Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of zoom and focus rings is used, then the electronic apparatus can be adjusted, but the adjustment becomes cumbersome and difficult to manage especially when installed in hard-to-reach locations
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated adjustment mechanism. A drive unit (motor) is provided that can automatically rotate the zoom ring and focus ring based on control signals, eliminating the need for manual operation. This substitution of mechanical manual adjustment with automated motor-driven adjustment directly resolves the contradiction by improving ease of operation while managing device complexity through automation.
Solution Approach 2:
The patent introduces a control unit as an intermediary between the user and the adjustment rings. The control unit receives adjustment commands and translates them into rotational movements of the zoom and focus rings through the drive unit. This intermediary layer simplifies the user interface and makes adjustment easier, especially for remote installations, while the control logic manages the complexity of the adjustment mechanism.
2Stability of the object's composition
If locking mechanisms are added to fix adjustment members, then the adjusted position can be fixed, but the device complexity increases
Solution Approach 1:
The patent employs a self-locking mechanism where the drive unit automatically maintains the adjusted position of the zoom and focus rings without requiring separate locking components. The motorized drive unit can hold the rings at any position through controlled electromagnetic force, eliminating the need for additional mechanical locking mechanisms like knobs or clips. This self-service approach provides stable positioning while avoiding the complexity of separate locking systems.
Solution Approach 2:
The patent replaces traditional mechanical locking mechanisms (such as locking knobs or clips) with an automated motorized holding system. The drive unit uses electromagnetic force to maintain the adjustment rings at their set positions, substituting mechanical locking with electromagnetic holding. This reduces device complexity by eliminating separate locking components while maintaining stable adjustment positions.
3Strength
If elastic members are used to hold the base member and electronic device, then secure attachment is achieved, but the device complexity increases
Solution Approach 1:
The patent uses elastic members (springs) as simple, inexpensive components to provide secure attachment between the base member and the electronic device. These elastic members are designed to be simple, reliable, and replaceable if needed. By using simple elastic components rather than complex mechanical fastening systems, the patent achieves strong attachment while minimizing the increase in device complexity.
