Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting components in industries like construction and furniture lack economical, easy-to-install, and strong connection solutions that can withstand various loads and moments.
Innovation Solution
A connection system using a combination of hook and tongue components with a custom-built key that imposes force components in multiple directions, allowing for a rigid connection under compression and rotational forces, utilizing precise manufacturing techniques to optimize contact surfaces and geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional connection methods (screws, nails, welds, adhesives) are used, then connection strength is achieved, but installation complexity and time increase
Solution Approach 1:
The connection system divides the connection function into three separate components: a first component with engagement portion, a second component with engagement portion, and a third component (insert) that activates the connection. This segmentation allows each component to be simple in itself while achieving strong connection when assembled, resolving the contradiction between simplicity and connection strength.
Solution Approach 2:
The third component acts as an intermediary element that, when inserted into the space between the first and second components, forcibly displaces the engagement portions outwardly to create the rigid connection. This mediator approach allows the connection to be activated simply by insertion, eliminating complex installation procedures while maintaining strong connection strength.
2Strength
If traditional connection methods are used, then connection strength is achieved, but manufacturing cost increases
Solution Approach 1:
By segmenting the connection system into three separate components, each component can be manufactured independently using simple, cost-effective processes. The engagement portions and the insert can be produced through basic molding or machining operations, avoiding the need for expensive specialized equipment required for traditional connection methods.
Solution Approach 2:
The third component (insert) can be designed as a simple, inexpensive element that performs its connection function and can be easily replaced if needed. This approach reduces manufacturing costs by using simpler materials and processes for the connection mechanism compared to traditional permanent connections.
3Strength
If rigid connection structures are used, then connection strength is improved, but adaptability and flexibility decrease
Solution Approach 1:
The connection system transitions from a static, permanent connection to a dynamic, activatable connection. The engagement portions remain inactive until the third component is inserted, at which point the connection is activated. This dynamic approach allows the same structure to provide strong rigid connection when needed while maintaining the ability to be assembled and disassembled, thus providing adaptability.

AI summary
A connection assembly comprises a first and second components having respective first and second engagement portions, and a third component. The first and second components are adapted to be engaged together via the first and second engagement portions such as to define a space therebetween. The third component is adapted to be longitudinally introduced in the space and to forcibly displace the first and second engagement portions outwardly, thereby connecting the first and second components together. Furthermore, a method comprises assembling the components and longitudinally introducing the third component in the space to forcibly displace the first and second engagement portions outwardly, thereby connecting the first and second components together.
