Solution Overview

Problem

Existing stop brackets for welding tables are not flexible enough to be fixed at any desired angle to the grid of holes on the tabletop and can be dimensionally unstable under heavy loads, which affects the precision of workpiece machining.

Innovation Solution

The angle element features two straight side walls that can be arranged at a predetermined angle to each other, with bores and an arc-shaped groove allowing for precise and flexible positioning and fixation using clamping bolts, and additional features like stiffening elements and cross braces enhance mechanical stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If known stop brackets are used to fix workpieces on welding tables, then workpiece fixing is enabled, but the brackets cannot be fixed flexibly at any desired angle to the grid of holes and require significant effort for positioning

Engineering Contradiction:
Improveflexibility of fixing angleVSAvoideffort required for fixing
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The angle element incorporates an arc-shaped groove that allows dynamic adjustment of the fixing angle. The clamping bolt can be positioned at any angle along the arcuate groove, enabling the angle element to be fixed at any desired orientation relative to the grid of holes without requiring significant positioning effort.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention introduces a rotational dimension through the arc-shaped groove, transforming the fixing mechanism from a fixed-angle bracket to a multi-angular angle element. This additional degree of freedom allows the bracket to be oriented at any angle while maintaining simple fixation through the clamping bolt system.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Strength

If known stop brackets are used, then workpiece fixing is enabled, but the brackets are dimensionally unstable under heavy loads causing side walls to move relative to one another

Engineering Contradiction:
Improvemechanical stabilityVSAvoidprecision of workpiece machining
Core Design Contradiction:
StrengthVSManufacturing precision

Solution Approach 1:

The arc-shaped groove is designed with a specific curvature radius that provides dimensional stability under heavy loads. The curved geometry distributes mechanical stresses more effectively, preventing the side walls from moving relative to one another while maintaining the required precision for workpiece machining.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The angle element is designed as a composite structure with strategically placed stiffening elements and cross braces that enhance mechanical stability. This composite design prevents deformation of the side walls under heavy loads, ensuring dimensional stability and machining precision.

Inventive Principle:
Principle #40Composite materials

3Reliability

If angle elements are fixed with multiple clamping bolts, then relative position and anti-rotation are achieved, but the fixing process becomes more complicated

Engineering Contradiction:
Improvefixing reliabilityVSAvoidcomplexity of fixing process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The fixing process is segmented into two distinct functions: the arc-shaped groove with its curvature radius provides the anti-rotation function, while the clamping bolts provide the positioning function. This segmentation allows the angle element to be fixed reliably with just one or two clamping bolts, simplifying the overall fixing process while maintaining high reliability.

Inventive Principle:
Principle #1Segmentation
