Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional sighting devices use fixed center aiming points, then the device structure remains simple, but users cannot adapt to different application scenarios and must purchase multiple devices

Engineering Contradiction:
Improveadaptability to different application scenariosVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the aiming point size adjustable rather than fixed. The display device can dynamically change the size of the first pattern (center aiming point) based on different application scenarios, allowing a single device to adapt to various shooting distances and conditions without requiring multiple fixed-aiming-point devices.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by varying the size parameter of the aiming point. The display device can project different sized first patterns (center aiming points) by changing the display parameters, enabling the same optical device to serve multiple purposes (close-range and long-range shooting) by simply adjusting the aiming point size parameter.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If users purchase multiple sighting devices with different aiming point sizes for different scenarios, then each device is optimized for its specific use, but user expenses increase and convenience decreases

Engineering Contradiction:
Improvemulti-scenario functionalityVSAvoidnumber of devices needed
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies universality by designing a single optical sighting device that can perform multiple functions - serving both as a close-range sight with large aiming points and as a long-range sight with small aiming points. The display device enables this multi-functionality by projecting different sized first patterns according to different shooting scenarios, eliminating the need for users to purchase and manage multiple specialized devices.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the functionality of multiple separate sighting devices into a single integrated device. By combining the optical components with a programmable display device, the system integrates both close-range and long-range aiming capabilities into one device, reducing the quantity of devices users need to own and manage.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If conventional sighting devices have fixed aiming point sizes, then manufacturing and operation are simple, but shooting accuracy cannot be optimized for different distances

Engineering Contradiction:
Improveshooting accuracyVSAvoidoperation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies dynamics by enabling the aiming point size to be dynamically adjusted based on shooting distance and scenario. The display device can switch between different sized first patterns, allowing users to optimize shooting accuracy for both close-range and long-range targets while maintaining relatively simple operation through automated or manual size selection.

Inventive Principle:
Principle #15Dynamics
