Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable frames for oscillating saws lack an efficient mechanism to transition between storage and operative configurations, with existing designs often requiring complex and cumbersome operations to switch between parallel and perpendicular leg orientations.
Innovation Solution
A foldable frame design featuring a hinge with a vertically positioned axis, a spring-biased stop hook for closure, and tension bolt for fixation, along with running wheels and wedges for easy movement, allowing the support body sections to swivel 180° and the legs to pivot between storage and operative configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the legs are made swivelable between parallel and perpendicular configurations, then the frame achieves compact storage and extended operative use, but the mechanism for transitioning between configurations becomes complex and cumbersome
Solution Approach 1:
The support body is divided into two separable sections that can be connected or disconnected. This segmentation allows the frame to transition between configurations by simply connecting or disconnecting the sections, eliminating complex swiveling mechanisms while maintaining adaptability between compact and extended states
Solution Approach 2:
In the compact storage configuration, one support body section is inserted into or nested within the other section. This nesting approach achieves space reduction without requiring complex mechanical transitions, as the sections simply slide into each other for compact storage
2Ease of operation
If the support body sections are made separable for easy storage, then the frame achieves compact storage, but the structural stability during operative use may be compromised
Solution Approach 1:
The connection between support body sections is prepared in advance with pre-positioned connection elements and guiding features. This preliminary preparation ensures that when the sections are connected for operative use, they automatically align and lock into a stable configuration, maintaining structural integrity while preserving ease of assembly
Solution Approach 2:
The connection mechanism between support body sections is designed to self-align and self-lock when brought together. The sections automatically find their correct relative position and secure themselves without requiring precise manual alignment or additional fastening operations, ensuring both ease of operation and structural stability
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 design enhances ease of use and efficiency by allowing seamless transitions between configurations, enabling compact storage and extended operative use, with improved stability and ease of transport through integrated handles and securement mechanisms.
Implementation Method 1
The closure provides in particular a spring-biased stop hook
Implementation Method 2
The tension bolt is linked to one of the two hinge halves. In the restrained condition, the tension bolt extends through edge-open notches of both hinge halves
Implementation Method 3
On each free end of each support body section there is provided a running wheel

AI summary
The invention relates to a foldable frame (1) for oscillating saws or the like with an elongated support body (2), to which the oscillating saw is mountable, and to which, at each one of its two respective ends, are connected two legs (6,7), the latter being swivelable from a storage configuration in which they extend essentially parallel to the support body (2) to an operative configuration in which they extend essentially perpendicular from the support body (2). In order to improve the usefulness of the above-described foldable frame, it is proposed that the support body (2) be configured as two support body sections (3, 4), which are connected to one another by a hinge (5), which in the storage configuration lie parallel to each other, and which by swivelling movement through 180° can be brought into the operative configuration.
