Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable cold-hot apparatuses with ring pull structures occupy significant storage volume due to their external design, limiting convenience and usability.
Innovation Solution
A cold-hot apparatus with a hidden ring pull mechanism, featuring rotatable and detachable ring pulls that can be received in fixing grooves, along with a snap fit and notch system for secure attachment, and a compact design incorporating a soft-pack battery and internal components for reduced volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a common fixed ring pull structure is used on the outside of the housing, then the cold-hot apparatus can be attached and fixed to the nursing part, but it occupies significant storage volume and cannot be folded or rotated during use
Solution Approach 1:
The ring pull is designed to be rotatable relative to the housing, transforming from a static fixed structure to a dynamic adjustable component. This allows the ring pull to rotate and adapt to different nursing part angles while being used, resolving the contradiction between ease of operation and volume by providing adjustability without requiring a larger fixed structure
Solution Approach 2:
The ring pull can be received and stored within the fixing groove when not in use, creating a nested configuration where the ring pull fits inside the housing structure. This nesting approach significantly reduces the storage volume occupied by the ring pull while maintaining its functionality when deployed
2Reliability
If a common fixed ring pull structure is used on the outside of the housing, then the cold-hot apparatus can be attached and fixed to the nursing part, but the overall volume is increased and carrying convenience is reduced
Solution Approach 1:
The ring pull is designed to nest within the fixing groove of the housing when not in use, allowing the attachment component to be stored inside the overall structure. This nesting design maintains the reliable attachment function when needed while significantly reducing the overall volume and improving portability
Solution Approach 2:
The ring pull can rotate between a deployed position for attachment and a retracted position for compact storage. This dynamic movement allows the apparatus to transition between functional and compact states, maintaining attachment reliability while reducing overall volume during carrying
