Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the apparatus uses fixed-length supporting legs, then the structure is simple and stable, but it cannot adapt to uneven ground or different processing machine heights
Solution Approach 1:
The supporting legs are designed with telescopic mechanisms that allow them to extend and retract, transforming from fixed-length to variable-length structures. This enables the apparatus to adapt to uneven ground and different processing machine heights while maintaining structural integrity through controlled mechanical movement.
Solution Approach 2:
The supporting legs are divided into multiple telescopic segments that can independently adjust their length. This segmentation allows each leg to be adjusted separately to compensate for ground irregularities and achieve the required height variations without compromising overall structural stability.
2Adaptability or versatility
If the apparatus is designed with fixed dimensions, then manufacturing is simple, but it cannot be compatible with various wood processing machines
Solution Approach 1:
The apparatus incorporates telescopic supporting legs that can be adjusted to different heights and configurations, allowing a single apparatus design to accommodate various wood processing machines with different mounting heights and positions, eliminating the need for multiple fixed-dimension variants.
Solution Approach 2:
The apparatus is designed with universal adjusting capabilities that enable it to work with different types of wood processing machines. The telescopic mechanism provides a range of positions and configurations that can accommodate various machine interfaces, making one apparatus design universally applicable rather than requiring machine-specific variants.
3Ease of operation
If the apparatus is transported on a trailer, then it can be moved to desired locations, but valuable trailer space is occupied
Solution Approach 1:
The telescopic supporting legs can be retracted into a compact configuration during transport, significantly reducing the apparatus's overall volume and allowing it to occupy less space on trailers or other transport equipment, thereby freeing up valuable cargo space while maintaining full functionality when deployed.
4Adaptability or versatility
If the apparatus uses telescopic supporting legs with arresting mechanisms, then height adjustment is enabled, but device complexity increases
Solution Approach 1:
The telescopic supporting legs incorporate arresting mechanisms that allow controlled extension and locking at desired heights. The mechanism uses mechanical interlocks or locking elements that engage at specific intervals along the telescopic segments, providing stable height adjustment without requiring complex continuous control systems.

AI summary
An apparatus for hoisting and forwarding of logs enables the forwarding of logs along an axis towards a processing area. The apparatus is adjustable in height either due to various configuration of ground or to various heights of processing area in various wood processing machines, and is comfortable both for each user as well as for manufacturers and distributors. The apparatus is also easy to transport to any desired locations by using a tractor. To this aim, supporting legs on the apparatus are telescopic and connected a bearing framework, with a movable part engaging the ground. Bearing members on a hoisting unit are telescopic and embedded in the bearing framework, with a displaceable part engaging the ground. The bearing framework may be provided on its side and faced away from the hoisting unit, as well as furnished with a coupling member for connecting the apparatus to a tractor.
