Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window-type air conditioners integrate indoor and outdoor components, causing noise transmission and blocking sunlight, and existing saddle-type designs lack effective mechanisms for adjusting and securing the connecting part during installation.
Innovation Solution
A saddle-type window air conditioner with locking assemblies on the connecting part, comprising a lock sleeve, lock core, push button, and rack, allowing for adjustable length and secure locking to prevent noise transmission and improve installation flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the connecting part is made adjustable to adapt to windows of different sizes, then the adaptability is improved, but the device complexity increases due to the need for locking and positioning mechanisms
Solution Approach 1:
The locking assembly utilizes spring elasticity to automatically lock the connecting part at desired positions. The spring-loaded lock core engages with rack teeth through elastic deformation, enabling automatic locking without external intervention or complex control systems, thus maintaining simplicity while achieving adjustability.
Solution Approach 2:
The lock core acts as an intermediary element between the push button and the rack. It translates the simple pushing motion into effective locking action through its interaction with the rack teeth and spring, providing a straightforward mechanism that bridges the user input and the locking function.
2Reliability
If the connecting part is made fixed to ensure stability, then the reliability is improved, but the ease of operation deteriorates as adjustment becomes difficult or impossible
Solution Approach 1:
The connecting part transitions from a static fixed structure to a dynamic adjustable one. The rack and lock core mechanism allows the connecting part to be easily repositioned by pushing, while the spring ensures reliable locking at each position, achieving both ease of operation and stability.
Solution Approach 2:
The connecting part is divided into segments marked by rack teeth, allowing it to be adjusted to discrete positions. This segmentation enables easy adjustment to different lengths while maintaining stability at each positioned segment through the locking mechanism.
3Ease of operation
If the locking mechanism is made simple for ease of operation, then the ease of operation is improved, but the reliability may deteriorate due to insufficient locking strength
Solution Approach 1:
The lock core features a cylindrical shape that rotates or moves linearly to engage with the rack teeth. This simple geometric form enables easy operation through pushing or rotating motion while providing sufficient locking strength through the circular contact interface and spring force.
Solution Approach 2:
The rack teeth are designed with asymmetric profiles that engage unidirectionally with the lock core. This asymmetric design ensures strong locking in the engaged position while allowing easy release through the push button, achieving both reliability and ease of operation.

AI summary
A saddle-type window air conditioner comprises an indoor part, an outdoor part and a connecting part. The connecting part includes an indoor connecting box and an outdoor connecting box sleeved in each other. The indoor connecting box is connected with the indoor part, the outdoor connecting box is connected with the outdoor part, and the connecting part is provided with locking assemblies. Each of the locking assemblies includes a lock sleeve, a lock core, a push button and a rack. The lock sleeve is disposed on the indoor connecting box located on an outer side or on the outdoor connecting box, and is provided with a lock hole; the rack is disposed on the outdoor connecting box located on an inner side or on the indoor connecting box; the push button is connected with the lock core and configured to push the lock core to move; and the lock core is provided with a lock pillar. When the lock pillar is clamped and locked with the lock hole, the lock core is separated from the rack to extend or shorten the connecting part. When the lock pillar is separated from the lock hole, the lock core is clamped with the rack, and the connecting part cannot be extended, but can only be shortened under the action of an external force to realize the locking of the connecting part.
