Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jig apparatus for forming channels in workpieces is often inaccurate and difficult to use, especially for amateur operators in confined spaces, and is not economically viable for forming small volumes of channels.
Innovation Solution
A portable apparatus with a drill assembly and actuation means that allows for guided and repeatable formation of channels, featuring a removable drill head, adjustable positioning, and a dust collection system, enabling accurate and efficient channel creation in workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a jig apparatus is used to form channels in workpieces, then the channels can be formed with guidance and positioning, but the apparatus becomes difficult to fit and position accurately on the workpiece
Solution Approach 1:
The jig apparatus is divided into separate modular components including a positioning block, a drill guide, and a clamping mechanism. These segments can be independently adjusted and positioned on the workpiece, making the apparatus easier to fit while maintaining channel positioning accuracy through the coordinated arrangement of the modular elements.
Solution Approach 2:
The jig apparatus incorporates adjustable and movable elements such as repositionable positioning blocks and adjustable drill guides that can be dynamically configured for different workpiece sizes and shapes. This dynamic adaptability allows accurate channel formation without requiring a fixed, complex apparatus design.
2Manufacturing precision
If more complex automatic or semi-automatic apparatus is used to retain the workpiece and perform drilling automatically, then the accuracy of channels formed is increased, but the apparatus becomes expensive and large in size
Solution Approach 1:
The apparatus incorporates a workpiece retention mechanism that uses the workpiece's own geometry and features to achieve self-positioning and self-retention during the drilling operation. This self-service approach eliminates the need for complex automatic retention systems while maintaining channel formation accuracy through the inherent stability of the workpiece-apparatus interface.
Solution Approach 2:
A simple intermediary positioning block serves as a mediator between the workpiece and the drill guide, transferring and maintaining the required positional relationship without requiring complex automatic control systems. This intermediary element provides the necessary accuracy through its geometric design rather than through automated mechanisms.
3Manufacturing precision
If complex automatic apparatus is used to form channels accurately, then channel accuracy is improved, but the apparatus is not suitable for domestic use and small volume production
Solution Approach 1:
The apparatus is designed with dynamic, adjustable components that can be reconfigured for different workpiece types and channel requirements. This adaptability allows the same apparatus to be used across various domestic and small-scale applications, making it versatile enough for amateur operators while maintaining accuracy through its adjustable positioning system.
Solution Approach 2:
The jig apparatus is designed as a universal tool that can accommodate multiple workpiece sizes, shapes, and channel configurations through its adjustable positioning blocks and drill guides. This multi-functionality allows a single apparatus to serve various domestic woodworking needs without requiring specialized equipment for each application.

AI summary
The invention relates to apparatus for the formation of a channel in a workpiece located at a first face of a base of the body of the apparatus, said channel formed by a drill assembly of the apparatus connected to drive means located on a second opposing side of the said base, said drill assembly and drive means mounted so as to be movable in a guided manner with respect to said base. The movement is achieved by manual movement of a gripping means of an actuation means of the apparatus with respect to said base, so as to cause one or more flexible connecting members of the actuation means which are positioned intermediate the said gripping means and drill assembly to move and advance the said drill assembly towards the said workpiece. The channel is formed in accurate manner which then allows the same to receive securing means typically to allow a joint between first and second workpieces to be accurately formed.
