Front-Access Belt Anchorage Assembly for Secure Webbing Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt systems require access to the back of the receptacle for assembly, limiting their application and increasing assembly effort due to the need for a pin to be inserted into a loop from the rear.
Innovation Solution
A method and belt system design where a belt anchor with spring arms allows the free end of the webbing to be guided and secured from the front, eliminating the need for rear access, using a fixing element that is attached to the webbing and passed through the receptacle's opening before the belt anchor is inserted, securing it in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin is inserted into a loop from the rear of the receptacle for assembly, then the belt strap can be connected to the receptacle, but the assembly process requires access to the back of the receptacle which limits application areas and increases assembly complexity
Solution Approach 1:
The patent inverts the traditional assembly sequence by first inserting the free end of the belt strap through the receptacle opening from the front, then inserting the belt anchor with its pin from the front, and finally retracting the pin into the loop. This reverses the conventional approach where the pin would be inserted from the rear, thereby enabling assembly from the front only and eliminating the need for rear access.
Solution Approach 2:
The patent applies preliminary action by pre-attaching the pin to the belt anchor before insertion. The pin is already positioned on the belt anchor in a ready state, allowing it to be inserted through the loop from the front along with the belt anchor itself, rather than requiring separate rear access to attach the pin after the belt strap is positioned.
2Reliability
If rear access is required for pin insertion, then secure connection can be achieved, but the device complexity and assembly steps increase
Solution Approach 1:
The patent merges the insertion of the belt anchor and the pin into a single unified action. Both components are inserted together from the front through the receptacle opening, eliminating the need for separate steps and rear access. This combining of operations simplifies the assembly procedure while maintaining secure connection.
Solution Approach 2:
The patent inverts the traditional assembly sequence by first inserting the free end of the belt strap through the receptacle opening from the front, then inserting the belt anchor with its pin from the front, and finally retracting the pin into the loop. This reverses the conventional approach where the pin would be inserted from the rear, thereby enabling assembly from the front only and eliminating the need for rear access.
