Solution Overview

Problem

Existing wrenches are limited in their ability to reach and manipulate nuts and bolts in difficult locations due to fixed angular positions and lack of versatility in handling various tools.

Innovation Solution

A multi-functional wrench with an archial or curved body and a pivotable ratchet mechanism that allows the ratchet to be positioned at various angles, combined with multiple sockets that can accept various bits or tools, enabling efficient manipulation of nuts and bolts in tight spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wrench has a fixed angular position, then the structure is simple, but it cannot reach nuts and bolts in difficult locations

Engineering Contradiction:

Improveaccessibility to difficult locationsVSAvoidwrench structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The wrench head is made pivotable relative to the handle through a pivot joint, allowing the head to be adjusted to different angular positions. This dynamic adjustment capability enables the wrench to reach nuts and bolts in difficult locations while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The wrench is divided into separate components (handle and head) that can move independently relative to each other. The pivot joint acts as a connection between these segments, allowing angular adjustment of the head while keeping the handle stable.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the wrench has a single working face, then the structure is simple, but it cannot accommodate both left and right side use

Engineering Contradiction:

Improvebidirectional usabilityVSAvoidnumber of working faces

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The wrench is designed with both a first working face and a second working face on opposite sides of the body, each capable of performing fastening and loosening operations. This multi-functional design allows the wrench to be used for both left-side and right-side applications, eliminating the need for separate wrenches.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the ratchet mechanism is fixed in position, then the manufacturing is simple, but it cannot be disposed alternatively on each working face

Engineering Contradiction:

Improveratchet positioning flexibilityVSAvoidratchet mechanism assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The ratchet mechanism is made rotatable about a ratchet mechanism pivot axis, allowing it to be positioned alternatively on the first and second working faces. This dynamic positioning capability provides versatility in operation while maintaining a straightforward manufacturing approach through standardized pivot connections.

Inventive Principle:

Principle #15Dynamics

AI summary

A multi-functional wrench having an adjustable construction and including i) a ratchet mechanism that can be disposed at a plurality of different angular positions with respect to a body of the wrench and ii) a plurality of sockets which are useful for many applications and can accept various bits or tools engageable within the socket. The multi-functional wrench has a body that is archial or curved in shape which is a particular benefit when the wrench is used in difficult to reach areas.
