Handheld Mortise Forming Device with Rotatable Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mortise forming devices are limited in their ability to adjust and form various types of mortises, as they can only produce one specific type of mortise due to their fixed design, restricting versatility and user flexibility.
Innovation Solution
A handheld mortise forming device with a base unit, rotatable and slideable connecting units, and a clamping system that allows the user to switch between different working ends to cut various shapes and angles of mortises, including dovetail and vertical grooves, by using a combination of sliding tracks, pins, and nuts for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed design is used for mortise forming devices, then the device structure is simple, but the device can only form one specific type of mortise, reducing versatility
Solution Approach 1:
The pressing member is made rotatable relative to the base unit, allowing it to switch between different working ends (first working end for dovetail grooves, second working end for vertical grooves). This dynamic capability enables the device to form different types of mortises while maintaining a relatively simple overall structure.
Solution Approach 2:
The base unit is designed with multiple working ends on the pressing member, where each end serves a different function (forming dovetail grooves or vertical grooves). This multi-functionality allows a single device to perform multiple mortise forming operations without requiring separate specialized tools.
2Adaptability or versatility
If a fixed pressing member position is used, then the device structure is simple, but the device cannot accommodate different lumber thicknesses, reducing adaptability
Solution Approach 1:
The pressing member is designed to be rotatable and repositionable relative to the base unit through sliding tracks and connecting units. This dynamic positioning capability allows the pressing member to be adjusted to different positions according to lumber thickness requirements, enhancing the device's adaptability.

AI summary
A handheld mortise forming device includes a base unit having a first support extending parallel to a first axis. The first support includes first and second working ends. A first sidewall and a second sidewall are connected to the first support. One of two connecting units is rotatably mounted to the first sidewall. The other connecting unit is rotatably mounted to the second sidewall. A second support extends parallel to the first axis and is connected to the two connecting units. The second support is rotatable relative to the first and second sidewalls and includes an abutting face. A clamping unit includes a pressing member located on a side of the second support adjacent to the abutting face. The pressing member can clamp lumber. The pressing member is jointly rotatable with the second support and is switchable between the first working end and the second working end.
