Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking structure is turned to clamp with the track to achieve detachable connection, then the connection stability is improved, but the locking degree is difficult to control and production complexity increases
Solution Approach 1:
The locking fastener automatically locks with the connection member when inserted, eliminating the need for manual adjustment or complex control mechanisms. The structure self-regulates the locking degree through its geometric design, where the locking fastener's shape and the connection member's features work together to achieve a predetermined locking state without requiring operator skill or complex controls.
Solution Approach 2:
The patent changes the locking mechanism from a rotational clamping action requiring degree control to a linear insertion action with automatic engagement. By transforming the locking motion from rotational to translational and using the spacer's elastic deformation as a parameter change, the system achieves stable locking without complex control, as the locking fastener naturally settles into the correct position upon insertion.
2Ease of operation
If a locking structure is turned to clamp with the track, then detachable connection is achieved, but the locking degree is difficult to control during assembly
Solution Approach 1:
The locking fastener and connection member are designed with complementary geometric features that automatically engage at the correct locking degree upon insertion. The structure serves itself by using the insertion motion to automatically position the locking fastener at the precise engagement point, eliminating the need for operators to control or measure the locking degree.
Solution Approach 2:
The connection member is pre-designed with specific geometric features (such as grooves or protrusions) that guide the locking fastener into the correct position during insertion. This preliminary design of the engagement geometry ensures that when the locking fastener is inserted, it automatically achieves the proper locking degree without requiring manual adjustment or precision control during assembly.
3Strength
If a screw is turned to lock the locking structure, then connection is achieved, but the locking degree is difficult to control and assembly efficiency decreases
Solution Approach 1:
The locking fastener automatically achieves the correct locking strength through its insertion motion, eliminating the need for operators to control torque or rotation degree. The structure self-regulates the locking force through its geometric design, where the locking fastener's engagement features naturally provide the required locking strength upon insertion, improving assembly efficiency by removing the skill-intensive turning operation.
Solution Approach 2:
The patent replaces the rotational screw mechanism with a linear insertion mechanism. Instead of requiring rotational torque control to achieve locking, the system uses the linear insertion motion of the locking fastener combined with elastic deformation of the spacer to achieve both connection and locking. This substitution eliminates the need for torque control and significantly improves assembly efficiency.

AI summary
A track light, including a track, a lamp and latch structures connecting the track and the lamp. Each latch structure comprises a latch member, a connection member, a gasket and a locking member. The lamp is provided with mounting portions and mounting holes penetrating through the mounting portions. The connection members penetrate through the mounting holes and extend out of the lower surfaces of the mounting portions. The locking members are inserted from bottom to top into the connection members and are locked to be fixed to the tail ends of the connection members. The gaskets are sleeved on the outer side of the tail ends of connection members and are pressed to be fixed between the lower surfaces of the mounting portions and the locking members. The connection members are configured to penetrate through the mounting holes and then extend out of the lower surfaces of the mounting portions.
