Solution Overview

Problem

Conventional mass transfer columns require welding of polymeric members, which is difficult, dangerous, and can weaken the structural integrity of the components due to changes in polymer chains during the welding process.

Innovation Solution

A clamp system featuring a lock with snap lock arms and a deformable elastic annular head portion that securely couples polymeric components without welding, using a key to provide releasable retention and prevent release, fabricated from flexible synthetic polymer materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If welding is used to join polymeric members, then structural integrity can be achieved, but the polymer chains are weakened due to changes during the welding process

Engineering Contradiction:
Improvestructural integrityVSAvoidpolymer chain integrity
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent replaces the welding process (thermal/chemical system) with a mechanical clamping system consisting of a clamp body, lock mechanism, and key. This mechanical substitution avoids exposing polymeric members to welding heat that degrades polymer chains, while still achieving secure structural joining through mechanical interlocking and clamping forces.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Strength

If welding is used to join polymeric members, then permanent bonding is achieved, but the process becomes difficult and dangerous

Engineering Contradiction:
Improvebonding strengthVSAvoidassembly ease
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The joining system is segmented into separate components: a clamp body, a lock mechanism, and a key. This segmentation allows for easier manufacturing of individual parts and simplifies the assembly process, as components can be assembled in a standardized sequence without requiring complex welding operations. The modular design makes the system easier to manufacture and assemble compared to traditional welding of polymeric members.

Inventive Principle:
Principle #1Segmentation

3Reliability

If a lock mechanism is used to secure the clamp, then release prevention is achieved, but the device complexity increases

Engineering Contradiction:
Improverelease preventionVSAvoidclamp structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The key serves as an intermediary element that mediates between the user and the lock mechanism. Rather than requiring complex electronic or mechanical locking systems, the simple key provides effective release prevention through a straightforward mechanical interaction with the lock and snap lock arms. This intermediary approach achieves reliable security without significantly increasing overall device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A clamp includes a lock and a key. The lock defines a first longitudinal axis, and the key defines a second longitudinal axis. The lock has a clamping body portion, a pair of opposing snap lock arms, and an annular shaped receptacle. Each snap lock arm has a mounting end integrally joined to the clamping body portion. Each snap lock arm is flexible about its mounting end. The annular shaped receptacle is defined by the pair of opposing snap lock arms, being disposed between the pair of opposing snap lock arms adjacent to the mounting ends. The key includes a wedge body portion and a deformable elastic annular head portion. The annular head portion releasably retains the key in the lock. The annular head portion is sized to engageably cooperate with the annular shaped receptacle to provide the releasable retention.
