Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnets are fixed to the base via rivets, then the tool holding frame can be magnetically fixed to the bracket, but the assembly process becomes tedious and manufacturing cost increases
Solution Approach 1:
The magnetic plate is integrated directly into the base as a single piece structure, eliminating the need for separate riveting operations. The base and magnetic plate form an integrated component that is directly attachable to the bracket, combining multiple parts into one to simplify assembly while maintaining magnetic fixation reliability.
2Manufacturing precision
If the connecting portion has a through hole with abutting buckle and spring, then the tool part can be positioned, but the assembly becomes inconvenient and manufacturing cost increases
Solution Approach 1:
The abutting buckle and spring components are removed from the connecting portion structure. Instead of using a through hole with separate positioning components, the invention uses a simple slot structure that provides tool part positioning through its geometry alone, eliminating unnecessary components and simplifying the overall structure while maintaining positioning precision.
3Reliability
If multiple components are used for magnet fixation and tool positioning, then functional requirements are met, but assembly time and manufacturing cost increase
Solution Approach 1:
Multiple functional components are merged into integrated structures: the magnetic plate is integrated with the base, and the slot structure integrates positioning and guiding functions. This reduction in component count directly decreases assembly time while maintaining or improving fixation reliability through the simplified, more robust integrated design.

AI summary
A tool holding frame has a base and at least one connecting part. The base has a body, a rail, and a magnetic plate. The body has a top, a bottom opposite to the top of the body, an assembling recess formed in the bottom of the body, and multiple positioning pillars protruding inside the assembling recess. The rail is disposed at the top of the body. The magnetic plate is fixed in the assembling recess in an interference fit and has multiple positioning holes respectively disposed on and around the multiple positioning pillars. Each positioning hole is fixed to a corresponding one of the positioning pillars in an interference fit. Each connecting part has a connecting portion and two clamping portions respectively formed at two opposite sides of the connecting portion and respectively engaging with two opposite sides of the rail.
