Jigsaw Plunger Support Structure With Integrated Rocking and Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reciprocating tools, such as jigsaws, have complex structures with multiple parts due to separate mechanisms for rockably and movably supporting the plunger and tip tool, increasing the number of components and complexity.
Innovation Solution
A reciprocating tool design where the connector member serves as both a mechanism for rockably and movably supporting the plunger, reducing the number of parts by integrating these functions into a single component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mechanisms are used for rockably supporting the plunger and movably supporting the plunger along the axis, then the plunger can be properly supported with both rocking and linear movement capabilities, but the number of parts increases and the structure becomes complex
Solution Approach 1:
The connector member integrates two separate support functions into a single component: it provides both rockable support (via the rocking mechanism with support pin) and movable support along the axis (via guide members with grooves). This merging eliminates the need for separate mechanisms, reducing part count while maintaining both support capabilities.
Solution Approach 2:
The connector member serves multiple functions simultaneously: it connects the power transmission mechanism to the plunger, enables rocking motion through the support pin, guides linear movement through the grooves, and supports the plunger in both rocking and linear directions. This multi-functionality resolves the contradiction by consolidating support mechanisms.
2Reliability
If multiple separate components are used to support the plunger for rocking and linear movement, then proper mechanical support is achieved, but the number of parts increases
Solution Approach 1:
The connector member combines multiple support functions into one component, eliminating the need for separate rockable support mechanisms and linear movement guides. This single component provides both rocking support via the support pin and linear guidance via integrated grooves, significantly reducing the total number of parts.
Solution Approach 2:
The connector member is designed as a multi-functional component that simultaneously provides rockable support, linear movement guidance, and mechanical connection. This universality allows one part to perform the work of multiple separate components, reducing part quantity while maintaining mechanical support reliability.

AI summary
A reciprocating tool with a reduced number of parts is provided. A jigsaw 11 reciprocates a saw blade 32 in a direction along an axis C1 with the power of an electric motor. The jigsaw 11 includes a housing 12 accommodating the electric motor, a guide member 40 fixed to the housing 12 and provided along the axis C1, a connector member 33 sandwiching the guide member 40 and reciprocating when the power of the electric motor is transmitted thereto, and a plunger 31 attached to the connector member 33 and holding the saw blade 32.
