Solution Overview

Problem

Conventional screwdrivers with storage functions have insufficient storage space and can only accommodate sockets and tool heads of specified specifications, making them inconvenient to use.

Innovation Solution

A screwdriver design featuring a movable storage assembly with interchangeable storage seats, allowing for the accommodation of different types and sizes of tool heads or sockets, facilitated by an engaging mechanism and release assembly for easy detachment and replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional tool handle with storage functions is used, then the screwdriver can store sockets and tool heads, but the storage space is insufficient and can only accommodate sockets and tool heads of specified specifications

Engineering Contradiction:
Improvestorage compatibilityVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The storage assembly is divided into multiple storage seats (first storage seat and second storage seat) that can be independently configured. Each storage seat can accommodate different specifications of sockets and tool heads, allowing the system to segment storage functionality to achieve greater versatility and capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage assembly is designed to be movable relative to the handle, transitioning between a retracted position (stored within the handle) and an extended position (protruding outward). This dynamic configuration allows the storage space to be accessible when needed while maintaining a compact form when not in use.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the storage assembly is made detachable and changeable, then various tool heads and sockets can be accommodated, but the structure becomes more complex

Engineering Contradiction:
Improvestorage flexibilityVSAvoidengaging mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The engaging mechanism utilizes the movable nature of the storage assembly to create dynamic engagement and disengagement. The storage assembly can be easily detached by moving it to a specific position where the engaging portions disengage, and reattached by moving it to the engaged position, simplifying the operation despite the detachable design.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The engaging mechanism is designed to automatically engage and disengage based on the position of the storage assembly. When the storage assembly is moved to the engaged position, the engaging portions automatically mate together without requiring additional fastening operations. Similarly, moving the storage assembly to the disengaged position automatically releases the connection.

Inventive Principle:
Principle #25Self-service

AI summary

A screwdriver includes a handle, a fixed stem, a storage assembly and an engaging mechanism. The handle includes a housing defining an inner space. The fixed stem defines an axial direction and is disposed on the housing and protrudes into the inner space. The storage assembly includes a movable stem and at least one storage seat disposed on the movable stem, and the movable stem is movably sleeved with the fixed stem. The engaging mechanism includes at least one first engaging portion disposed on the fixed stem, a second engaging portion disposed on the movable stem and a release assembly. The release assembly is operatable to abut against the second engaging portion so that the second engaging portion is disengaged from said first engaging portion, and the storage assembly is detachable from the fixed stem and removable from the handle.
