Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformers, particularly those installed in wind-power facilities, face structural weaknesses due to high loads during operation and transportation, leading to potential disassembly and performance degradation, with conventional fixing systems failing to withstand extreme conditions.
Innovation Solution
A coil block fixation system featuring a geometrically coordinated supporting plate and coil block body with protrusions and recesses, combined with rods and spring elements, provides mechanical stability and shock resistance, allowing for stable operation under high acceleration shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing systems are used in transformers, then the structure is simple and easy to manufacture, but the transformer cannot withstand high loads and extreme acceleration shocks during operation and transportation
Solution Approach 1:
The fixation system is divided into multiple functional components: a coil block body with recesses, a supporting plate with protrusions, and multiple rods. This segmentation allows each component to perform its specific function while collectively providing enhanced reliability under high loads without excessive overall complexity.
Solution Approach 2:
The supporting plate with protrusions is nested within the recesses of the coil block body, creating an interlocking structure. The rods are then coupled to the supporting plate, forming a nested arrangement where each element fits within and supports the others, maximizing structural efficiency.
2Stability of the object's composition
If the supporting plate and coil block body are geometrically coordinated with protrusions and recesses, then translational and rotational movements are limited, but the manufacturing precision requirements increase
Solution Approach 1:
The supporting plate and coil block body feature asymmetric protrusions and recesses rather than symmetric features. This asymmetric design provides effective limitation of translational and rotational movements while being more tolerant to manufacturing variations compared to precision symmetric interfaces.
Solution Approach 2:
The rods act as intermediary elements between the supporting plate and the external loading structure. They transmit and distribute loads while allowing the protrusion-recess interface to focus specifically on limiting movements, thereby reducing the overall manufacturing precision requirements for the entire assembly.
3Strength
If rods are coupled to the supporting plate to set a load, then mechanical stability under acceleration shocks is improved, but the device complexity and number of components increase
Solution Approach 1:
The rods are merged with the supporting plate through direct coupling, creating an integrated load-bearing structure. This combining of elements provides enhanced mechanical stability under acceleration shocks while minimizing the number of separate components compared to using multiple independent fasteners or support structures.
Solution Approach 2:
The rods serve multiple functions: they couple the supporting plate to the external structure, distribute mechanical loads, and work in conjunction with the protrusion-recess features to limit movements. This multi-functionality reduces the need for additional specialized components, balancing strength requirements with device simplicity.

AI summary
A coil block fixation system (30) for a transformer comprises a coil block body to be coupled to a coil (19) of the transformer, and a supporting plate that is coupled to an upper surface (23) of the coil block body (10) opposite a bottom surface (24) of the coil block body (10). The coil block fixation system (30) further comprises two or more rods (3) that are coupled to an upper surface (21) of the supporting plate (1) opposite a bottom surface (22) of the supporting plate (1) for setting a load to the supporting plate (1) towards the coil block body (10). The supporting plate (1) and the coil block body (10) are formed geometrically in coordination with each other such that one comprise at least one recess (13, 14) and the other one comprise at least one protrusion (9, 16) that extends into the corresponding recess (13, 14) forming a respective movement limiter to counteract a translation and/or a rotation of the supporting plate (1) relative to the coil block body (10).
