Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Envelopes with windows present catch points during the insertion of collation materials, leading to jams in mail inserters due to the edges of the window interfering with the insertion process.

Innovation Solution

A mail inserter system that includes a deck with a securing mechanism and an air suction module to hold the envelope in place, using a first securing element between the window and an open edge and a second element between the window and a closed edge, along with a deflection element to guide the collation away from the window edges, and an air suction module to prevent the edges from becoming catch points by applying negative air pressure through apertures on the deck.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If envelopes with windows are processed for collation insertion, then the envelope structure is maintained, but the edges of the window present catch points causing jams during insertion

Engineering Contradiction:

Improveinsertion process reliabilityVSAvoidcatch points at window edges

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A deflection element is introduced as an intermediary component between the collation material and the window edges. This deflection element guides the collation material away from the harmful catch points at the window edges, allowing the insertion process to proceed without jams while maintaining the envelope structure intact

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The harmful function of the window edges (creating catch points) is extracted and isolated by positioning the deflection element to intercept the collation material before it reaches the window edges. This separates the beneficial window feature from the harmful edge effects, allowing the window to remain while preventing the catch points from causing jams

Inventive Principle:

Principle #2Taking out (Extraction)

2Stability of the object's composition

If a securing mechanism is added to hold the envelope, then insertion stability is improved, but device complexity increases

Engineering Contradiction:

Improveenvelope stability during insertionVSAvoidsecuring mechanism complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mechanical securing function is replaced by a pneumatic system. Air suction holes in the deck create negative pressure to hold the envelope in place during insertion, eliminating the need for complex mechanical clamps or fixtures. This substitution reduces mechanical complexity while maintaining envelope stability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

A pneumatic securing mechanism is implemented using air suction holes in the deck. Negative pressure generated by the air suction module holds the envelope firmly in the insertion area without requiring mechanical contact elements. This pneumatic approach simplifies the overall device structure compared to traditional mechanical securing methods

Inventive Principle:

Principle #29Pneumatics and hydraulics

AI summary

An inserting system is provided for securing an envelope having a window. The system includes a deck slidably supporting the envelope, where the deck defines an insertion area, and a securing mechanism in the insertion area securing the envelope in an insertion location during insertion of a collation. The securing mechanism includes a first securing element selectively securing a first portion of the envelope between the window and an open edge of the envelope and a second securing element selectively securing a second portion of the envelope between the window and a closed edge of the envelope. The inserting system may also include a deflection element disposed on the deck between the first securing element and the second securing element, wherein the deflection element guides the collation away from an edge of the window.
