Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural attachments with foldable segments face challenges in assembly due to manufacturing tolerances, requiring precise alignment and additional steps like drilling and riveting, which are time-consuming and prone to slipping.
Innovation Solution
A pivot bearing holder with alignable support elements and frictional connections between segments, allowing for compensation of manufacturing tolerances and eliminating the need for additional positive connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If segments are connected by rigid positive connection elements (drilling and riveting), then assembly precision is improved, but assembly time and complexity increase
Solution Approach 1:
A pivot bearing holder is introduced as an intermediary component between segments. This holder includes alignable support elements that can be adjusted to compensate for manufacturing tolerances, eliminating the need for precise drilling and riveting while maintaining proper alignment during assembly
Solution Approach 2:
The pivot bearing holder is pre-configured with alignable support elements that establish the correct geometric relationship between segments before final assembly. This preliminary alignment structure prevents the need for time-consuming post-assembly adjustments or repositioning
2Stability of the object's composition
If support elements are rigidly connected, then structural stability is improved, but alignment flexibility during assembly deteriorates
Solution Approach 1:
The pivot bearing holder features support elements that are movable relative to each other during assembly, allowing dynamic adjustment to compensate for manufacturing tolerances. Once aligned, the elements are fixed to provide the necessary structural stability for operation
Solution Approach 2:
The geometric parameters of the support elements (such as their relative positions and orientations) can be changed during assembly to achieve proper alignment. After alignment is achieved, these parameters are fixed to maintain structural stability during use

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simplified assembly and alignment of segments, preventing slipping through frictional engagement, thus reducing assembly time and ensuring precise alignment without additional fastening steps.
Implementation Method 1
the friction element creates a frictional connection between the support elements of the pivot bearing bracket. The frictional connection prevents the support elements from slipping relative to one another
