External Connection Modules Matched to Electrical Load Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection enclosures lack adaptability to various external electrical loads, resulting in oversized modules and inefficiencies due to a single type of external connection module being used regardless of the load, which limits size and modularity.
Innovation Solution
An electrical connection enclosure with a set of external connection modules, each adapted to specific power ranges (low, medium, high) with adjustable heights and reinforcement, allowing easy connection to electricity sources and protecting output connectors, ensuring optimal sizing and modularity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single type of external connection module is used regardless of the electrical load, then the module can be universally applied to different loads, but the module size becomes oversized and modularity is reduced
Solution Approach 1:
The external connection modules are segmented into multiple types based on power ranges (low power <11kW, medium power 11-30kW, high power 30-75kW). Each module type has specifically dimensioned cables or conductive busbars with cross-sections adapted to the electrical power consumed by the connected load, eliminating the need for oversized universal modules.
Solution Approach 2:
Each external connection module is designed with local quality characteristics matching its intended power range. The cables or conductive busbars have cross-sections specifically adapted to the electrical power requirements of the connected load, ensuring optimal sizing for each local application rather than using a uniform design for all loads.
2Adaptability or versatility
If external connection modules are customized for different power ranges, then adaptability to various loads improves, but the number of different module types increases
Solution Approach 1:
The external connection modules are differentiated by specific parameters (power range, cable cross-section, module height) rather than completely different designs. The set includes modules for low power (<11kW), medium power (11-30kW), and high power (30-75kW) ranges, with each parameter variation optimized for its specific application while maintaining overall system compatibility.
3Ease of operation
If the first end of external connection modules has a constant height equal to the base height, then connection to electricity sources is simplified, but the module design becomes more constrained
Solution Approach 1:
The first end of all external connection modules has a constant height equal to the height of the bases of all electricity sources, enabling a universal connection interface. This allows any module type (low, medium, or high power) to be connected to any electricity source without modification, simplifying installation while the rest of the module can be optimized for specific power ranges.

AI summary
An electrical connection enclosure comprises at least one electricity source connected to an associated electrical load and comprising a base, a frontal portion, a cover and functional elements attached to the base. All the electricity sources have a base of constant height and a frontal portion and a cover whose heights are adapted to the dimensions of the functional elements. The electrical enclosure comprises at least one external connection module (706) associated to one of the electricity sources and selected from a set of external connection modules. Each external connection module comprises a first end (709) of height equal to the height of the bases and comprising input connectors (710) connected to the electricity source, and a second end (711) of height equal to one, two or three times the height of the bases and less than or equal to the height of the associated electricity sources and comprising output connectors (712) connected to the electrical load.
