Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playground equipment bearing members, particularly metal and wooden posts, face issues such as temperature conductivity, decay, corrosion, and cost limitations, posing safety and production challenges.
Innovation Solution
The use of galvanized metal posts with a composite siding material featuring reinforcing cells and a modular design, which includes wood, plastics, or derivatives, providing a robust, corrosion-resistant, and cost-effective solution by eliminating the need for welding and allowing for adjustable lengths and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal posts are used for bearing members, then mechanical strength and formability are improved, but thermal conductivity causes cold contact effects and temperature sensitivity
Solution Approach 1:
The patent applies composite materials by combining metal posts with wooden profile coverings. The metal post provides mechanical strength while the wooden covering reduces thermal conductivity to eliminate cold contact effects. This composite structure resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The wooden profile acts as an intermediary layer between the metal post and human contact. It mediates the thermal interaction by providing a warm surface that contacts users, while the metal post remains hidden and provides structural support without direct contact.
2Object-affected harmful factors
If wooden posts are used for bearing members, then thermal conductivity is reduced eliminating cold contact effects, but decay occurs upon contact with soil moisture
Solution Approach 1:
The patent segments the post into two functional parts: the lower portion embedded in ground (metal, decay-resistant) and the upper portion for user contact (wooden profile, thermally comfortable). This segmentation allows each material to perform optimally in its specific environment.
Solution Approach 2:
The composite structure combines metal and wood in a functional division where metal provides decay resistance in the ground-contact zone while wood provides thermal comfort in the user-contact zone, resolving both contradictions simultaneously.
3Stability of the object's composition
If cylindrical wooden posts are used in single pieces for desired lengths, then material continuity is improved, but production costs increase significantly
Solution Approach 1:
The patent segments the wooden profile into modular sections with standardized lengths that can be manufactured economically and assembled on-site. This segmentation reduces production costs while the connection channels maintain structural continuity.
Solution Approach 2:
The universal connection channel design allows standardized wooden sections to be assembled into various lengths and configurations. This multi-functional modular system enables cost-effective production of posts in nearly desired lengths through simple assembly rather than expensive custom manufacturing.
4Stability of the object's composition
If wooden posts are inserted into ground for stability, then structural stability is improved, but decay occurs upon contact with soil moisture
Solution Approach 1:
The patent segments the post system into ground-embedded metal portions and above-ground wooden portions. The metal segments provide decay resistance in the moisture-exposed ground zone while maintaining structural stability, and the wooden segments provide user-friendly surfaces above ground where decay is not an issue.
