Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional adjustment mechanisms are used, then the circuit breaker can be positioned, but the adjustment is limited and non-continuous, leading to potential misalignment
Solution Approach 1:
The patent transforms the static, fixed-position adjustment mechanism into a dynamic, continuous adjustment system. The threaded rod allows the circuit breaker to be positioned at any point along its travel path, enabling fine-tuned alignment rather than being constrained to discrete positions. This dynamic adjustment capability simultaneously improves positioning precision and extends the effective adjustment range.
Solution Approach 2:
The invention changes the adjustment parameter from discrete, limited steps to continuous variable positioning through the threaded rod mechanism. By rotating the threaded rod, the circuit breaker can be moved incrementally along the entire length of the rod, providing continuous adjustment of the positioning parameter rather than fixed incremental steps.
2Reliability
If fixed positioning is used, then the circuit breaker is stable, but inadvertent positional changes can occur over time or with movement
Solution Approach 1:
The patent incorporates preliminary positioning action during the adjustment process. The threaded rod mechanism allows operators to pre-adjust the circuit breaker to the exact desired position before final tightening, ensuring proper alignment is established in advance. This preliminary precise positioning prevents subsequent misalignment and maintains position stability over time.
Solution Approach 2:
The invention replaces simple mechanical fastening with a threaded mechanical adjustment system. The threaded rod provides both adjustment capability and locking function, substituting for more complex adjustment mechanisms while maintaining position stability through the self-locking nature of threaded fasteners.
3Ease of operation
If limited adjustment mechanisms are used, then the device is simple, but continuous or fine adjustment is not provided
Solution Approach 1:
The threaded rod creates a dynamic adjustment system where continuous rotation translates to continuous linear movement of the circuit breaker. This provides smooth, incremental adjustment without jerky or discontinuous movements, making the adjustment process easy to operate while achieving high alignment precision through fine control.
Solution Approach 2:
The threaded rod acts as an intermediary mechanism between the operator's rotational input and the circuit breaker's linear positional change. This intermediary converts easy-to-perform rotational motion into precise linear adjustment, improving ease of operation while maintaining high alignment precision through the mechanical advantage of the thread geometry.

AI summary
A system for adjusting the position of a circuit breaker is provided. The system allows for translation of the circuit breaker with respect to a support base and interfacing mechanisms, such as those that serve to switch the circuit breaker between its operative states. Adjustment is afforded by an adjustment plate fitted to the support base and that moves with the circuit breaker. Slots through the support base allow for movement of the plate and circuit breaker. A threaded member allows for continuous movement of the plate and circuit breaker for accurate positioning.
