Holiday Tree Stand Venting for Passive Heat Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Holiday lighting systems, particularly artificial tree lighting, face challenges with heat management, leading to potential damage, smoke, and fires due to inefficient power conversion and conditioning from AC to DC power, which existing technologies have not adequately addressed.
Innovation Solution
A heat pump tree stand (HPTS) that actively dissipates heat through venting, radiation, and conduction without moving parts, noise, or a power source, incorporating a housing with directional upper vents and a heat pump riser to efficiently remove and disperse heat generated by electrical components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical components for power conversion and conditioning are added to the tree stand, then the functionality and safety of the lighting system is improved, but heat generation increases causing potential damage and fire hazards
Solution Approach 1:
The patent extracts the harmful heat generated by electrical components and removes it from the housing through dedicated heat removal structures. The heat is channeled outward through thermal conduction paths and convection vents, separating the heat source from the sensitive electrical components and preventing fire hazards while maintaining the beneficial power conversion functionality.
Solution Approach 2:
The patent introduces thermal management structures as intermediary elements between the heat-generating electrical components and the surrounding environment. These intermediaries include heat sinks, thermal conduction paths, and convection vents that mediate the heat transfer process, allowing heat to be safely dissipated without directly exposing electrical components to dangerous temperatures.
2Reliability
If the housing is sealed for safety, then protection of electrical components is improved, but heat dissipation becomes difficult
Solution Approach 1:
The patent applies local quality by creating differentiated zones within the housing: sealed enclosed spaces for protecting electrical components from external hazards, and localized thermal escape pathways for heat dissipation. The housing structure has different properties in different locations - sealed walls for protection and vented/thermally-conductive regions for heat removal.
Solution Approach 2:
The patent converts the harmful trapped heat into a manageable thermal flow by designing controlled convection pathways. The heat that would otherwise be a hazard is redirected through designated channels and vents, transforming from a dangerous byproduct into a controlled thermal management system that maintains component protection while enabling dissipation.
3Temperature
If traditional heat removal methods using fans or motors are used, then heat dissipation efficiency is improved, but device complexity and potential failure points increase
Solution Approach 1:
The patent implements self-service heat removal by designing passive thermal management structures that automatically dissipate heat without external control or power input. The convection vents and thermal conduction paths self-regulate based on temperature gradients, with hot air naturally rising and exiting through vents while cooler air replaces it, creating a self-sustaining heat dissipation cycle.
Solution Approach 2:
The patent replaces mechanical heat removal systems (fans, motors, pumps) with passive thermal management structures. Instead of using mechanical forces to move air or coolant, the system relies on natural convection, thermal conduction, and radiation - fundamental thermal physics mechanisms that require no moving parts or external power sources.

AI summary
A tree stand includes a housing dimensioned for holding electronic components used in providing electricity in support of decorative lighting for the tree. The tree stand removes heat from the housing without the use moving parts. Floor vents enable cool air to enter the housing; upper vents enable that air, warmed by the electrical components, to escape to the housing and into a heat riser housing as part of a growing, circular heat thermal. The heat follows a spiral ramp in the heat riser housing exiting vents at the top where additional heat is conducted into the tree itself, radiated into the air. Tree legs can be increased in number or replaced with longer legged trees without tools by insertion of the side wall into a slot formed in the legs and then slid around the circular slide wall from the notch where each leg is inserted.
