Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid coupling mechanism is used to support the current transformer, then the current transformer is securely held in place, but the current transformer becomes vulnerable to damage from transportation, earthquake shock, and vibrations
Solution Approach 1:
The patent employs flexible position-limiting elements (including elastic elements and resilient members) that can deform and absorb mechanical shocks and vibrations, preventing damage to the current transformer while maintaining secure positioning. These flexible components act as shock absorbers during transportation and seismic events.
Solution Approach 2:
The patent incorporates cushioning elements and damping mechanisms that are pre-installed to absorb and dissipate impact energies before they reach the current transformer. The flexible position-limiting elements are designed to deform under shock loads, providing beforehand protection against damage from transportation, earthquakes, and vibrations.
2Strength
If additional fixing elements are used to secure the current transformer holder, then the holder is firmly attached, but the installation process becomes more labor-intensive and complex
Solution Approach 1:
The current transformer holder is designed with self-aligning and self-positioning features where the flexible position-limiting elements automatically adjust to fit the conductor and transformer geometry. The holder inserts into the transformer passage and the elastic elements deform to engage with the conductor, creating a secure attachment without requiring additional fixing elements or complex installation procedures.
Solution Approach 2:
The patent employs dynamic position-limiting elements that can deform and adapt during installation. The elastic and resilient members are designed to flex during insertion, then spring back to provide secure positioning, enabling easy installation while maintaining strong attachment strength.
3Manufacturing precision
If a rigid holder structure is used to maintain precise positioning, then the positional relationship is precisely maintained, but the holder becomes more complex and requires more manufacturing steps
Solution Approach 1:
The patent utilizes position-limiting elements with specific elastic moduli and geometric parameters that allow them to maintain precise positioning through their inherent elasticity. The flexible elements are designed with controlled stiffness characteristics that provide sufficient rigidity for positioning accuracy while remaining simple in structure and easy to manufacture.

AI summary
A current transformer holder includes a base, plural first position-limiting elements, plural second position-limiting elements, an opening and at least one guiding element. The base includes a first surface and a second surface opposite to each other. The first position-limiting elements are disposed on the first surface of the base for maintaining the current transformer holder in a passage of a current transformer. The second position-limiting elements are respectively disposed on the first position-limiting elements for defining a positional relationship between the current transformer holder and the current transformer. The opening is disposed on the base for being penetrated by the conductor so as to define a position of the conductor within the passage. The guiding element is disposed on the base at a position corresponding to the opening for guiding a direction of the conductor within the passage of the current transformer.
