Infant dining chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Most infant dining chairs lack adjustable height, making them inconvenient for use in various settings, particularly in restaurants where sanitation and comfort for infants need to be considered.
Innovation Solution
The design incorporates front and rear chair leg adjusting units with elastic positioners and height adjusting holes, allowing users to easily adjust the chair height by engaging and disengaging the elastic positioners into corresponding holes, enabling the chair legs to be adjusted to suitable positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chair leg length is fixed, then the manufacturing is simple, but the adaptability to different environments is poor
Solution Approach 1:
The chair leg adjusting mechanism transforms the fixed chair leg into a dynamic, adjustable structure. The telescopic connection allows the chair leg length to change between extended and retracted positions, enabling adaptation to different table heights and environments while maintaining a relatively simple overall structure through the use of guide grooves and elastic pieces.
Solution Approach 2:
The adjusting mechanism employs a nested structure where the adjustable chair leg components are housed within the chair body structure. The telescopic connection allows inner components to extend and retract within the outer chair leg housing, providing adjustability without significantly increasing the overall device footprint or complexity.
2Adaptability or versatility
If the chair leg is made adjustable, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The elastic piece automatically engages with the guide groove to lock the chair leg at the extended position without requiring additional locking mechanisms or complex control systems. The spring-loaded elastic piece provides self-locking functionality, maintaining the adjusted height while minimizing the complexity of the adjusting mechanism.
Solution Approach 2:
The patent replaces complex mechanical locking systems with a simpler elastic deformation-based locking mechanism. The elastic piece deforms to engage with the guide groove, providing a reliable lock without requiring multiple moving parts, screws, or complex actuating mechanisms, thus reducing overall device complexity.
3Reliability
If the chair leg structure is simplified, then the ease of manufacture is improved, but the reliability of height adjustment is reduced
Solution Approach 1:
The guide groove acts as an intermediary element that guides the elastic piece during the adjusting process. This simple grooved structure ensures reliable engagement and disengagement of the elastic piece, providing dependable height adjustment and locking functionality while maintaining ease of manufacture through the use of a single molded or machined groove feature.
