial segmentation allows each component to operate in its optimal environment without interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The non-conductive knuckle assembly acts as an intermediary structure that houses the antenna. This intermediary provides a signal-friendly environment for the antenna while maintaining the structural integrity and electrical functionality of the conductive housing, effectively mediating between the conflicting requirements of electrical shielding and wireless signal reception.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If an external antenna is used on the luminaire, then the signal reception reliability improves, but the device is more susceptible to damage from environmental factors and mechanical equipment

Engineering Contradiction:

Improvesignal reception reliabilityVSAvoidmechanical damage and environmental exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The antenna is nested within the knuckle assembly, which itself is part of the luminaire's structural housing. This nested configuration protects the antenna from external mechanical damage and environmental factors while maintaining its signal reception capabilities. The antenna is effectively sheltered within the existing structural envelope of the luminaire.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The knuckle assembly, which provides structural support and mechanical connection to the housing, is repurposed to also provide protective shielding for the antenna. The same structural elements that could potentially transmit mechanical stress are converted into a protective barrier that shields the antenna from external hazards while maintaining signal transmission.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If an external antenna is attached to the luminaire, then the signal reception range is extended, but the manufacturing cost increases

Engineering Contradiction:

Improvesignal reception rangeVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The knuckle assembly is designed to serve multiple functions: it provides structural support for the luminaire, acts as a mechanical connector between the housing and ground stake, and simultaneously serves as a protective housing for the antenna. This multi-functionality eliminates the need for separate antenna mounts or additional structural components, reducing manufacturing costs while maintaining extended signal reception capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The antenna housing function is merged with the existing knuckle assembly structure. Instead of adding a separate antenna mount or external antenna housing, the design combines the antenna enclosure with the knuckle assembly that already exists as part of the luminaire's structural framework, thereby avoiding additional manufacturing costs while achieving the required signal reception performance.

Inventive Principle:

Principle #5Merging (Combining)
