Spring-less Infant Hinge for Silent, Secure Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for holding infants, such as those used with warmers, often employ complex spring-loaded mechanisms that can make unpleasant sounds when coupling or decoupling, and lack a reliable spring-less solution for pivotally and removably connecting members with structures.
Innovation Solution
A spring-less hinge system comprising a first hinge piece coupled to a structure and a second hinge piece coupled to a member, allowing the second hinge piece to move from a first position to a second position, enabling secure pivoting and decoupling without springs, using a slot configuration that retains the member in a closed position and allows removal only through directed user action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring-loaded mechanisms are used to couple and decouple members, then the members can be securely retained and easily removed, but the mechanisms become complex and produce unpleasant sounds
Solution Approach 1:
The patent removes the spring component entirely from the hinge mechanism, extracting the source of complexity and noise while maintaining the coupling and decoupling functionality through a purely mechanical slot-and-protrusion design
Solution Approach 2:
The hinge is divided into two separate pieces: a first hinge piece attached to the structure and a second hinge piece attached to the member. This segmentation allows independent movement and simplifies the overall mechanism while maintaining secure retention and easy removal capabilities
2Ease of operation
If spring-loaded mechanisms are used to couple and decouple members, then the members can be securely retained and easily removed, but the mechanisms produce unpleasant sounds
Solution Approach 1:
The spring component is completely removed from the system, eliminating the source of unpleasant sounds generated by spring compression and release while maintaining the functional benefits of secure retention and easy removal
Solution Approach 2:
The patent converts the potential harm of noise into a benefit by designing a silent mechanical system that achieves the same functional outcomes through alternative means, transforming a harmful characteristic into a desirable silent operation
3Ease of operation
If the hinge allows easy removal of the member, then accessibility is improved, but accidental removal may occur
Solution Approach 1:
The hinge employs dynamic positioning with two distinct states: a first position for secure retention during normal use and a second position for enabled removal. The transition between these dynamic states requires deliberate user action, balancing ease of removal with prevention of accidental detachment
4Adaptability or versatility
If the hinge design allows pivoting and removal, then accessibility to the infant is improved, but the mechanism becomes more complex
Solution Approach 1:
The hinge is segmented into two independent pieces that can pivot relative to each other, enabling the member to move between closed and open positions for infant accessibility while maintaining a simple overall structure without complex mechanisms
Solution Approach 2:
The segmented hinge pieces can dynamically transition between fixed and movable states, providing adaptability for infant access while keeping the mechanical structure simple through the use of basic slot-and-protrusion geometry

AI summary
An enhanced hinge and method pivotally and removably connects a member from a structure. In one example, the hinge and method retains the member using a first hinge piece coupled to the structure and a second hinge piece coupled to the member. The first and second hinge pieces may be configured such that the second hinge piece is retained inside the first hinge piece in a closed position and is not free to be decoupled from the first hinge piece but is free to pivot to an open position at the closed position. At the open position the second hinge piece is inverted as compared to its position in the closed position, is free to pass through the first hinge piece and is free to be decoupled from the first hinge piece.
