Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective coverings fail to address the puncture and laceration hazards posed by exposed masonry straps and similar hardware elements, lacking a suitable design to fit and provide strength and rigidity.
Innovation Solution
A protective cap with a corrugated sleeve and base, featuring a slot for fitting over the hardware end, enhancing strength and rigidity, and a tapered perimeter to deflect impacts, made from materials like polyurethane or polyvinyl chloride, with optional safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective covering is applied to cover exposed masonry straps, then puncture and laceration hazards are prevented, but the covering must provide sufficient strength and rigidity to resist impacts
Solution Approach 1:
The patent employs a corrugated sleeve structure that uses a flexible yet rigid material to provide protective coverage. The corrugated design allows the material to maintain flexibility while achieving the necessary rigidity through its geometric configuration, effectively preventing punctures and lacerations without requiring excessive material thickness or strength.
Solution Approach 2:
The protective covering is constructed from composite materials that combine different properties to achieve both protection and structural integrity. The use of corrugated material provides a composite structure that delivers enhanced strength and rigidity while maintaining the ability to conform to the hardware element being protected.
2Strength
If a corrugated sleeve structure is used to improve strength and rigidity, then the protective covering can resist impacts, but the complexity of the structure increases
Solution Approach 1:
The corrugated sleeve utilizes a curved, wave-like structure that naturally distributes impact forces across its surface. This geometric curvature provides enhanced strength and rigidity without requiring additional reinforcement elements or complex assembly mechanisms, thereby maintaining structural simplicity while achieving the desired mechanical properties.
3Adaptability or versatility
If the sleeve has a slot open at the top end to fit around hardware, then the covering can be applied to various hardware elements, but the opening may allow debris or water entry
Solution Approach 1:
The slot design at the top end of the sleeve provides universal adaptability, allowing the protective covering to fit around various hardware elements such as masonry straps, rebar, and T-posts. The standardized slot configuration enables the same protective structure to serve multiple functions and protect different types of hardware without requiring custom designs for each application.

AI summary
A cap apparatus for preventing punctures and lacerations caused by exposed sheet metal hardware includes a base and a sleeve which are coupled together. The sleeve has a front wall, a back wall, and a pair of lateral walls and has a slot surrounded by the same. The slot is sized such that the sleeve fits around an exposed end of an article of hardware. The front wall and the back wall are corrugated, and inner portions of the front wall and the back wall define an envelope which contains the exposed end of the article of hardware when the cap apparatus is placed over the article of hardware. The envelope has a rectangular cross section.
