Auxiliary Jigsaw Base Structure for Stable Tilted Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jigsaws have limitations in improving stability during cutting due to the retractable nature of known auxiliary bases, which restricts their size and effectiveness.
Innovation Solution
The introduction of an auxiliary base that can be attached to a jigsaw, featuring a contact portion that can be positioned farther in the direction of tilting than the center of gravity of the jigsaw, providing additional support and stability during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the auxiliary base is made retractable in a holder, then the base unit maintains a compact structure, but the stability of the jigsaw during cutting is insufficient
Solution Approach 1:
The auxiliary base is divided into a contact portion and a holder portion, which can be selectively positioned. The contact portion extends beyond the holder to provide additional stability without requiring the entire base structure to be complex or retractable.
Solution Approach 2:
The auxiliary base extends in the lateral direction beyond the base unit's width, utilizing the lateral dimension to improve stability. The contact portion protrudes laterally from the holder, creating a wider support footprint without increasing vertical or depth complexity.
2Stability of the object's composition
If the auxiliary base width is increased beyond the base unit width, then the stability during cutting is improved, but the device complexity increases
Solution Approach 1:
The auxiliary base is segmented into a holder portion that attaches to the base unit and a contact portion that extends outward. This segmentation allows the contact portion to be wider than the base unit without requiring the entire auxiliary base structure to be complex.
Solution Approach 2:
The holder portion of the auxiliary base is received within or alongside the base unit structure, while the contact portion extends outward. This nested arrangement allows the auxiliary base to provide extended width for stability while maintaining a compact overall form when not in use.

AI summary
An auxiliary base further improves the stability of a jigsaw during cutting as appropriate. An auxiliary base is attachable to a jigsaw. The jigsaw includes a base unit to be in contact with a workpiece, and a body tiltable relative to the base unit in a lateral direction. The auxiliary base includes a contact portion to be in contact with the workpiece when the auxiliary base is attached to the jigsaw. The auxiliary base is attachable with an auxiliary width from the contact portion to a middle of the base unit in the lateral direction of the body being greater than a width of the base unit in the lateral direction.
