Solution Overview

Problem

Existing handheld reel devices for string lights are inefficient in uninstalling lights from tall Christmas trees, requiring ladders and causing potential damage or disorderly installation due to fixed handle lengths that do not accommodate varying heights.

Innovation Solution

A handheld reel with removable and adjustable handles that can be inserted into rotating ports, allowing for handles of different lengths to facilitate comfortable and neat installation and uninstallation of string lights at heights above the user's reach without a ladder, featuring longitudinally extending members and laterally extending attachments for spooling and unspooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed-length handles are used on the reel, then the device structure is simple, but it cannot accommodate users needing to reach high positions on tall trees

Engineering Contradiction:
Improvehandle length adaptabilityVSAvoidreel structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handle length is made variable through a telescopic mechanism with adjustable segments. Users can extend or retract the handle to different lengths by manipulating the telescopic segments, allowing adaptation to various tree heights and user reach requirements while maintaining a relatively simple overall reel structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The handle is divided into multiple telescopic segments that can be independently extended or retracted. This segmentation allows the handle to achieve variable lengths through a series of smaller mechanical components rather than requiring a completely complex adjustable mechanism, thus improving adaptability while controlling structural complexity.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If a ladder is used to reach high tree positions, then user reach is extended, but the installation process becomes more complex and time-consuming

Engineering Contradiction:
Improveuser reach distanceVSAvoidinstallation time
Core Design Contradiction:
Length of moving objectVSLoss of time

Solution Approach 1:

The telescopic handle provides a dynamic, extendable reach mechanism that allows users to access high tree positions directly from the ground or stable positions. By extending the handle to appropriate lengths, users can install lights on tall trees without needing to set up and reposition ladders, significantly reducing installation time and procedural complexity.

Inventive Principle:
Principle #15Dynamics

3Productivity

If string lights are flung onto high tree branches, then installation speed is increased, but the lights become disordered and tree damage may occur

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The reel with extended handle allows users to preliminarily position and guide the string lights onto the tree branches from a stable position. The extended reach enables careful, controlled placement of lights along the branches before final securing, ensuring orderly installation and preventing tree damage while maintaining efficient installation speed.

Inventive Principle:
Principle #10Preliminary action
