Spring Clamp with Datum Spacer for Binder Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spine clamp binder technologies are time-consuming and expensive due to methods like gluing, folding, or riveting for attaching tension sheets to spring clamps.
Innovation Solution
A media binder arrangement with a spring clamp having a tension sheet mounted inside a cavity with a datum spacer, where the tension sheet is attached to the cover and the spring clamp is positioned in the spine, allowing for faster and less expensive production by using a method involving forming metal springs and attaching liners to plastic bars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gluing, folding or riveting methods are used to attach tension sheet to spring clamp, then the attachment is secure, but the production process becomes time-consuming and expensive
Solution Approach 1:
The tension sheet is nested inside the cavity of the spring clamp, with the datum spacer also positioned within the cavity. This nested arrangement allows the tension sheet to be securely held without requiring external attachment methods like gluing or riveting, thus maintaining reliability while simplifying the production process and improving productivity.
2Reliability
If gluing, folding or riveting methods are used to attach tension sheet to spring clamp, then the attachment is secure, but the production cost increases
Solution Approach 1:
The tension sheet is nested inside the cavity of the spring clamp, eliminating the need for expensive attachment processes like gluing or riveting. This nested configuration maintains secure attachment while significantly reducing production costs and simplifying manufacturing.
Solution Approach 2:
The spring clamp's cavity structure itself provides the attachment mechanism for the tension sheet, rather than requiring separate attachment components or processes. The cavity walls and datum spacer work together to automatically secure the tension sheet in place, making the system self-sufficient and reducing manufacturing complexity.
3Force
If acute angles are used in spacer walls, then clamping force is enhanced, but the structure becomes more complex
Solution Approach 1:
The acute angles are applied locally only to the spacer walls that contact the tension sheet, rather than making the entire spring clamp structure complex. This localized application of acute angles enhances clamping force precisely where needed while keeping the rest of the structure simple and easy to manufacture.
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
Enables quicker and more cost-effective production of spine clamp binders by simplifying the attachment process and enhancing clamping force through acute angles in the spacer walls, effectively holding bundles of papers.
Implementation Method 1
The sides exerting a spring force towards each other in an activated position
Implementation Method 2
Each side of the spring clamp having an acute angle towards the clamp base... The more acute angle towards the clamp base the larger clamping force of a given spring clamp properties
