Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surface contact and rotation during assembly and disassembly are used to engage mounting parts, then ease of operation is improved, but positioning accuracy and repeatability deteriorate due to surface wear
Solution Approach 1:
The patent employs conical surfaces (cone and counter-cone) instead of flat rotating surfaces. The cone is arranged in the opening of the coupling element, and the matching counter-cone is formed in the pin. When engaged, these conical surfaces provide precise axial positioning through their geometric shape without requiring rotational grinding, thereby maintaining positioning accuracy while enabling easy assembly and disassembly through axial movement only.
Solution Approach 2:
The mounting device is divided into two separate mounting parts: a first mounting part connected to the telescopic sight and a second mounting part fixed to the handgun. Each part has its own coupling elements (cone in the first part, counter-cone in the second part), allowing independent positioning and engagement without affecting the other part's integrity, thus maintaining precision while facilitating easy assembly.
2Adaptability or versatility
If repeated assembly and disassembly occur with surface contact, then adaptability is improved, but reliability deteriorates due to increasing wear affecting repeatability
Solution Approach 1:
The conical surfaces of the cone and counter-cone are designed to engage through purely axial movement rather than rotational contact. This geometric engagement method eliminates the wear that would occur with repeated rotational assembly and disassembly, ensuring that positioning repeatability is maintained even after multiple assembly cycles. The conical geometry provides self-centering and precise positioning without surface degradation.
3Ease of operation
If 90° rotation is required for clamping, then ease of operation is improved, but device complexity increases due to additional rotation mechanism
Solution Approach 1:
The patent eliminates the need for 90° rotation by using conical surfaces that engage through purely axial movement. The cone and counter-cone are designed such that when the first mounting part is moved axially toward the second mounting part, the conical surfaces automatically engage and clamp together without requiring any rotational movement. This simplifies the assembly mechanism while maintaining ease of operation.
Solution Approach 2:
Instead of using rotation to achieve clamping (as in conventional mounting devices), the patent inverts the approach by using purely axial movement to engage the conical surfaces. The clamping force is generated through the geometric convergence of the cone and counter-cone during axial approach, rather than through rotational tightening, thereby reducing mechanical complexity.
