Modular Outdoor Christmas Tree Frame With Integrated Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor Christmas tree assemblies are cumbersome, time-consuming, and expensive to assemble due to excessive electrical wirings and materials, lacking proper structural measures for safety and stability in outdoor weather conditions.
Innovation Solution
A cone-shaped frame made of detachable frustum-shaped segments with annular and lateral metal tubes, a harness cord system with socket outlets, and triangular reinforcing members for stability, along with interchangeable tree branches and lights, reduces material usage and simplifies assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional outdoor Christmas tree assemblies use excessive electrical wirings and materials to ensure safety, then safety requirements are met, but assembly becomes difficult, time-consuming and expensive
Solution Approach 1:
The Christmas tree assembly is divided into multiple detachable frame segments that can be easily connected and disconnected. Each segment contains pre-attached electrical components, allowing modular assembly that reduces overall complexity while maintaining safety through standardized connections
Solution Approach 2:
Electrical wirings are integrated directly into the frame structure rather than being separate components. The electrical sockets are built into the frame segments themselves, merging the structural and electrical functions into a single unified system that simplifies assembly
2Strength
If conventional outdoor Christmas tree assemblies use excessive materials to ensure structural strength, then safety requirements are met, but assembly becomes difficult, time-consuming and expensive
Solution Approach 1:
The frame is segmented into modular sections that can be assembled step-by-step. Each segment is designed with connection features that simplify assembly while maintaining overall structural integrity through the distributed framework design
Solution Approach 2:
The frame segments are designed with universal connection mechanisms that serve both structural and electrical functions. The same frame components provide both mechanical support and electrical conduit pathways, reducing the total number of parts needed
3Reliability
If conventional outdoor Christmas tree assemblies use traditional wiring systems, then electrical connections are established, but assembly becomes time-consuming and expensive
Solution Approach 1:
Electrical wiring is combined with the frame structure itself, eliminating separate wiring steps. The frame segments include built-in electrical pathways and pre-attached sockets, so that structural assembly automatically establishes electrical connections
Solution Approach 2:
Electrical components are pre-assembled and pre-wired into the frame segments during manufacturing. This preliminary preparation of electrical connections means that during on-site assembly, users only need to connect the frame segments themselves, and the electrical wiring is already in place

AI summary
An outdoor Christmas tree assembly includes a cone-shaped frame (10) formed of frustum-shaped frame segments (12, 14, 16, 18, 20, 22, 24) detachably stacked one on top of the other. Each frame segment includes annular frames (30) and slanted lateral frames (40). One or more frame segments are formed of end-to-end detachably connected arc-shaped frame sections. Tree branches (50) are detachably mounted on the annular frames. Each tree branch may include at least one set of lights, an electric socket, and an electric plug. A harness cord system (78) runs from top to bottom along a lateral side of the frame, and has socket outlets for electrically coupling to the electric plugs of the tree branches. Harness cords are secured to the frame by clamps (71). The frame may be supported on a base structure (200) having therein a working platform (250). The outdoor Christmas tree assembly is also applicable for indoor use.
