Timber Support End Protection via Non-Penetrating Caps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wooden beams for construction, used in formwork for concrete structures, suffer from end damage due to improper handling and impact, with previous protection methods like caps or plastic coatings failing to prevent splintering and embrittlement.
Innovation Solution
The wooden beam features belt end protective caps made of resistant materials like metallic galvanized sheet metal, fastened to the connecting element's side flanks using secure fastening means, which prevent weakening of the wood and enhance shock resistance, while also being resistant to UV light and impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If caps are slipped onto the ends of the belt and fastened by means of tubular rivets, then the belt ends are protected from damage, but the attachment damages the wood of the strap itself, increasing its tendency to splinter
Solution Approach 1:
The patent introduces a protective cap as an intermediary element between the impact source and the wooden belt end. The cap is fastened to the belt end using fastening means that do not penetrate the wood, thereby protecting the wood from direct impact while still providing protection against damage.
Solution Approach 2:
The patent changes the fastening method from penetrating rivets to non-penetrating fastening means (such as clips or bands) that apply force without damaging the wood structure. This parameter change in the fastening mechanism preserves the wood's integrity and shock resistance while still providing end protection.
2Strength
If plastic coating is used to protect belt ends, then the wood structure is not weakened, but plastic is subject to aging processes that lead to embrittlement and the cap breaks under high load
Solution Approach 1:
The patent employs composite material construction by combining the protective cap (made of UV-resistant material) with the wooden belt end through a non-damaging fastening system. This composite approach allows the cap to provide protection against UV radiation and impact while the wood structure maintains its shock resistance properties.
Solution Approach 2:
The patent changes the material properties of the protective cap by selecting materials that are resistant to UV radiation and embrittlement. This parameter change in material selection ensures long-term durability and reliability under various environmental conditions and impact loads.
3Ease of operation
If the wooden beam is dragged on concrete surface for transport, then the beam can be moved, but the ends can easily rub off and damage occurs
Solution Approach 1:
The patent applies protective caps to the belt ends before transport and handling operations. These caps serve as a cushioning layer that prevents direct contact between the wooden ends and the concrete surface, thereby reducing friction damage and wear during transport while maintaining ease of movement.
