Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If high-voltage windings are transported in an upright position, then mechanical stability is maintained during handling, but transportation profiles are exceeded and logistical costs increase
Solution Approach 1:
The device allows dynamic repositioning of the winding from vertical to horizontal orientation during transportation. The pillar-like element with movable retaining elements enables the winding to be securely held in either orientation, adapting to different transportation requirements without compromising mechanical stability.
Solution Approach 2:
The invention transitions the transportation orientation from vertical (exceeding profile limits) to horizontal (fitting within standard profiles). By rotating the winding 90 degrees around the pillar-like axis, the effective height is converted to length, allowing standard transportation while maintaining structural integrity through the fixing device.
2Length of stationary object
If high-voltage windings are transported horizontally, then transportation profiles are met, but mechanical stability is compromised leading to potential deformation
Solution Approach 1:
Before horizontal transportation, the winding is preliminarily secured to the pillar-like element using the retaining elements and spacing elements. This preliminary fixing action ensures that when the winding is positioned horizontally, it remains mechanically stable and resistant to deformation throughout the transportation process.
Solution Approach 2:
The pillar-like element acts as an intermediary between the winding and the transportation system. It provides a rigid structural framework that maintains the winding's shape and position during horizontal transportation, preventing direct contact with potentially damaging external forces while meeting transportation profile requirements.
3Productivity
If standard transportation profiles are used, then logistical efficiency is improved, but winding length is restricted
Solution Approach 1:
The device enables dynamic orientation change that allows longer windings to fit within standard transportation profiles. By switching from vertical to horizontal positioning, the effective dimension constrained by the profile is changed, permitting transportation of windings with greater actual length while maintaining logistical efficiency through standard transportation infrastructure.
