Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional tools with telescopic operational rods are inconvenient for use in dark places as the rod occupies operational space and is not easily accessible when not in use, limiting their functionality for searching objects.

Innovation Solution

A tool with a quick pop-up telescopic head featuring a magnetically adjustable telescopic rod and illuminator, where the telescopic rod can be extended for object retrieval and easily retracted to maintain tool functionality, allowing for convenient use in dark environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a telescopic operational rod is mounted in the front end of the handle, then the tool can retrieve objects in dark places, but the operational space is occupied and the tool is inconvenient to use when the rod is not operated

Engineering Contradiction:

Improveobject retrieval capabilityVSAvoidconvenience of use

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The telescopic rod is nested within the handle body, allowing it to be stored compactly when not in use. The rod can extend outward when needed for object retrieval, then retract back into the handle, eliminating the obstruction problem while maintaining the retrieval capability.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The telescopic rod is designed to be dynamically extendable and retractable, transitioning between a compact stored state and an extended operational state. This dynamic configuration allows the tool to adapt between two usage modes: illumination-only mode (rod retracted) and object retrieval mode (rod extended).

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the telescopic rod is positioned in the front end of the handle, then object retrieval is enabled, but the operational space is occupied

Engineering Contradiction:

Improvemagnetic object attractionVSAvoidoperational space

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The telescopic rod with magnetic tip is nested within the handle's internal cavity, occupying minimal space when retracted. The rod extends only when needed for object attraction, thereby preserving the handle's operational space for other functions when the retrieval feature is not active.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a telescopic rod with magnet is used for object retrieval, then searching capability in dark places is improved, but the tool structure becomes more complex

Engineering Contradiction:

Improvesearching and retrieval functionVSAvoidtool structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges multiple functions into a single integrated tool: the handle provides illumination, the telescopic rod provides extension reach, and the magnetic tip provides object attraction. This combination eliminates the need for separate tools (flashlight + retriever), reducing overall system complexity despite adding features to one tool.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The handle is designed as a multi-functional device that can operate as a standard flashlight when the rod is retracted, and as an object retrieval tool when the rod is extended. This universality allows a single tool to perform multiple tasks, justifying the added structural complexity through functional consolidation.

Inventive Principle:

Principle #6Universality (Multi-functionality)
