Bevel Locking System with Lateral Lever for Saw Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bevel locking systems in saw apparatuses often have handles located on rear sides, making them difficult to access and manipulate, and those on front or lateral sides are complicated by the presence of brake pads and other hardware, leading to operational drawbacks.
Innovation Solution
A bevel locking system comprising a bevel pin, spring, locking arm, and lever that allows for easy transition between unlocked and locked states, with the lever being movable between an unlocked and locked position to clamp or release the table assembly relative to the bevel post, facilitating access and reducing the need for additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the handle is located on the rear side of the saw apparatus, then the locking mechanism can be integrated with the cutting assembly, but the handle becomes difficult to access and manipulate
Solution Approach 1:
The handle is repositioned from the rear side to the lateral side of the saw apparatus, changing its spatial dimension. This lateral positioning allows the handle to be easily accessible while maintaining integration with the cutting assembly through the bevel locking mechanism, resolving the contradiction between integration and accessibility.
2Ease of operation
If the handle is located on the front or lateral side of the saw apparatus, then the handle is easily accessible, but brake pads and other hardware devices are required
Solution Approach 1:
The brake pads and other additional hardware components are removed from the system. The invention achieves the desired handle accessibility on the lateral side by using a simplified bevel locking mechanism with spring-loaded engagement, eliminating the need for complex braking systems while maintaining operational effectiveness.
Solution Approach 2:
The spring-loaded bevel locking mechanism automatically engages and disengages the locking arms without requiring additional braking hardware. The spring force provides the necessary locking and releasing action, making the system self-sufficient and eliminating dependence on external brake pads or complex hardware devices.
3Device complexity
If a spring-loaded bevel locking mechanism is used, then the locking and releasing action is simplified, but the spring force must be sufficient to maintain secure locking
Solution Approach 1:
Multiple locking arms are combined with a single spring mechanism, merging the locking and releasing functions into one integrated system. This allows the spring force to be distributed across multiple locking points, maintaining sufficient locking strength while keeping the mechanism simple and easy to operate.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides easy access and manipulation of the bevel locking mechanism, eliminating the need for rear-mounted handles and reducing complexity, thereby enhancing usability and cost-effectiveness by eliminating the requirement for brake pads and other hardware.
Implementation Method 1
The spring is configured to bias a movement of the bevel pin
Implementation Method 2
The lever is movable between an unlocked position and a locked position

AI summary
An apparatus includes a table assembly, a bevel post, a bevel pin, a spring, a locking arm, and a lever. The table assembly includes a table portion with a work surface and a hub portion with a first clamping surface. The bevel post includes a second clamping surface. The bevel pin pivotally connects the bevel post to the hub portion. The spring is configured to bias a movement of the bevel pin. The locking arm is configured to (i) disengage the spring such that the bevel pin releases the table assembly from the bevel post and (ii) engage the spring such that the bevel pin moves the table assembly towards the bevel post. The lever is movable between an unlocked position to provide an unclamped state and a locked position to provide a clamped state with respect to the first and second clamping surfaces.
