Gun Sight Insert Locking Feature for Adhesive-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun sights with self-illuminating inserts face challenges in secure fixation, requiring precise alignment and adhesive application, leading to increased assembly time and costs.
Innovation Solution
A locking feature integrated into the insert body secures it within the gun sight without adhesives, using elastic deformation and mechanical interaction to ensure reliable connection, reducing assembly time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to fix insert into gun sight, then reliable connection is achieved, but assembly time increases
Solution Approach 1:
The patent replaces the adhesive-based chemical bonding system with a mechanical locking system. The locking feature includes a locking portion that engages with a locking recess in the gun sight, and a clearance portion that provides elastic deformation to facilitate insertion and secure retention without requiring adhesives.
Solution Approach 2:
The locking feature is designed to be self-securing through elastic deformation. The clearance portion deforms elastically during insertion to accommodate tolerances and then locks into place automatically within the locking recess, eliminating the need for external adhesives or additional securing steps.
2Reliability
If precise alignment is required during assembly, then reliable fixation is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent uses elastic deformation as a key parameter to accommodate dimensional variations and alignment tolerances. The clearance portion deforms elastically to compensate for manufacturing tolerances, allowing reliable locking without requiring extremely precise alignment during assembly.
Solution Approach 2:
The clearance portion is designed with elastic deformation capability that acts as a built-in compensation mechanism. This elastic cushioning accommodates alignment errors and tolerance variations before the locking engagement occurs, ensuring reliable fixation without complex alignment procedures.
3Reliability
If adhesive application is required, then secure fixation is achieved, but manufacturing cost increases
Solution Approach 1:
The patent eliminates the need for adhesive materials and application processes by implementing a purely mechanical locking system. The locking portion engages with the locking recess through elastic deformation, removing the cost associated with adhesives and their application/curing processes.
Solution Approach 2:
The patent extracts and removes the adhesive component from the fixation system entirely. The locking feature provides all necessary fixation functions through mechanical engagement and elastic deformation, eliminating the need for adhesive materials and associated manufacturing steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The locking feature provides a secure, reliable, and cost-effective assembly process for gun sight inserts, enhancing manufacturing efficiency and insert durability.
Implementation Method 1
A clearance portion can be fixed to one of the first locking portion or the second locking portion. The clearance portion can be configured to contact a third portion of the interior of the gunsight to control an insertion depth of the insert into the gunsight by compensating any axial clearance between the locking feature of the insert and the engagement portion of the gun sight.
Data Source
AI summary
Systems for providing an illuminated insert for a gun sight include an insert that is inserted into a gun sight. The insert can have an illuminator that provides a source of illumination to improve visual acquisition of the sight. The insert is secured in an opening in the sight by a locking feature that contacts portions of an interior of the sight to secure the insert into the sight. The insert can be secured solely by the mechanical interactions of the locking feature without any further techniques, such as adhesives or the like. The insert is not removable from the sight without the use of destructive techniques to ensure security of the insert.
