Pliable Harness Spacer for Quick Dual-SRL Bracket Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dual self-retracting lifeline (SRL) brackets for fall protection harnesses require time-consuming adjustments to attach and detach, as they necessitate loosening and re-tightening of the webbing to accommodate and remove the accessory from the harness.
Innovation Solution
A harness spacer with a pliable base and arched members forming an H-shape, allowing easy attachment and detachment by bending to accommodate webbing and accessories like dual-SRL brackets without readjusting the harness webbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual-SRL bracket is attached to the harness webbing, then the harness can accommodate two self-retracting lifelines, but the webbing must be loosened and adjusted to create space for the bracket
Solution Approach 1:
The patent introduces a mounting plaque as an intermediary component between the harness webbing and the dual-SRL bracket. The plaque is attached to the webbing once, and then the bracket attaches to the plaque without requiring webbing adjustments. This intermediary structure resolves the contradiction by decoupling the attachment process from webbing manipulation.
Solution Approach 2:
The mounting plaque is installed in advance on the harness webbing, creating a prepared interface for subsequent bracket attachment. This preliminary action eliminates the need for time-consuming webbing adjustments when the dual-SRL bracket needs to be attached or removed.
2Ease of operation
If the webbing is loosened to attach the dual-SRL bracket, then the bracket can be secured to the harness, but the harness webbing must be re-tightened after bracket removal
Solution Approach 1:
The mounting plaque serves as a stable intermediary that remains fixed to the harness webbing. The dual-SRL bracket attaches to and detaches from this plaque without affecting the webbing tension, thereby maintaining both ease of operation and productivity.
Solution Approach 2:
The attachment system is segmented into three independent components: the harness webbing, the mounting plaque, and the dual-SRL bracket. This segmentation allows the bracket to be attached or removed from the plaque without requiring adjustments to the webbing, thus improving time efficiency while maintaining ease of operation.
3Adaptability or versatility
If the webbing is adjusted frequently to attach and remove accessories, then the accessories can be easily installed and removed, but the process becomes time consuming
Solution Approach 1:
The mounting plaque acts as a permanent intermediary structure that enables repeated accessory attachments and removals without requiring webbing adjustments. This resolves the contradiction by providing a stable interface that maintains adaptability while eliminating time loss from frequent adjustments.
