Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spring-loaded clips lack control over the motion of lever arms, making them cumbersome to use, and do not offer means to lock open or closed positions, while also failing to provide aesthetic customization and functionality as a stand for electronic devices.
Innovation Solution
A clip design with interchangeable spring and arm components that allow for controlled motion, including constant pressure, varying tension, and temporary locking, along with decorative covers and interior pockets for electronic device security and near-field communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional spring-loaded clips are used, then the basic function of holding money and cards is achieved, but control over lever arm motion is lacking making operation cumbersome
Solution Approach 1:
The patent implements dynamic control of lever arm motion through a cam mechanism that provides varying resistance throughout the opening and closing cycle. The cam profile is specifically designed to create easy-opening motion while maintaining secure closed position, transforming the static spring-loaded mechanism into a dynamically controlled system that adapts resistance based on operational phase.
Solution Approach 2:
The patent introduces a cam mechanism as an intermediary element between the lever arm and the spring-loaded clamp. This cam mediator controls the motion trajectory and resistance characteristics, providing smooth opening motion while maintaining simple overall structure. The cam acts as a motion control interface that simplifies user operation without requiring complex multi-component mechanisms.
2Reliability
If conventional clips are used, then basic clamping function is provided, but means to lock open or closed positions are absent
Solution Approach 1:
The patent incorporates preliminary positioning features in the form of detents or stops built into the cam mechanism. These features are pre-configured to automatically engage at specific positions during the opening and closing cycle, providing automatic locking without requiring additional active components. The closed position is pre-configured for secure engagement, and the open position can be maintained by a second detent for hands-free viewing functionality.
Solution Approach 2:
The cam mechanism is designed to automatically lock the lever arm in desired positions through self-engaging detents and spring-loaded latches. The system uses the existing spring force and cam geometry to create automatic positioning and locking, eliminating the need for separate locking mechanisms or additional energy sources. The mechanism serves itself by using its inherent mechanical properties to achieve position stability.
3Adaptability or versatility
If standard clip designs are used, then functional requirements are met, but aesthetic customization options are limited
Solution Approach 1:
The patent divides the clip into distinct modular components including the body, lever arm, cam mechanism, and cover. Each component can be manufactured separately using different materials, finishes, and design styles, then assembled together. This segmentation allows different aesthetic customizations for each component while maintaining functional integrity, enabling versatile customization without requiring complete redesign of the entire assembly.
Solution Approach 2:
The patent designs the clip with universal mounting interfaces and standardized connection points that allow different cover and component combinations. The base mechanism serves multiple functions (clamping, locking, hands-free viewing) while accepting various aesthetic configurations. This universal design approach enables a single manufacturing platform to produce multiple aesthetic variations, maintaining ease of manufacture while maximizing customization options.
4Shape
If clips are designed to encase all internal parts, then aesthetic appearance is improved, but access to internal components for maintenance becomes difficult
Solution Approach 1:
The patent implements a nested cover structure where the aesthetic cover encases the internal mechanism but can be easily removed or opened. The cover is designed as a removable shell that provides the enclosed aesthetic appearance when assembled, but can be separated to access internal components for maintenance or replacement. This nesting approach maintains the desired enclosed shape during normal use while providing easy access when needed.
Solution Approach 2:
The patent extracts the cover as a separate, removable component from the internal mechanism. This allows the cover to provide the enclosed aesthetic appearance while being independently removable for access to internal parts. The separation of the cover from the core mechanism enables maintenance and repair without compromising the aesthetic design, as the cover can be reattached after service.
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 usability by providing precise control over lever arm movement, aesthetic customization, and functionality as a stand for electronic devices, while securing electronic components with near-field communication capabilities.
Implementation Method 1
The interior component includes a spring member with rolled ends. The lever arms are inserted into the rolled ends of the spring member.
Implementation Method 2
New designs for a spring member that includes options to change the tension of the spring to make the clip easier or harder to open and apply different forces on the material bound within the clip.
