Hook With Rack-and-Pinion Dynamic Petal Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional decorative hooks have complex structures requiring power devices, leading to increased volume and cost, and lack interactivity, making them less engaging for users.
Innovation Solution
A hook with dynamic display featuring a housing, rotary disc, rotatable petals, draw hook, and springs, utilizing a gear-rack transmission mechanism driven by a linear motion to create a 'flower blooming' effect through simple pulling actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If electric or spring power devices are used to drive dynamic pendants, then dynamic display effect is achieved, but device volume increases and cost rises
Solution Approach 1:
The patent removes power devices (motors, batteries) from the system entirely. Instead, it extracts and utilizes the gravitational force acting on the pendant itself as the driving force, which naturally provides continuous motion without additional components.
Solution Approach 2:
The pendant structure serves its own dual purpose: it is both the decorative element and the driving mechanism. The weight of the pendant itself drives the rotation through the cord-winding mechanism, eliminating the need for separate power sources.
2Duration of action of moving object
If electric or spring power devices are used to drive dynamic pendants, then dynamic display effect is achieved, but manufacturing cost increases
Solution Approach 1:
The patent removes power devices (motors, batteries) from the system entirely. Instead, it extracts and utilizes the gravitational force acting on the pendant itself as the driving force, which naturally provides continuous motion without additional components.
Solution Approach 2:
The patent employs simple, inexpensive mechanical components such as cords, pulleys, and basic linkages instead of expensive electronic or motorized systems. These simple mechanical parts are cost-effective and easy to manufacture.
3Device complexity
If traditional static design is used for decorative hooks, then structural simplicity is maintained, but interactivity and user engagement are lacking
Solution Approach 1:
The patent transforms the static pendant into a dynamic system where components move relative to each other. The cord can wind and unwind, causing the pendant to rotate and change its displayed information, creating an interactive experience that responds to user manipulation.
Solution Approach 2:
The system provides visual feedback through the dynamic display of information on the pendant. As users manipulate the cord and rotate the pendant, different faces or sides are revealed, providing immediate visual response to user actions and encouraging continued interaction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances fun and interactivity with a dynamic display effect, optimizing space and maintaining structural simplicity while providing a multi-layered three-dimensional display.
Implementation Method 1
A rack is provided within the guide slot, and the rack is engaged with the gear for transmission
Implementation Method 2
Another end of the draw hook provided at an exterior of the housing is configured to move under an external force to engage the rack with the gear for transmission
Implementation Method 3
the springs are configured to drive the draw hook for resetting, causing the rotary disc to rotate and retract the rotatable petals from the slots
