Actuated Blade Guard Assembly for Safe Saw House Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saw house systems lack a reliable and safe method to protect operators from exposed circular saw blades during maintenance and access, as they require special protective equipment and automated systems for grinder setup and cleaning, which are prone to errors and harsh environments.
Innovation Solution
A blade guard assembly with a blade cover and actuator that positions the cover over the saw blade to prevent exposure during maintenance and access, allowing safe entry without special equipment, and includes a maintenance blade carrier for handling saw blades, with sensors and interlocks to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the saw blade is exposed for maintenance and access, then operators can perform maintenance activities, but operators are at risk of injury from the exposed cutting edge
Solution Approach 1:
A blade carrier is introduced as an intermediary device between the operator and the saw blade. The blade carrier includes a blade cover that can be positioned over the cutting edge to provide protection, while still allowing the blade to be accessed for maintenance activities when needed.
Solution Approach 2:
The blade cover is designed to be movable between different positions - covering the cutting edge when protection is needed and being removable or movable away when maintenance access is required. This dynamic positioning allows the system to adapt between safety and accessibility states.
2Object-affected harmful factors
If special protective equipment and automated systems are used for grinder setup and cleaning, then operator safety is improved, but system complexity and cost increase
Solution Approach 1:
The blade carrier system is designed to be manually operated by the operator without requiring complex automated systems. The operator can manually position the blade cover and use the blade carrier for maintenance activities, eliminating the need for expensive and complex automated protective systems while still providing adequate safety.

AI summary
A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.
