Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If quick-action reticle adjustment means are mounted reversibly on the adjustment turret, then ease of operation is improved, but reliability deteriorates due to play in the mounting
Solution Approach 1:
The coupling peg is designed to be dynamically positionable between a fixing position (engaged with the receiving shaft) and a release position (disengaged from the receiving shaft). This dynamic positioning allows the mounting state to be changed on demand, providing both secure fixation during use and easy removal when needed, thus resolving the contradiction between operational ease and mounting stability.
Solution Approach 2:
The mounting connection is segmented into discrete states through the coupling peg's ability to occupy different positions. The fixing position provides stable engagement for normal operation, while the release position allows easy dismounting. This segmentation enables the system to switch between reliable mounted state and easily adjustable state, resolving the contradiction.
2Reliability
If the coupling peg is held in the fixing position, then reliability is improved, but ease of operation deteriorates due to inability to quickly dismount
Solution Approach 1:
The coupling peg's dynamic positioning capability allows it to be held securely in the fixing position during normal operation, providing reliable mounting stability. When dismounting is needed, the coupling peg can be quickly moved to the release position, enabling easy removal without complex tools or procedures, thus resolving the contradiction between reliability and ease of dismounting.
Solution Approach 2:
The coupling mechanism is designed to be self-servicing through the blocking spring and annular groove interaction. The blocking spring automatically engages with the annular groove to lock the coupling peg in the fixing position, maintaining reliability without additional fastening operations. For dismounting, the user simply needs to move the coupling peg to the release position, and the spring automatically disengages, providing easy operation without complex release mechanisms.
3Reliability
If the blocking spring projects into the receiving shaft, then reliability is improved through secure engagement, but device complexity increases due to additional components
Solution Approach 1:
The blocking spring's function is merged with the coupling peg's positioning function. The spring projects into the receiving shaft to provide secure engagement when the coupling peg is in the fixing position, while also facilitating automatic disengagement when moved to the release position. This merging of functions reduces the need for separate locking and release mechanisms, thereby reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The blocking spring acts as an intermediary element between the coupling peg and the receiving shaft. It provides the necessary engagement security by projecting into the receiving shaft when engaged, while its elastic properties allow it to flex and disengage smoothly when the coupling peg is moved to the release position. This intermediary role simplifies the overall mounting mechanism compared to rigid locking systems.

AI summary
A telescopic sight system includes a telescopic sight and a setting assembly. The telescopic sight has a housing, an objective lens assembly, a reticle element, an adjustment mechanism, and an adjustment turret. The setting assembly can be reversibly coupled to the adjustment turret and has a coupling peg and a peg carrier. A receiving shaft and a blocking spring are arranged in the adjustment turret. The coupling peg has two annular grooves. A groove bottom of the first annular groove is arranged at a smaller spacing than the spring width from an outer edge of the receiving shaft. The second annular groove is recessed with respect to the first annular groove. The blocking spring lies in the first annular groove when the coupling peg has been arranged in the fixing position, and in the second annular groove when the coupling peg has been arranged in the release position.
