Solution Overview

Problem

Conventional tool holders require a high number of manipulations for storing customizable tools after use, as users need to disengage and separate multiple locking members and parts before placing them back in storage.

Innovation Solution

A holder with movable unlocking members and resilient retaining mechanisms that allow for easy engagement and retention of replaceable tool parts, reducing the steps required for storage by allowing simultaneous insertion and retention of multiple parts, such as jaws of pliers, within a storage box.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional storage boxes are used for storing handles and replaceable parts, then the parts can be stored separately, but the number of manipulations required for storing and retrieving parts is high

Engineering Contradiction:
Improveease of storageVSAvoidtime for storage operations
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The holder combines multiple storage functions into a single device. It can simultaneously hold replaceable parts and, when coupled with the handle, forms a complete tool. This merging eliminates the need for separate storage boxes for handles and parts, reducing the number of manipulation steps required for storage and retrieval operations.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple locking members are used to secure replaceable parts to handles, then the connection is secure, but the number of steps to assemble and disassemble the tool is high

Engineering Contradiction:
Improveconnection securityVSAvoidnumber of assembly steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is segmented into a first locking member on the replaceable part and a second locking member on the handle. These segmented locking members can engage independently, allowing the replaceable part to be securely connected to the handle through a simplified two-step process rather than requiring multiple locking operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The holder acts as an intermediary device that simplifies the interaction between the replaceable part and the handle. By providing a structured interface with integrated locking members, the holder mediates the connection process, making it more reliable and easier to operate than direct connection methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a holder with unlocking members is used, then the replaceable parts can be easily released, but the holder structure becomes more complex

Engineering Contradiction:
Improveease of part releaseVSAvoidholder structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The unlocking members are designed to be movable relative to the holder body. This dynamic capability allows the unlocking members to transition between engaged and disengaged positions, enabling easy release of replaceable parts. The movable nature of these components provides functional complexity without requiring a completely complex holder structure.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention deals with a holder (22, 23) for holding a replaceable part (1) of a tool, such as a replaceable jaw of pliers, wherein the replaceable part (1) comprises a first locking member (6), and wherein the tool further comprises a handle (3) comprising a second locking member (8), wherein one of the first and second locking members (6, 8) is moveable relative to the other locking member between: • an engaged position wherein the second locking member (8) is engaged with the first locking member (6) so as to lock the replaceable part (1) to the handle (3), and • a disengaged position wherein the second locking member (8) is disengaged from the first locking member (6) so as to allow the replaceable part (1) and the handle (3) to be separated, wherein the holder (22, 23) comprises a cavity (32) for receiving the replaceable part (1), and an unlocking member (36) adapted to move said one of the first and second locking members (6, 8) from the engaged position to the disengaged position when the replaceable part (1) is received in the cavity (32).
