Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conductor contact is allowed to move freely in the mounting slot, then the assembly process is simpler, but the electrical connection reliability deteriorates due to misalignment and disengagement
Solution Approach 1:
The mounting slot is pre-formed with a tapered structure during the base body manufacturing process, creating built-in limiting structures that automatically guide and position the conductor contact in the correct location before assembly, preventing misalignment and disengagement without requiring additional complex positioning components
Solution Approach 2:
The limiting structures are integrated directly into the mounting slot of the base body, combining the functions of guidance, positioning, and electrical connection in a single unified structure, thereby improving reliability without significantly increasing device complexity
2Reliability
If limiting structures are added to restrict conductor contact movement, then electrical connection reliability improves, but the device complexity increases
Solution Approach 1:
The limiting structures are implemented as localized tapered features within the mounting slot rather than as separate components, concentrating the functional complexity in specific critical areas while keeping the overall structure simple and minimizing the number of parts
Solution Approach 2:
The limiting structures are merged with the mounting slot structure itself, so that the base body simultaneously provides both the mounting function and the limiting function through its integrated tapered design, eliminating the need for separate limiting components

AI summary
A lamp holder includes a base body, a cover, and a conductor contact. The base body has a first end and a second end opposite to each other, and is provided with a mounting slot extending along a first direction from the first end towards the second end. The cover is detachably connected to the first end of the base body, wherein the cover and the base body are configured to accommodate a wire therebetween. The conductor contact is disposed within the mounting slot and electrically connected to the wire. A limiting structure is provided on at least one of the base body or the conductor contact, configured to restrict movement of the conductor contact relative to the base body along the first direction.
