Disposable Threshold Cover with Hooked Tip for Construction Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing threshold protective covers for building entryways during construction are either costly or lack adequate protection, leading to damage from heavy traffic and substances like paint and mortar, necessitating an improved, cost-effective solution for temporary protection.
Innovation Solution
A removable protective cover system comprising a cap protecting member with a hooked tip and a deck protecting member, designed to fit over the threshold cap and sill deck, respectively, made from thin plastic extrusions like rigid vinyl, ensuring easy installation and removal to maintain the entryway's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective covers are used to protect threshold components during construction, then protection effectiveness is improved, but material costs increase
Solution Approach 1:
The protective cover is designed as a disposable, low-cost item made from thin plastic extrusion material. It provides adequate protection during construction but is intended to be discarded rather than reused, eliminating the need for expensive durable protective covers while maintaining sufficient protection effectiveness during the construction period.
Solution Approach 2:
The protective cover utilizes thin plastic extrusion material that forms a flexible yet protective shell over the threshold components. This thin film approach provides adequate protection against construction damage without requiring thick, expensive materials, thus reducing material costs while maintaining protection effectiveness.
2Reliability
If protective covers are made from durable materials, then protection effectiveness is improved, but ease of manufacture worsens
Solution Approach 1:
The protective cover is manufactured from thin plastic extrusion material, which is far easier to work with than durable materials like metal or thick plastic. The thin film nature allows for simple extrusion manufacturing processes, easy cutting to size, and straightforward installation, significantly improving ease of manufacture while still providing adequate protection during construction.
Solution Approach 2:
By accepting that the protective cover is disposable rather than durable, the invention can use simpler, easier-to-manufacture thin plastic materials instead of requiring complex manufacturing processes needed for durable materials. This disposable approach allows for simpler extrusion and forming processes.

AI summary
A cover for removable protection of a threshold is disclosed. The threshold may be of the type having a sill deck terminating in an upwardly extending dam and a threshold cap disposed along an interior side of the dam. The cover has at least a cap protecting member configured to extend over the threshold cap of the threshold. The cap protecting member includes an engagement portion configured to be positioned along an exterior side of the dam. The engagement portion has a hooked tip. Upon completion of construction, the cover is designed to be removed from the threshold to expose at least the threshold cap below.
