Adjustment Device with Segmented Detent and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopic sight adjusting devices have a coarse click detent that is difficult to refine, leading to unclear distinction between locking positions and inadequate space for a readable scale, making precise adjustments challenging, especially in dark conditions where passive optical representation is difficult, increasing the risk of incorrect adjustments.
Innovation Solution
An adjusting device with a rotatable adjusting cap and a coupling part that includes a first latching device for fine adjustments and a second latching device with different detent means for coarse adjustments, providing tactile feedback and visual display means to ensure accurate positioning, even in the dark, through a two-part latching system with varying resistance and display elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single detent device with fine detent is used for precise adjustment, then adjustment precision is improved, but the adjustment range becomes limited and the distinction between locking positions becomes unclear
Solution Approach 1:
The detent device is divided into two independent detent devices: a first detent device with fine detent for precise adjustments and a second detent device with coarse detent for large-range adjustments. Each detent device operates independently with its own detent means, allowing the system to achieve both high precision and wide adjustment range simultaneously.
2Adaptability or versatility
If the rotational range of the adjustment mechanism is extended beyond a full turn, then adjustment range is improved, but the user cannot tell which setting or sub-range the mechanism is currently in
Solution Approach 1:
The adjustment mechanism is segmented into multiple sub-ranges, with each sub-range indicated by a distinct detent device. The first detent device covers one full rotation while the second detent device covers multiple rotations, allowing users to identify the current sub-range through the active detent device.
Solution Approach 2:
The system provides tactile feedback through distinct detent sensations from the two detent devices, allowing users to感知 the current setting position. The different detent patterns provide immediate feedback about which sub-range is active without requiring visual confirmation.
3Measurement precision
If fine detent with large number of clicks is used for large adjustment range, then adjustment precision is improved, but the user will miscount during adjustment making precise adjustments unreliable
Solution Approach 1:
The adjustment process is segmented into two stages: coarse adjustment using the second detent device with fewer, more distinct clicks for rapid positioning, and fine adjustment using the first detent device with finer detent for precise final positioning. This segmentation reduces the total number of clicks the user must count while maintaining high precision.
Solution Approach 2:
The second detent device acts as an intermediary that facilitates easier navigation through large adjustment ranges with fewer, more distinct tactile markers. This intermediary mechanism reduces the cognitive load of counting by providing intermediate reference points every 5-10 clicks of the fine detent device.
4Device complexity
If passive optical representation is used for visual display, then device complexity is reduced, but the representation is difficult or impossible to perceive in the dark
Solution Approach 1:
The patent replaces passive optical representation with active tactile feedback mechanisms. The two detent devices provide distinct tactile sensations that are perceptible in complete darkness, eliminating the need for illuminated displays while maintaining adjustability and verification capabilities.
