Solution Overview

Problem

Existing power tools often require specific jigs, guides, and support tables that are not universally compatible, leading to frustration and underutilization when different tools are used in varying environments or limited spaces.

Innovation Solution

A modular apparatus with a frame and adjustable legs, allowing quick and efficient adaptation for multiple power tools, featuring interchangeable modules with common dimensions and engagement means for secure positioning, and adjustable surfaces for uniform work support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a table or bench apparatus is provided to accommodate a range of different power tool types, then the apparatus can be used with multiple power tools, but the apparatus requires extensive components and complex fitting arrangements that make it difficult to adapt for particular purposes

Engineering Contradiction:
Improvecompatibility with different power tool typesVSAvoidnumber of components and fitting arrangements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame is designed with a universal slot system that can accommodate multiple types of power tools through standardized module interfaces. The slot dimensions and engagement features are designed to work with various tool configurations, allowing one frame structure to serve multiple functions with different power tools.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The apparatus is divided into modular components including the frame, slots, and interchangeable modules that can be selectively engaged. This segmentation allows the system to be configured for different power tools by simply changing the module rather than redesigning the entire apparatus, reducing the complexity of fitting arrangements.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If apparatus is designed to accommodate multiple power tool types, then versatility is improved, but the time required to adapt the apparatus for a particular purpose increases

Engineering Contradiction:
Improveability to use different power toolsVSAvoidtime required to adapt apparatus
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The frame is pre-configured with slots and engagement features that are ready to receive specific modules. The modules are designed with pre-matched engagement mechanisms that align with the slot features, eliminating the need for complex fitting arrangements during adaptation and reducing the time required to switch between different power tool configurations.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If support legs are provided in extended position to hold the frame at a working distance, then the apparatus is stable for operation, but the apparatus cannot be stored efficiently in limited spaces

Engineering Contradiction:
Improvestability during power tool operationVSAvoidstorage space requirement
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The support legs are designed to be movable between an extended position during operation and a retracted position for storage. This dynamic configuration allows the apparatus to maintain stability when needed while minimizing its volume for storage in limited spaces, effectively adapting the apparatus's physical state based on operational requirements.

Inventive Principle:
Principle #15Dynamics

4Volume of moving object

If the top surface of the frame is positioned at a reduced distance from the support surface, then the apparatus occupies less space, but the gap between the frame and support surface becomes insufficient for proper operation

Engineering Contradiction:
Improvedistance from support surfaceVSAvoidadequacy of gap for power tool operation
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The movable support legs provide dynamic height adjustment, allowing the frame's top surface to be positioned at an optimal distance from the support surface during operation. This ensures adequate gap for power tool operation while still allowing the legs to be retracted when space minimization is required, balancing operational requirements with storage constraints.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to apparatus for use with one or a number of modules comprising a base with, or for the receipt of, a power tool. The module base is received in a recess, aperture or slot defined in a frame. Engagement means are provided to allow the module to be releasably engaged in position, guide means to allow the accurate introduction and removal of the module from the frame and the frame includes a plurality of support legs movable between a first extended position holding a top surface of the frame at a first distance from a support surface on which the legs are located, and a second position in which at least a portion of the legs are folded or retracted such that the said top surface is positioned with a gap at a reduced distance from the support surface.
