Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a charging station base is made as a prefabricated concrete part for easy installation, then installation simplicity is improved, but electrical connection complexity increases due to the need for cable routing through the concrete structure
Solution Approach 1:
The patent applies preliminary action by pre-forming recesses and channels in the concrete base during manufacturing. The cable recesses are created before installation, allowing cables to be easily routed through pre-prepared pathways in the concrete structure, eliminating the need for complex post-installation drilling or channel creation.
Solution Approach 2:
The patent uses the concrete base itself as an intermediary structure that contains integrated cable routing pathways. The recesses and channels act as intermediaries that guide and protect electrical cables from the ground level up to the charging station, simplifying the connection process while maintaining structural integrity.
2Stability of the object's composition
If the foot of the charging station base is enlarged to increase stability and prevent movement, then stability is improved, but the weight of the base increases making installation more difficult
Solution Approach 1:
The patent applies local quality by varying the cross-sectional dimensions of the foot along its height. The foot has a larger cross-section at the bottom for maximum stability and weight distribution, and a smaller cross-section at the top to reduce overall weight. This gradient design optimizes both stability and installability.
Solution Approach 2:
The patent uses parameter changes by modifying the geometric parameters of the foot structure. The foot's dimensions are optimized with specific length and width ratios (e.g., length 50-60 cm, width 30-40 cm) to achieve the desired balance between stability and weight, allowing the base to be firmly anchored while remaining manageable for installation.
3Ease of operation
If the charging station base is designed to be easily movable for installation, then ease of installation is improved, but stability and resistance to lateral forces deteriorate
Solution Approach 1:
The patent applies dynamics by designing the base with an optimized weight range (50-150 kg) that allows for controlled movement during installation using standard equipment, while providing sufficient mass to resist lateral forces and ensure stability during operation. The base transitions from being easily movable during installation to being firmly stable during use.
Solution Approach 2:
The patent uses preliminary action by incorporating installation holes and lifting features in the base design before installation. These pre-planned features enable easy positioning and anchoring during installation, after which the same structural elements contribute to the base's stability and resistance to lateral forces during operation.
4Shape
If the stump of the charging station base is enlarged to improve vertical alignment and visual impression, then visual quality is improved, but the amount of concrete material increases
Solution Approach 1:
The patent applies local quality by concentrating the stump's mass and dimensions specifically in the region that provides vertical alignment support, rather than uniformly increasing the entire base structure. The stump is dimensioned to provide sufficient visual presence and alignment function while minimizing excess material usage.

AI summary
The invention relates to a charging station base for an electrical charging station, comprising a foot (4) and a stump (6) projecting out of the foot (4). A simple installation and a high level of safety are guaranteed in that the foot (4) has a radial cavity (16) and the stump (6) has a opening (18) for accommodating an energy cable (28), which opening extends in the axial direction and is arranged above the cavity (16).
