Button hook pad hanger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator pads face challenges in matching hole spacing with elevator pegs, leading to costly modifications and potential weakening of the pad, as well as difficulties in adjusting pegs, which complicates the attachment process.
Innovation Solution
A flexible trim with adjustable openings, made from materials like nylon, is used to attach to the elevator cover, allowing for easy adjustment to fit various knob configurations without compromising the pad's strength, using techniques like heated blades or radio frequency welding to form and secure the openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If holes are made in the pad to attach to elevator pegs, then the pad can be attached to the elevator wall, but the pad's strength is compromised and additional modifications are costly
Solution Approach 1:
The invention separates the attachment function from the pad itself by introducing a distinct hanger component. The hanger contains the holes for peg attachment, while the pad remains intact without holes. This segmentation allows the pad to maintain its full strength while still achieving attachment capability through the separate hanger component that clips to the pad's edge.
2Adaptability or versatility
If holes are made in the pad to match peg spacing, then the pad can be attached to specific elevator configurations, but making additional holes or modifications is costly and time-consuming
Solution Approach 1:
The hanger is designed with a flexible body that can be bent and shaped to accommodate different peg spacing requirements. This dynamic flexibility allows a single hanger design to adapt to various elevator configurations without requiring custom manufacturing for each spacing pattern, thereby reducing manufacturing costs while maintaining versatility.
Solution Approach 2:
The invention changes the attachment system's parameters by using a continuous flexible hanger material that can be configured in different shapes and sizes. This allows the same basic hanger component to be adapted to various peg spacing parameters without requiring different hole patterns or modifications to the pad itself.
3Ease of operation
If metal hangers or hardware are used to attach pads, then the pad can be secured to the elevator wall, but the attachment process becomes more complex and costly
Solution Approach 1:
The invention replaces rigid metal hangers with a flexible thin film or strip material that forms the hanger body. This flexible material is simpler in construction than traditional metal hardware, easier to install, and can be attached to the pad edge without complex fastening mechanisms. The flexibility allows it to conform to different configurations while maintaining adequate attachment strength.
